Built: 68

Modifications:

project 50- basic serial project (1954)

project 50PLO- a modernized version with enhanced anti-submarine weapons (in 1959-60) ( see text )

Despite all the positive results obtained during the tests, the first post-war domestic TFR was built in a limited series, and on the personal instructions of I.V. Stalin, the development of TTZ for a new patrol ship with a total displacement of 1200 tons began project 50.

The Council of Ministers of the USSR ordered the Ministry of the Shipbuilding Industry and the Naval Ministry to develop project 50 of the new TFR and build the lead ship on this basis within the following timeframes:

a) complete the development of a preliminary design in September and submit it to the USSR Council of Ministers in October 1950;

b) complete the development of the technical project in February and submit it to the USSR Council of Ministers in March 1951;

c) start building the lead ship in the 2nd quarter of 1951 and present it for state trials in the 3rd quarter of 1952.

All work was entrusted to TsKB-820. In July-August 1950, various technical issues were being coordinated, which would make it possible to obtain the given displacement and the necessary qualities of the ship. However, in the given dimensions, it was not possible to fully fulfill the requirements for wind resistance. Studies have shown that with a linear placement of the power plant, it is possible to provide displacement at a given level. In the course of the study, a combined scheme of two machine-boiler plants was considered. For it, boilers with blowing into furnaces of the KVG-57/28 type were created at SKKB. The boilers were with natural circulation, vertical, with a developed radiation surface, one-way flue gas flow, two-front heating. The superheated steam temperature was assumed to be moderate (370°C), and the operating pressure was up to 28 kg/sq.cm. The new design scheme of the ship's boiler was the basis for the creation of highly accelerated small-sized boilers for all classes of post-war surface warships. The most important task of the subsequent high forcing of the furnace with an increase in its thermal load by three times was solved. After numerous disputes, the linear arrangement of the power plant was adopted.

Options with weapons very different from the . So it was supposed to replace two B-34USM bow mounts with one twin closed-type mount with the same 100-mm guns as in the B-34USM. The development of such an installation was then carried out in OKB-172. Attempts were also made to replace the MBU-200 with the MBU-600 and 37mm machine guns with 25mm. Nevertheless, the final composition of the ship’s armament differed from only a decrease in the number of B-34USM installations from 4 to 3, the number of torpedo tubes from 3 to 2, and a decrease in artillery ammunition by 15%.

The preliminary design was completed by the Leningrad branch of TsKB-820 on time. In the process of its consideration by the Acting Minister of the Navy, Admiral A.G. Golovko approved a proposal to replace 4 BMB-1s with 4 BMB-2s. The standard displacement obtained in the preliminary design was 1,059 tons. In the technical design, the standard displacement increased to 1,068 tons. In the process of reviewing the technical design, the submitted kit and on time, it turned out that it was impossible to store and use the ammunition equipped with TGA on the ship in strict accordance with the current instructions. Due to the additional volumes received on the ship, even with the existing standard displacement, it became possible to take almost twice as much fuel (at the highest displacement) and bring the cruising range to almost 2000 miles. The presence of only a two-tube torpedo tube instead of the traditional three-tube one was constantly criticized. Finally, when approving the technical project, it was decided to oblige SKB-700 SMEs by order of the MTU Navy to develop in 1951 technical project three-pipe torpedo tube as applied to ships Project 50. Subsequently, these devices were developed and installed on the ships of this project.

Chief Designer of the TFR Project 50 at first it was D.D. Zhukovsky, then V.I. Neganov, and at the final stage, from the end of 1953, B.I.

Ship Project 50 as well as the TFR, it was smooth-deck with longitudinal sheer, single-tube, with one mast and two superstructures. Nasal PM formations were significantly sharpened compared to TFR, which, according to experts, should have significantly reduced splash formation. This PM was used by the last chief designer in his future projects. A closed passage was provided for all combat posts and premises, with the exception of the N6 bomb cellar, the midshipman's compartment and the steering compartment, which was unusual for such a small ship. Anti-fragmentation armor with a thickness of 7-8 mm was reserved for the power plant compartments, the wheelhouse and the shields of artillery installations. The entire hull is electrowelded, except for the connection of the upper deck with the side and removable sheets. According to the test results, both general and local strength were found to be satisfactory. The vibration of the aft end on all strokes turned out to be less than that of the EM Project 30 bis and complied with the regulations.

On sea trials, the ship, with a normal displacement of 1134 tons, developed an average speed of 29.5 knots at 386 rpm propellers. Despite the reduction in the number of revolutions compared to, it was not possible to get rid of the erosion on the suction sides of the blades at the hub of the propellers. The ship, like its predecessor, had two rudders, but the screws, due to the larger diameter (reduction in the number of revolutions), now protruded beyond the main line. This circumstance worsened the conditions for the passage of the ship through inland waterways and made navigation on the shallows and in the mouths of rivers more dangerous. As a result of the seaworthy tests carried out at a sea state of 4.5 and 6 points, it was found that with 4 points of excitement, the speed of the ship and the use of any combat and technical means were not limited. With greater excitement, the speed decreased to 23 knots (6 points). With a sea state of 6 points, the main artillery can only be used at speeds up to 16 knots, the use of torpedo, anti-submarine and mine weapons is impossible.

Overall rating maneuverability and seaworthiness of the ship was found to be satisfactory. The seaworthiness of the ship in terms of the use of weapons was estimated at 4 points, although in waves up to 6 points it is possible to use artillery weapons.

The turbo-gear unit of the TV-9 ship was a single-hull active-reactive single-flow turbine with a capacity of 10,000 hp, a single-flow surface condenser located along the axis with a power split. TV-9 could be put into operation from a cold state. During the period of state tests of serial ships, breakdowns of rotor blades began to be detected. A special commission chaired by Professor M.I. Grinberg found out that these failures were due to resonant vibrations at full speed (front and rear). The manufacturing plant and its SKBT took increased voltages against those previously accepted in marine turbine construction, did not provide structurally and technologically high-quality manufacturing. In April and September 1954, resolutions of the Council of Ministers of the USSR were adopted, in pursuance of which defects in the TV-9 turbines were corrected. In this regard, a temporary restriction was introduced on the maximum speed, limited to 25 knots. The restrictions were lifted in 1955. However, in the future there were malfunctions with these turbines.

Three 100-mm guns of the B-34USMA type were installed on the ship. The aiming of the gun mounts was carried out automatically using remote control and manually. It was the first domestic universal gun mount with automatic remote guidance from a rangefinder post (PUS "Sphere-50"). There were no serious comments to the AU, however, as well as on the guide tray, it bent during operation, and the sleeve deflector did not always ensure the free fall of the sleeves. To control the firing of 100-mm artillery, a stabilized sighting post SVP-42-50 was installed, combined with the Anchor radar antenna. The range of its action on a sea target is 180 cab, and on an air target up to 165 cab. The twin-pipe torpedo tube installed on the ship was intended for firing only straight-line steam-gas torpedoes of the 53-38, 53-39, 53-ZEU, 53-51 types. New in the radio-technical armament of the ship compared to the TFR was the adoption of the Lin type radar as a radar for detecting surface targets, which could detect low-flying aircraft and the Pegasus-2 hydroacoustic station. With a TFR speed of about 20 knots, this sonar was able to detect submarines at periscope depth at a distance of 14 cabs, and an anchor mine - 7 cabs (only 3 cabs were specified according to the technical specifications).

Despite the many shortcomings that were revealed in the main power plant due to TV-9 breakdowns, the construction of the ships of Project 50 proceeded quite quickly and by the end of 1958 the entire series of 68 ships was built. TFR comparison Project 50 of the first series with foreign analogues shows that if our ship surpasses them in driving performance, then it was significantly inferior in cruising range. This is understandable, since our ships were not intended to escort ocean convoys. An integral assessment of weapons shows that the TFR Project 50 was at the level of the TFR "Butler" built during the BMB and was inferior to the TFR of the "Dili" type built in the 50s (both US Navy). For artillery weapons, if we consider only the maximum firing range and the magnitude of a minute salvo, then the TFR Project 50 somewhat superior to foreign counterparts, however, their turret installations made it possible to use artillery in conditions of more intense splashing and unrest. Finally, the automatic 76-mm artillery mounts of the TFR "Dili" were much more effective than the domestic B-34USMA mounts when firing at air targets. In terms of anti-submarine weapons, the superiority of the Dili TFR was significant. So, its torpedo tubes used already homing anti-submarine torpedoes, the Mk108 jet bomb launcher had an effective firing range of 4.5 cabs and a rate of fire of up to 12 rounds per minute, and the GAS installed on it had a detection range of submarines of more than 30 cabs. Only for ships upgraded according to project 50PLO, anti-submarine weapons and their means of support began to more or less correspond to that time, but the leading maritime powers already had other ships with even greater anti-submarine capabilities.

Modifications. Almost all TFR pr.50 of the Russian Navy in 1959-1960. have been upgraded to project 50PLO. Anti-submarine weapons were reinforced on them: the MBU-200 bomb launcher was replaced by two RBU-2500s, the two-tube TA was replaced by a three-tube TTA-53-50 for firing homing anti-submarine torpedoes, the Pegas-2 GAS was replaced by Pegas-3M. The ships of the early series had the Guys-1M4 radar, which was later replaced by the Fut-N radar. The Anchor fire control radar as part of the SVP-42-50 was replaced by the Anchor-M2 radar, and the Lin radar by the Neptun-M radar. On two ships (SKR-76 and Lun) they installed the Don navigation radar, on the Jaguar in 1957 - the MG-16 Sviyaga sonar of underwater communication. In connection with changes in weapons, the components of the load also changed. To maintain stability at a given level, it was necessary to place solid ballast on the TFR of the latest series and on modernized ones.

TFR "Arkhangelsk Komsomolets" in 1973-74. underwent repairs with the modernization and dismantling of the torpedo tube, in place of which a cabin with electronic warfare equipment was placed. On the roof of the cabin, 4 fairings of interference emitters were installed and one more - on the second platform of the mast (behind the radar), similar in design to the ground-based complex SPN-40 (1RL238). In the felling room there were two aviation stations SPS-22 and SPS-44 for setting active jamming and a search and jamming station SPB-7. The ship was part of the White Sea Naval Base, where it provided cover with interference from NATO reconnaissance aircraft of the Navy's training grounds during testing of submarines and missile launches in the Nenoksa area.

On the TFR "Jaguar", converted into an experimental ship OS-188 in 1977, the firing radar MR-100 "Sail" was experimentally tested. The station's antenna post was installed on the cabin roof instead of the SVP-42-50, which was moved to the aft superstructure.

On some ships, during the service, weapons systems not provided for by the project were installed: on the SKR-59 and SKR-73 in 1971, two twin 25-mm 2M-3M assault rifles were installed; on SKR-59 in 1971, two 45-mm 21KM assault rifles were installed; on several ships, an anti-sabotage OGAS MG-7 "Bracelet" was installed, on some - a sonar of sound underwater communications MG-26 "Khosta". On one of the TFRs, the anti-submarine system PLRKK-4500 "Burun" was tested - four six-barreled launchers for firing RKB depth jet bombs were installed at the stern.

Two TFRs sold to Finland, where they were reclassified as frigates and renamed "Hameenmaa" and "Uusimaa", were modernized by the Finns to fit their requirements. An additional 30-mm double-barreled AK-230M assault rifle (on the tank) was installed on them, and the V-11M aft anti-aircraft guns were replaced with 40-mm single-barreled Bofors. Since 1971, both ships have been converted into minelayers. They removed the aft 100-mm gun and mounted a room for mine ammunition.

Five TFRs built in China were upgraded into URO frigates - instead of torpedo tubes, built-in anti-ship missile launchers were installed on them.

Construction program. Head TFR project 50 was laid down on the slipway of plant No. 445 (now the plant named after 61 Kommunar) in Nikolaev on December 20, 1951 and received the name "Ermine", launched on July 30, 1952. He was accepted into the Navy after lengthy tests only on July 30, 1954. In total, 68 ships were built before 1958: at plant No. 445 (named after 61 Communards) in Nikolaev - 20 units, at Shipyard No. 820 ("Yantar") in Kaliningrad - 41, at Shipyard No. 199 (named after Lenkom) in Komsomolsk -on-Amur - 7. This was the first largest program for the construction of the TFR of the domestic fleet, after EM Project 30 bis- the second largest series of ships in the domestic fleet with a displacement of more than 1000 tons.

Export. 17 ships from the USSR Navy were sold to the following countries: Bulgaria - SKR-67 in 1957 (renamed Darzki); SKR-53 in 1958 ("Smelli"); "Kobchik" in 1985 ("Baudry"); Indonesia - "Puma", "Sarych", "Korsak" and "Grizon" in 1963 (renamed accordingly to "Slamet Rijari", "Jons Sudarso", "Ngurah Rai" and "Mongin Sidi"); "Pelican" in 1964 ("Nuku"); "Bison", "Bison" and "Stork" in 1965 (renamed "Hang Tuan", "Kaki Ali" and "Lambung Mangkurat"); GDR - "Deer" in 1956 ("Ernst Thalmann"); "Tour" in 1957 ("Karl Liebknecht"); "Sable" and "Raccoon" in 1959 ("Karl Marx" and "Friedrich Engels"); Finland - SKR-69 and "Filin" in 1964 (renamed to "Hameenmaa" and "Uusimaa"). In addition, in China, after the transfer of full documentation under the Soviet license, 5 more TFRs were built, later converted by the Chinese into URO frigates.

Status. Patrol ships Project 50 (50PLO) served in the Navy in all four fleets. The last ships of this series were decommissioned in 1990-91.

Performed a combat mission to assist the armed forces of Egypt: TFR "Jaguar" in 1967 and 1971; TFR "Panther" in 1970; TFR "Marten" in 1967 and 1973; TFR "Raven" in 1967 and 1968; SKR-57 in 1968; Syrian armed forces: SKR "Marten" in 1968; armed forces of Egypt and Syria: SKR-77 in 1973

Patrol ships of the project 50 type "Ermine"(according to NATO classification - Riga class frigate) - warships of the Navy of the USSR, developed after the Second World War. They came to replace the project 42 watchdogs. It was developed in two modifications: modification 50 and modification 50-PLO (with enhanced anti-submarine weapons).

Story

Requirements

After the release of the first Project 42 patrol ship, the Council of Ministers of the USSR ordered the Ministry of the Shipbuilding Industry and the Naval Ministry to take control of the development of the Project 50 patrol ship and the construction of the lead ship with a displacement of 1200 tons according to these drawings, and the following deadlines were set for work:

• complete the development of a draft design in September and submit it to the USSR Council of Ministers in October 1950;
• complete the development of the technical project in February and submit it to the USSR Council of Ministers in March 1951;
• start building the lead ship in the 2nd quarter of 1951 and present it for state trials in the 3rd quarter of 1952

All work was entrusted to TsKB-820. In July-August 1950, various technical issues were being coordinated that would make it possible to ensure the implementation of the TTZ, but it was not possible to fully meet the requirements for wind resistance in the given sizes.

Design

Studies of engines have shown that with a linear placement of the power plant, it is possible to provide displacement at a given level, and a combined scheme of two machine-boiler plants was considered. For this purpose, boilers with blast into furnaces of the KVG-57/28 type with natural circulation, vertical shape, with a developed radiation surface, one-way flue gas flow and two-front heating were created at SKKB. The temperature of the superheated steam reached 370°C, which was considered a moderate temperature, and the operating pressure reached 28 kg/cm². The new design scheme of the ship's boiler was the basis for the creation of highly accelerated small-sized boilers for all classes of surface warships of post-war construction, thereby solving the most important task of subsequent high boosting of the furnace with an increase in its heat load three times. After numerous disputes, the linear arrangement of the power plant was adopted.

Options with weapons that were very different from Project 42 were considered: it was supposed to replace two B-34USM bow mounts with one twin closed-type mount with the same guns (it was developed at OKB-172). Attempts were also made to replace the MBU-200 with the MBU-600, and the 37-mm machine guns with the 25-mm ones. However, everything was limited to a decrease in the number of B-34USM installations from four to three, the number of torpedo tubes from three to two, and a decrease in artillery ammunition by 15%.

The preliminary design was completed by the Leningrad branch of TsKB-820 on time. In the process of its consideration by the Acting Minister of the Navy, Admiral A. G. Golovko approved a proposal to replace the BMB-1 class bombers with the BMB-2 class. The standard displacement obtained in the preliminary design was 1,059 tons, in the technical design it increased by another 9 tons. Due to the additional volumes received on the ship, it became possible to take almost twice as much fuel (at the highest displacement) and bring the cruising range to almost 2000 miles.

However, in the further process of consideration, it turned out that it was impossible to ensure the storage and use of ammunition equipped with TGA in strict accordance with the current instructions on the ship. Also, the presence of only a two-tube torpedo tube instead of the traditional three-tube one was constantly criticized. Finally, when approving the technical project, it was decided to oblige SKB-700 to rework the project by order of the MTU of the Naval Forces, having worked out the option of installing a three-tube torpedo tube, which was successfully completed.

At first, D. D. Zhukovsky was the chief designer, then V. I. Neganov received this position, and at the final stage, from the end of 1953, B. I. Kupensky became. The observer from the Navy was Captain 1st Rank V.S. Avdeev.

Description

Uniform and armor

The ship was smooth-deck with longitudinal sheer, single-tube, with one mast and two superstructures. The nasal formations in the theoretical drawing were significantly pointed compared to project 42, which should have significantly reduced splash formation (this drawing was used by the last chief designer in his future projects). A closed passage was provided for all combat posts and premises, with the exception of the bomb cellar No. 6, the midshipman's compartment and the steering compartment, which was unusual for a small ship. The compartments of the main power plant, the wheelhouse and the shields of artillery installations were booked with anti-fragmentation armor 7-8 mm thick. The entire hull was electro-welded, except for the connection of the upper deck with the side and removable sheets. According to the test results, the overall and local strength were found to be satisfactory. The vibration of the stern end on all strokes was less than that of destroyers 30 bis and corresponded to temporary standards.

Speed ​​indicators

On sea trials, the ship at normal displacement developed an average speed of 29.5 knots at 386 propeller revolutions per minute, which was less than that of Project 42. However, even this did not help get rid of erosion on the suction sides of the blades at the propeller hub. The ship had two rudders, but the propellers, due to the larger diameter, now protruded beyond the main line, and this worsened the conditions for the passage of the ship through inland waterways, making it more dangerous to navigate in shallows and in estuaries. On sea trials at sea state 4, 5 and 6 points, it was found that at 4 points of swell, the speed of the ship and the use of any combat and technical means were not limited, with a swell of 6 points, the speed was reduced to 23 knots, and only the main artillery (at speeds up to 16 knots). The general assessment of the maneuverability and seaworthiness of the ship was considered satisfactory. The seaworthiness of the ship in terms of the use of weapons was estimated at 4 points.

Engine

The turbo-gear unit of the TV-9 ship was a single-case active-reactive single-flow turbine with a capacity of 10,000 horsepower and a single-flow surface condenser located along the axis with a power split. TV-9 could be put into operation from a cold state. During the period of state tests of serial ships, breakdowns of rotor blades began to be detected. A special commission, chaired by Professor M. I. Grinberg, found out that these breakdowns arose due to resonant vibrations at full speed (both forward and rear). The manufacturing plant and its SKBT adopted increased voltages against those previously accepted in marine turbine construction, without providing structurally and technologically high-quality manufacturing. In April and September 1954, resolutions of the Council of Ministers of the USSR were adopted, pursuant to which defects in the TV-9 turbines were corrected, in connection with which a temporary restriction on the maximum speed (25 knots) was introduced until 1955, but malfunctions with these turbines arose and in the future.

Armament

Three 100-mm guns of the B-34 USMA type were installed on the ship. The aiming of these gun mounts was carried out automatically using remote control, as well as manually. It was the first domestic universal gun mount with automatic remote guidance from a rangefinder post (PUS "Sphere-50"). There were no serious comments on them, but it was found that the guide tray sagged during operation, and the sleeve deflector did not always ensure the free fall of the sleeves. To control the firing of 100-mm artillery, a stabilized sighting post SVP-42-50 was installed, combined with the Anchor radar antenna, whose range for a sea target was 180 cab, and for an air target - up to 165 cab. The twin-pipe torpedo tube installed on the ship was intended for firing only straight-line steam-gas torpedoes of types 53-38, 53-39, 53-ZEU, 53-51. New radio equipment was installed - the Lin surface target detection radar, which could detect low-flying aircraft, and the Pegas-2 hydroacoustic station, which, at a speed of about 20 knots, was capable of detecting submarines at periscope depth at a distance of 14 cab, and an anchor mine - 7 cab (with a minimum requirement of 3 cab).

Comparison with foreign courts

By the end of 1958, a series of 68 ships had been built. Comparison of patrol ships of the project 50 of the first series with foreign counterparts shows that the ship was superior to them in terms of driving performance, but inferior in cruising range, since it was not intended to escort ocean convoys (like all Soviet ships). According to the overall armament, it was equivalent to the USS Butler DD-636 patrol aircraft and inferior to the USS Dealey DE-1006, it was superior in maximum firing range and the magnitude of a minute salvo, but was not used in conditions of intense splashing; finally, anti-aircraft and anti-submarine weapons were not as effective as those of American destroyers: there were no homing torpedoes, the firing range of bombers and GAS was low. The 50-PLO project made it possible to catch up with the Dili in armament, but at that time more efficient ships began to appear.

Modifications

Almost all Project 50 ships were modernized in the -1960s, being equipped with new weapons: the MBU-200 bomber was replaced with two RBU-2500s, the two-tube torpedo tube was replaced with a three-tube TTA-53-50 for firing homing anti-submarine torpedoes, the Pegas- 2" - on the "Pegasus-3M". The Anchor fire control radar as part of the SVP-42-50 was replaced with the Anchor-M2 radar, the Lin radar with the Neptun-M radar, the Guys-1M4 radar with the Fut-N radar . In connection with changes in armament, the components of the load also changed: in order to maintain stability at a given level, it was necessary to place solid ballast.

Construction

The lead ship was laid down on the slipway of plant No. 445 (now the plant named after 61 Communards) in Nikolaev on December 20 and received the name "Ermine", launched on July 30, 1952. It was accepted into the Navy after lengthy tests only on July 30, 1954. In total, 68 ships were built before 1958: at plant No. 445 (named after 61 Communards) in Nikolaev - 20 units, at Shipyard No. 820 ("Yantar") in Kaliningrad - 41, at Shipyard No. 199 (named after Lenkom) in Komsomolsk -on-Amur - 7. This was the first largest program for the construction of the TFR of the domestic fleet, after the 30-bis project - the second largest series of ships in the domestic fleet, with a displacement of more than 1000 tons. In addition, 4 ships according to our documentation were built in China. One of the ships, Arkhangelsk Komsomolets, even underwent repairs in 1973-1974 with the modernization and dismantling of the torpedo tube.

Application

17 ships from the USSR Navy were sold to the following countries: Bulgaria - SKR-67v (renamed Darzki); SKR-53 in ("Dare"); "Kobchik" in ("Baudry"); Indonesia - "Puma", "Buzzard", "Korsak" and "Grison" in ("Slamet Rijari", "Jons Sudarso", "Ngurah Rai" and "Mongin Sidi"); "Pelican" in ("Nuku"); "Bison", "Bison" and "Stork" in ("Hang Tuan", "Kaki Ali" and "Lambung Mangkurat"); GDR - "Deer" in ("Ernst Thalmann"); "Tour" in ("Karl Liebknecht"); "Sable" and "Raccoon" in ("Karl Marx" and "Friedrich Engels"); Finland - SKR-69 and "Filin" in (renamed to "Hameenmaa" and "Uusimaa"). In addition, in China, under a Soviet license, 5 more TFRs were built, converted by the Chinese into URO frigates. The last ships of this series were decommissioned in 1990-91. These vessels carried out the combat mission of assisting the armed forces of Egypt and Syria during the wars with Israel.

An excerpt characterizing Project 50 Patrol Ships

The man was in a state of absolute shock for a long time ... Apparently, everything he heard sounded wild to him, and certainly did not coincide with what he really was, and how he treated such a terrible evil that did not fit into normal human frames. ...
- How can I compensate for all this?! .. After all, I can’t do it? And how to live with it?!.. - he clutched his head... - How many I killed, tell me!.. Can anyone say that? What about your friends? Why did they go for it? But why?!!!..
- So that you can live as you should ... As you wanted ... And not as someone wanted ... To kill the Evil that killed others. Because, probably ... - Stella said sadly.
“Forgive me, dear ones... Forgive me... If you can...” the man looked completely killed, and I was suddenly “pricked” with a very bad premonition...
- Well, I do not! I exclaimed indignantly. “Now you must live!” Do you want to nullify all their sacrifice?! Don't even dare to think! Now you will do good instead of them! That will be right. And leaving is the easiest thing. And you no longer have that right.
The stranger stared at me dumbfounded, apparently not expecting such a violent outburst of "righteous" indignation. And then he smiled sadly and said quietly:
- How did you love them! .. Who are you, girl?
My throat was very tight and for some time I could not squeeze out a word. It was very painful because of such a heavy loss, and, at the same time, I was sad for this "restless" person, who would be oh so difficult to exist with such a burden...
- I am Svetlana. And this is Stella. We're just walking around here. We visit friends or help someone when we can. True, now there are no friends left ...
- Forgive me, Svetlana. Although it probably won't change anything if I ask your forgiveness every time... What happened happened, and I can't change anything. But I can change what happens, can't I? - the man glared at me with his blue eyes, like the sky, and, smiling, with a sad smile, said: - And one more thing ... You say that I am free in my choice? .. But it turns out - not so free, dear .. Rather, it looks like atonement for guilt ... With which I agree, of course. But it's your choice that I have to live for your friends. Because they gave their lives for me.... But I didn't ask for it, did I?.. Therefore, it's not my choice...
I looked at him, completely dumbfounded, and instead of “proud indignation” that was ready to immediately escape from my lips, I gradually began to understand what he was talking about ... No matter how strange or insulting it may sound - but all this was the real truth! Even if I didn't like it at all...
Yes, I was very hurt for my friends, for the fact that I would never see them again ... that I would no longer have our wonderful, “eternal” conversations with my friend Luminary, in his strange cave filled with light and warmth ... that the funny places found by Dean will no longer be shown to us by laughter Maria, and her laughter will not sound like a cheerful bell ... And it was especially painful that this completely unfamiliar person would now live instead of them ...
But, again, on the other hand, he did not ask us to interfere ... He did not ask us to die for him. Didn't want to take someone's life. And now he will have to live with this heaviest burden, trying to “pay off” with his future actions the guilt, which in reality was not his fault ... Rather, it was the fault of that terrible, unearthly creature who, having captured the essence of our stranger, killed "right and left."
But it certainly wasn't his fault...
How was it possible to decide who was right and who was wrong, if the same truth was on both sides? somehow decide only between “yes” and “no” ... Since in each of our actions there were too many different sides and opinions, and it seemed incredibly difficult to find the right answer, which would be right for everyone ...
Do you remember anything at all? Who were you? What is your name? How long have you been here? - to get away from a sensitive, and no one pleasant topic, I asked.
The stranger thought for a moment.
My name was Arno. And I only remember how I lived there, on Earth. And I remember how I "left" ... I died, didn't I? And after that I can’t remember anything else, although I would very much like to ...
- Yes, you "left" ... Or died, if you prefer. But I'm not sure if this is your world. I think you should inhabit the "floor" above. This is the world of "crippled" souls... Those who killed someone or seriously offended someone, or even simply deceived and lied a lot. it scary world, probably the one that people call Hell.
“Where are you from then?” How could you get here? Arno was surprised.
- It's a long story. But this is really not our place ... Stella lives at the very "top". Well, I'm still on Earth...
- How - on Earth ?! he asked dumbfounded. – This means – you are still alive?.. But how did you end up here? Yes, even in such horror?
“Well, to be honest, I don’t like this place too much either ...” I shivered, smiling. – But sometimes there are very good people. And we are trying to help them, as we helped you ...
- And what should I do now? I don't know anything here... And, as it turned out, I also killed. This means that this is exactly my place... Yes, and someone should take care of them, - Arno said affectionately patting one of the kids on the curly head.
The kids stared at him with ever-increasing confidence, but the girl generally grabbed on like a tick, not intending to let him go ... She was still quite tiny, with big gray eyes and a very funny, smiling face of a cheerful monkey. In normal life, on the "real" Earth, she must have been a very sweet and affectionate, beloved child. Here, after all the horrors experienced, her clean, laughing face looked exhausted and pale to the limit, and horror and longing constantly lived in her gray eyes ... Her brothers were a little older, probably 5 and 6 years old. They looked very scared and serious , and unlike their little sister, did not express the slightest desire to communicate. The girl, the only one of the trio, apparently was not afraid of us, as she quickly got used to her “newly-born” friend, already quite briskly asked:
- My name is Maya. And can I, please, stay with you? .. And brothers too? We don't have anyone now. We will help you, - and turning to Stella and me, she asked, - Do you live here, girls? Why do you live here? It's so scary in here...
With her incessant barrage of questions and her manner of asking two people at once, she strongly reminded me of Stella. And I laughed heartily...
– No, Maya, of course we don't live here. It was you who were very brave to come here yourself. It takes a lot of courage to do something like this... You are really good! But now you have to go back to where you came from, you have no more reason to stay here.
– Did mom and dad die “completely”?.. And we won’t see them anymore… Really?
Maya's plump lips twitched, and the first large tear appeared on her cheek... I knew that if this wasn't stopped right away, there would be a lot of tears... And in our current "generalized" state, it was absolutely impossible to allow this...
"But you're alive, aren't you?" Therefore, whether you like it or not, you have to live. I think that mom and dad would be very happy if they knew that everything is fine with you. After all, they loved you very much ... - as cheerfully as I could, I said.
- How did you know that? The little girl looked at me in surprise.
“Well, they did a very hard thing to save you. Therefore, I think, only by loving someone very much and cherishing this, you can do this ...
– Where are we going now? Are we going with you? .. - Maya asked, looking at me with her huge gray eyes inquiringly and imploringly.
“Arno would like to take you with him. What do you think of it? It is not sweet for him either ... And he will have to get used to many more in order to survive. So help each other ... So, I think it will be very correct.
Stella finally came to her senses, and immediately "rushed to the attack":
“And how did this monster get you, Arno?” Do you remember anything...
– No... I only remember the light. And then a very bright meadow flooded with the sun... But it was no longer the Earth - it was something wonderful and completely transparent... This does not happen on Earth. But then everything disappeared, and I "woke up" here and now.
– What if I try to “look” through you? Suddenly a wild thought came into my head.
- How - through me? Arno was surprised.
- Oh, that's right! Stella immediately exclaimed. How did I not think of it myself?
“Well, sometimes, as you can see, something comes to my mind…” I laughed. “It’s not always up to you to invent!
I tried to “turn on” in his thoughts - nothing happened ... I tried to “remember” with him the moment when he “left” ...
- Oh, what a horror! Stella squeaked. “Look, this is when they captured him!!!
My breath stopped... The picture we saw was really not a pleasant one! This was the moment when Arno had just died, and his essence began to rise up the blue channel. And right behind him... to the same channel, three absolutely nightmarish creatures crept up!.. Two of them were probably lower astral earthly entities, but the third one clearly seemed somehow different, very scary and alien, obviously not earthly... And all these creatures were very purposefully chasing the man, apparently trying to get him for some reason ... And he, poor thing, not even suspecting that he was being hunted so “cutely”, soared in a silver-blue, bright silence, enjoying an unusually deep , unearthly peace, and, greedily absorbing this peace, rested his soul, forgetting for a moment the wild, heart-destroying earthly pain, "thanks" to which he ended up today in this transparent, unfamiliar world ...
At the end of the channel, already at the very entrance to the "floor", two monsters darted with lightning speed after Arno into the same channel and unexpectedly merged into one, and then this "one" quickly flowed into the main, most vile, which was probably the most powerful of them. And he attacked ... Or rather, he suddenly became completely flat, "spread" almost to a transparent haze, and "enveloping" the unsuspecting Arno, completely swaddled his essence, depriving him of his former "I" and in general any "presence" ... And then, laughing terribly, he immediately dragged the already captured essence of poor Arno (who had just matured the beauty of the approaching upper "floor") straight into the lower astral ....
“I don’t understand…” Stella whispered. – How did they capture him, does he seem so strong?.. Well, let's see what happened even earlier?
We again tried to look through the memory of our new acquaintance ... And then we realized why he was such an easy target to capture ...
In clothing and surroundings, it looked as if it had happened about a hundred years ago. He stood in the middle of a huge room, where two female bodies lay completely naked on the floor ... Or rather, they were a woman and a girl who could be fifteen years old at most. Both bodies were terribly beaten, and apparently brutally raped before death. Poor Arno "had no face" ... He stood like a dead man, not moving, and perhaps not even understanding where he was at that moment, since the shock was too cruel. If we understood correctly, these were his wife and daughter, who were abused by someone in a very brutal way ... Although, it would be wrong to say “atrociously”, because no animal will do what it is sometimes capable of human...
Suddenly, Arno screamed like a wounded animal and fell to the ground, next to the terribly mutilated body of his wife (?)... In him, as during a storm, emotions raged like wild whirlwinds - anger replaced hopelessness, rage covered melancholy, then growing into inhuman pain, from which there was no escape ... He rolled on the floor screaming, finding no way out for his grief ... until finally, to our horror, he completely calmed down, no longer moving ...
And of course - having opened such a stormy emotional "flurry", and having died with it, at that moment he became an ideal "target" for capture by any, even the weakest "black" creatures, not to mention those who later so stubbornly pursued behind him, to use his powerful energy body as a simple energy "suit" ... to do after, with his help, his terrible, "black" deeds...
“I don’t want to watch this anymore ...” Stella said in a whisper. “I don’t want to see horror anymore… Is that human?” Well tell me!!! Is this right?! We are people!!!
Stella began to have a real hysteria, which was so unexpected that in the first second I was completely at a loss, not finding what to say. Stella was very indignant and even a little angry, which, in this situation, was probably completely acceptable and understandable. For others. But it was so, again, unlike her, that only now I finally realized how painfully and deeply all this endless earthly Evil had hurt her kind, affectionate heart, and how tired she was, probably, constantly carrying all this human dirt and cruelty on my fragile, still quite childish shoulders.... I really wanted to hug this sweet, persistent and so sad little man now! But I knew it would upset her even more. And therefore, trying to stay calm, so as not to touch even deeper her already too “disheveled” feelings, I tried, as best I could, to calm her down.

I, Regotun Yury Alekseevich, entered in 1974 and in 1979 graduated from the steam power department of the Leningrad Higher Naval Engineering School named after V.I. Lenin in the city of Pushkin, Leningrad Region, specializing in steam power plants. Member of the CPSU since April 1979.

From August 1979 - commander of the machine-boiler group, from December 1982 - commander of the electromechanical combat unit of military unit 22905 (TFR "Arkhangelsk Komsomolets") of the Red Banner Northern Fleet in the city of Severodvinsk, Arkhangelsk region.

Since May 1986 - Deputy Chief Engineer of the 176th Navy Shipyard in Arkhangelsk. In 1988 he entered and in 1990 graduated from the shipbuilding faculty of the Naval Academy named after Marshal of the Soviet Union Grechko A.A., specializing in engineering, power systems of ships in Leningrad.

From August 1990 - head of the production department (ship builders) - chief builder (ships), from April 1994 - head of the production and dispatching department - head of production of the 176th Shipyard of the Navy in Arkhangelsk.

From May 1996 - deputy commander of military unit 63971 for production in the village of Danube-1, Primorsky Krai. This is 30 SRZ MO RF.

Since March 2000 - service in the central office of the Ministry of Defense of the Russian Federation as a senior officer of the repair department (Department for the operation and repair of weapons and military equipment of the Armed Forces of the Russian Federation, 17 Department of the Ministry of Defense of the Office of the Chief of Armaments of the Armed Forces of the Russian Federation). He was engaged in repair enterprises of the Ministry of Defense of the Russian Federation. He retired from the reserve in July 2008. Total length of service: 34 calendar years, preferential - 38 years.

As for the patrol ship "Mink", I remember the following. During my service, the TFR Norka was the oldest ship of our 41st division, first patrol, then anti-submarine ships. In 1980-1981. The ship was under repair at the Zvyozdochka shipyard, where it underwent major repairs and modernization. In my opinion, a significant contribution to this was made by the commander of the BC-5, Lieutenant Commander Sitaev Mikhail Nikolaevich and, probably, Lieutenant Commander Nikolai Ivanovich Mozhelev (who was in this position as commander of the BC-5 before Sitaev, but I don’t remember the time of his departure from ship). Prior to being put into repair, it was believed that the ship's hull was worn out and even a restriction on seaworthiness was introduced when the ship went to sea. The repair completely changed the situation, since the inspection and repair of the ship's hull showed its decent condition. Zvezdochka's approach to the repair of nuclear submarines made it possible to put into practice high requirements and quality for the repair of the main and auxiliary mechanisms of the ship, its pipelines and systems. Modernization has been carried out:

In the galley area, on the site of the former samovar enclosure on the starboard side, a second boiler water evaporator was installed, which largely solved the problem of replenishing water supplies on the ship;

Boat UVOs (universal air coolers) were installed in all living quarters, which, being connected to the ship’s steam heating system, made it possible to create normal living conditions for the entire crew. We adopted this experience, in particular, we installed UVO at Komsomolets in residential premises, as well as in KO and MO;

Temperature control systems were installed for the operation of the main boilers KVG 57/28, GTZA TV-9 and shaft lines;

Salinometers were installed to measure the salinity of feed water;

New condensate level regulators were installed in the main refrigerators GTZA TV-9 instead of RUK-1.

There were other technical "jokes", but I described the main ones that I remember.

After leaving this repair, the ship passed without major repairs until the next repair in 1986-1987. at SRZ 176 (then still a Navy plant, and then the Russian Ministry of Defense), which was its last repair before being withdrawn from the combat strength of the USSR Navy. I was engaged in this last repair of "Mink" from the side of the plant. The builder of the order was the builder of warships Grishchenko Alexander Mikhailovich, who provided the organization of the repair.

From the time spent on the "Mink" I remember two things:

1) when entering the sea, the line for supplying saturated steam to the second "boat" evaporator cracked. The pipe was made of stainless steel and improvised, i.e. With conventional electrodes and the efforts of the craftsmen of the BCh-5, we could not brew it. As a result, instead of an additional two tons of condensate per hour, we had a serious loss of feed water from the steam-condensate cycle. As a result, the evaporator was stopped and further IKV water was continued to be boiled in the auxiliary mechanisms compartment. Replenishment of water supplies was difficult for us. since the BS-5 navigation watch was used to the fact that feedwater was supplied in more than sufficient quantities. Upon returning to the base, the defect was eliminated with the help of a floating workshop. After returning from vacation, Misha Sitaev received a serviceable material part and kept making fun of me. Like, how did you manage to have problems with water, having two evaporators ...

2) at night, after the divorce of the navigation watch, I went to rest in cabin No. 1. After a while, a messenger woke me up: "Comrade senior lieutenant! The ship is standing still ...!" I look at the pressure gauges in the main boilers - the norm, I look at the tachometers for the revolutions of the shaft lines - the average stroke. All these instruments were installed on the aft bulkhead of the cabin and were clearly visible in the supine position. I was very surprised, brought the body to a vertical position and went to the waist. Exactly, we are standing, although the cars are working "Medium Forward". Climbed to the navigation bridge and saw a cheerful picture. The ship rested its stem against a hefty ice floe and stands ..., conscientiously working with propellers. Of course, the situation was corrected by a change in course. And the watch officer became the hero of this watch, I don’t remember who it was. He decided to spit overboard, which he did. However, its powerful spit did not fly away towards the stern, as usual, but disappeared along a trajectory perpendicular to the diametrical plane of the ship. This fact was of great interest to the watch officer, which was the reason for restoring the movement of the ship on a given course!

Developed on the personal instructions of I.V. Stalin for sentinel service and protection of small coastal convoys. Chief designer of the project initial stage design was D.D. Zhukovsky, then (in SKB-194) - V.I. Neganov, and from the end of 1953 - B.I. Kupensky, and captain 1st rank V.S. was appointed observer from the Navy. Avdeev.

The hull of the ship is smooth-deck, made by electric welding, except for the connection of the sheerstrake with the deck stringer and removable sheets, with a significant sheer in the bow with one tripod mast and two superstructures. The bow formations of the hull along the waterline were distinguished by a significant sharpening, and the frames were carried out with collapse near the upper deck. High-strength low-alloy steel grade SHL-4 and armor grade 48PM were used as the main body material. The hull was assembled according to the longitudinal scheme, with the installation of frame frames, floors and beams through 2-3 spacings (1000-1500 mm). Boiler and engine rooms in the area of ​​79.5-117.5 sp. along the sheerstrake and two subsequent belts of the outer skin, the wheelhouse, body kits of the navigation bridge and shields of artillery installations were protected by anti-fragmentation armor 7-8 mm thick. All combat posts and premises, with the exception of the bomb cellar No. 6, the midshipman's compartment and the steering compartment, were provided with access without leaving the personnel to the upper deck. The rank and file and foremen of the military service (147 people) were located in five bow and one aft cockpits. Ten officers were accommodated in 7 cabins. There were 4 spare places in the officer cabins to accommodate the flagship specialists. For 10 midshipmen, they equipped 3 cabins and their own wardroom.
The unsinkability of the ship was ensured by division into 11 watertight compartments:

1. Forepeak, skipper, painting and rigging pantries (0-7 frames);
2. Chain box, cockpit No. 1 for 10 people, locker room, bathhouse, latrine and washroom, vestibule No. 1, electromechanical pantry, pantry for wet provisions and refrigeration chamber, POU GAS compartment (7-30 frame);

9. Kubrick No. 6 for 38 people, cellar No. 4 and No. 5 of artillery ammunition, fuel tanks, stern tube corridors (129-144 frames);
10. Corridor No. 2, midshipmen's cabins, infirmary, pantry of medicines, latrines, midshipmen's wardroom, ventilation enclosure, anti-submarine ammunition cellar, cofferdam, fuel tanks (144-162 frames);
11. Bomb releaser control post, tiller compartment, fuel tanks (frame 162-174).

According to calculations, the ship should have remained afloat when any two adjacent compartments were flooded, provided that the compartments adjacent to the flooded compartments were kept "dry".

The power plant is mechanical, two-shaft, boiler-turbine with two turbo-gear units (GTZA) TV-9 with a capacity of 10,000 hp each. and two water-tube boilers arranged in a linear pattern. The TV-9 units had the ability to start turbines from a cold state and were placed side by side in the engine room.
The main boilers - water-tube, small-sized KVG-57/28 with blast into the furnaces, with a working pressure of superheated steam of 28 kg / cm2 and a temperature of 3700 ° C, were located on board in the boiler room.
The auxiliary boiler provided steam for ship mechanisms and the economic needs of the ship as a whole.

The alternating current electric power system with a voltage of 220 V, 50 Hz was powered by two turbogenerators (TG) with a capacity of 150 kW each and had one diesel generator with a capacity of 100 kW and one standby diesel generator with a capacity of 25 kW.

The armament of the ships consisted of:

1. Of 3 single-barreled 100-mm B-34USMA guns with a barrel length of 56 calibers. There were two guns in the bow and one in the stern of the ship. Ammunition consisted of 200 rounds per gun. The installation had a shield made of bulletproof armor and an original design of a movable shield covering the embrasure. The rate of fire with mechanical loading was 15 rds / min. The initial velocity of the projectile is 900 m / s, the maximum elevation angle is 85 ° and the firing range is 22 km, the ceiling is 15 km. Calculation - 7 people. The vertical and horizontal pickup mechanisms ensured a guidance speed of up to 12 degrees / s. The mass of the installation is 12.5 tons, the survivability of the trunks (with phlegmatizers) reached 1500 shots. The aiming of the gun mounts was carried out automatically using remote control and manually. For remote control of the firing of 100-mm artillery, a stabilized rangefinder post SVP-42-50 was installed, combined with the Anchor radar antenna and the Sfera-50 control system (CS).
2. Of 2 twin 37-mm B-11 assault rifles with a barrel length of 67 calibers, located on the side in the stern of the ship, to combat aircraft. Clip loading (5 shots per clip), clip feeding manually. The calculation of the gun included 11 people. The rate of fire of the installation was up to 360 shots / min. Elevation angle from -15 to +90°. Drives vertical and horizontal guidance only manual. The initial velocity of the projectile is 880 m / s, and the firing range is up to 8.4 km, the ceiling is 4 km. The aiming of the gun mounts was carried out by the automatic sight AZP-37-2M. The mass reached 3,400 kg.
3. From 1 three-pipe 533-mm torpedo tube TTA-53-50 with ammunition from 3 linear steam-gas torpedoes 53-51 in TA. The torpedo tube was completed with a central device for firing control. Later, with the advent of anti-submarine torpedoes, SET-65 torpedoes were also used.
4. From mine rails and 26 anchor mines KB-3 to overload. The ship's large mine with a galvanic impact fuse weighed 1065 kg, and the weight of the charge was 230 kg. The depth of the setting ranged from 12 to 263 meters, the minimum mine interval was 35 meters, the highest speed when setting was 24 knots with a side height of 4.6 meters. The time to enter the combat position was 10-20 minutes, the accuracy of installation on a given recess was 0.6 meters, the explosion delay was 0.3 seconds.
5. From 2 bombers and depth charges BB-1. The total weight of a large depth charge was 165 kg, and the weight of TNT was 135 kg with a length of 712 mm and a diameter of 430 mm. The immersion speed reached 2.5 m / s, and the radius of destruction ranged from 8 to 20 meters. The bomb provided the setting of the depth of the explosion from 10 to 210 meters.
6. From 1 MBU-600 jet bomber with 24 guides and the ability to change the guidance angles of each, it was fixedly fixed in the bow of the ship and stabilized during rolling. Aiming at the target was carried out by the ship's hull along the course. The bombing was fired in one gulp, and the fire was controlled from the wheelhouse using the PUS-24-600 fire control device. The ammunition included 120 B-30 depth charges. The firing range was 644 meters, and the impact zone of a submarine traveling at a speed of 10 knots at a depth of up to 330 meters was elliptical, due to the individual inclination of the guides, 30-40 meters along the direction of fire and 40-50 meters wide. B-30M bombs were used.
7. Of 4 single-barrel bombers BMB-2, located side by side in the stern. The bombers have a caliber of 430 mm, a firing range of 120 meters and a depth of destruction of up to 330 meters. Bombers use BB-1 bombs.

The fire control system of the universal 100-mm artillery consisted of:

• From the artillery fire control device (PUAO) "Sphere-50" which included:
• automatic firing machine (calculating device), which, based on the incoming data from the stabilized sighting post SVP-42-50, combined with the Anchor tracking radar antenna, gave out vertical and horizontal aiming angles of universal 100-mm caliber installations.
• remote control system SSSP-50.
• gyro stabilization system "Component", which ensured the stabilization of 100-mm caliber gun mounts during pitching.
• The target was detected by an optical rangefinder (only surface) or target designation radar "Guys-1M" (air, surface and coastal).
• Then the target was taken for escort of the "Anchor" firing radar (range measurement using the radar, its heading angle - with an optical sight).

The Yakor tracking radar of the decimeter wave range made it possible to determine the range and track air, surface and coastal targets to control the firing of 100-mm caliber universal artillery. The radar automatically tracked air targets at ranges up to 30 km, and surface targets up to 33 km.

The ships were equipped with the Guys-1M target designation radar, the Lin navigation radar, the Fakel state identification equipment, the Pegasus-2 GAS, the ARP-50 radio direction finder, the Tablet-50 BIUS, and MDSh smoke bombs.

The Guys-1M target designation radar was designed to detect surface and air targets and issue target designation to the fire control systems of artillery of universal and anti-aircraft calibers of small ships. The station operated in the meter wavelength range with a radiation power of 80 kW and provided circular and sector search, as well as target tracking with determination of the distance, its course angle and bearing. Two antennas of the "wave channel" type were placed on the mast, radiation and reception could be carried out both on both antennas, which worked in phase, and on one. The main radar units weighing 174 kg were placed on the deck of the ship. The target detection range of the cruiser-type station was up to 11 km, the destroyer - up to 8 km, the minesweeper - up to 6.5 km, and the errors in determining the azimuth - 1.5 °, range - 92.5 meters.

The Lin navigation radar operated in the decimeter wave range, and also had three modes of operation - all-round visibility for navigation purposes, sector search and tracking of surface and low-flying air targets. The parabolic type antenna was placed on the mast.

The state identification system is represented by two RAS - the interrogator and the respondent "Fakel". RAS "Fakel" allows you to identify surface and air targets to determine their belonging to their armed forces. Two antennas are located on the mast.

GAS "Pegasus-2" with a wing antenna, which worked in echo and noise direction finding modes. The GAS was capable of detecting a submarine going at periscope depth at a distance of 2.6 km, and anchor mines at a distance of 1.3 km, at a speed of the TFR itself of up to 20 knots.

The direction finder ARP-50 was designed to determine the location by radio beacons in dark time days and in poor visibility. The antenna (frame) of the radio direction finder was placed on the mast. The direction finder worked in the range of long and medium waves.

CICS "Tablet-50" is a combat information and control system designed to coordinate the work of shipborne environment lighting, display it on tablets, process information, and determine the elements of target movement. At the same time, simultaneous processing of data on 4-5 surface and 7-9 air targets was ensured.

Marine smoke bomb MDSH with a smoke generator from a solid smoke mixture based on ammonia and anthracene. With a length of 487 mm and a mass of 40-45 kg, its operation time is eight minutes, and the smoke screen created reaches 350 meters in length and 17 meters in height.

Ships were built at plant No. 445 in Nikolaev (20), at plant No. 820 in Kaliningrad (41) and at plant No. 199 in Komsomolsk-on-Amur (7).

The lead "Ermine" entered service with the Black Sea Fleet in 1954.

The First World War revealed the need to create another class of light ships - patrol ships with the purpose of protecting ships and transports at sea from submarine attacks, torpedo boats and aircraft, carrying out sentinel service, and actively supporting the actions of ground forces in skerry areas. In the Russian Navy, the issue of designing patrol ships was raised already in 1924. Design studies showed that in order to carry out the assigned tasks, such ships must have a speed of about 30 knots, an economic cruising range (16 knots) of about 1500 miles, and carry torpedo weapons , depth charges, artillery installations with a caliber of about 100 mm, anti-aircraft artillery and machine guns. Already by 1927, the technical design of the Hurricane-class patrol ship (later it was assigned No. - Project 2) was developed and approved. These were the first warships designed and built under Soviet rule. The total displacement of the ship was 534 tons, length 71.5 m, speed 25.8 knots, armament 2 x 102 mm, 4 x 45 mm gun mounts, one 3-tube 400 mm torpedo tube, crew - 101 people. In 1927, 8 units were laid. ships of the project, of which 6 units. in Leningrad, 2 units. in Nikolaev. Subsequently, the design of the ship was corrected twice and successively received Nos. 4 and 39. At the same time, there were no significant changes in the project. On pr. 4 in Leningrad and Nikolaev, 4 units were laid. ships (SKR "Metel", "Vyuga", "Thunder", "Burun"). In disassembled form, these ships were transported to Vladivostok and assembled there at Dalzavod. These ships subsequently became part of the created OVR formation. According to project 39, again in Leningrad and Nikolaev, 6 units were laid. of which 2 units. (TFR "Lightning", "Zarnitsa") were transported disassembled and assembled at Dalzavod. In total, until 1938, 18 units were built. patrol ships of this type, 8 units. of these, the ships of the Pacific Fleet were killed. In 1937, the leadership of the Navy issued a tactical and technical assignment for the design of a patrol ship that was larger, faster, more heavily armed than the Hurricane type. Project 29 became such. The total displacement of the ship of the new project reached 995 tons, length - 85.7 m, speed 34 knots, cruising range (15 knots) 2700 miles, the number of guns of the main caliber (100 mm) brought to 3. Before the start of the war, 14 units were laid at 3 plants under this project. ships (in Leningrad at plant No. 190 - 8 units, in Nikolaev at plant No. 198 - 4 units, in Komsomolsk-on-Amur at plant No. 199 - 2 units). In total, a series of 30 units was supposed. Before the start of the war, 3 units were launched. With the outbreak of war, the construction of the ships of the project was suspended. During the war years, only one ship was completed.
The requirements arising from the experience of the war, as shown by the studies performed, were not fully met by those under construction patrol ships etc. 29. Nevertheless, 6 units. according to the corrected project 29K in 1947-51. were completed (two by plant No. 199 in Komsomolsk-on-Amur (SKR Albatross, Burevestnik), two by plant No. 190 in Leningrad, two by plant No. high requirements for patrol ships.First of all, it became necessary to give them high seaworthiness, ensuring safe navigation in any sea state, with the ability to use weapons in seas of 5-6 points. against sea and air targets, equipping with rapid-fire anti-aircraft guns, means of remote automatic control of artillery fire using radar for detecting surface and air targets. bombo metov. It turned out to be impossible to achieve the necessary improvement in the performance characteristics of the skr based on Project 29 with a more radical revision of the project, and a decision was made to design a new ship. They became project 42. On the basis of the operational-tactical task of the Navy, two design bureaus - TsKB-32 and TsKB-53, developed a pre-draft project on a competitive basis. The design was carried out in 2 versions - with a diesel and steam turbine installation. TTZ for the design, developed by the Navy on the basis of pre-draft designs, was approved by the Decree of the Council of Ministers of the USSR on June 27, 1947. The design was entrusted to TsKB - 32 in Leningrad. Chief designer Zhukovsky D.D., Chief Observer from the Navy Captain 1st Rank Sagoyan A.P. The technical design was approved already in December 1947. For the first time in the domestic fleet, a ship of this class received a smooth-deck architecture, and the propellers and two rudders did not protrude beyond the main plane, which ensured comparative safety of navigation on shallows and in estuaries. The standard displacement of the ship was 1,339 tons, the total displacement was 1,679 tons. It should be noted that the displacement of the new skr was only 400 tons less than the displacement of the destroyer of the pre-war construction of project 7, its width was commensurate with the width of the em, but it was 16 m shorter in length (96.1 m). All TTZ requirements in the project were met. The purpose of the patrol ship was to escort convoys, carry out sentinel service, participate in landing operations and lay minefields. To accomplish these tasks, the ship had the following tactical and technical elements:
- full speed 29.6 knots, cruising range at a combat economic speed of 14 knots up to 2810 miles (instead of 2000 miles stipulated by the assignment);
- GEM steam turbine, two-shaft, the location of the GEM is echelon (in 4 compartments - in two boiler rooms and two engine rooms, as a result, the ship became two-pipe), main boilers KV-42, main turbo-gear units (GTZA) with a capacity of 14000 hp each. each;
- the ship's electric power system (EESK) on alternating current, 220 V, 50 Hz (for the first time in domestic shipbuilding on serial ships), with a total capacity of 550 kW (two turbogenerators (TG) of 150 kW, two diesel generators (DG) of 100 kW , one parking diesel generator 50 kW);
- artillery armament consisting of 4 single-gun 100 mm B-34USM universal mounts with a fire control system, 4 37 mm machine guns in 2 twin V-11 mounts;
- torpedo armament included one 3-tube torpedo tube for torpedoes with a caliber of 533 mm;
- bomb armament consisted of 4 BMB-1 bombers (later replaced by RBU-2500), and two stern bomb releasers;
- radar and hydroacoustic weapons included the radar for detecting surface and low-flying air targets "RIF", the radar for detecting air targets "Guys-1MN", the sonar for detecting the submarine "Tamir-5N".

The lead ship of Project 42 of the TFR "Sokol" was laid down in Kaliningrad at plant No. 820, based on the German plant "Shihau", restored as soon as possible after the war, on August 17, 1949, launched on September 11, 1950, accepted to the Navy on June 29, 1951. In total, until 1953, this plant built the entire series of 8 units. The ships became part of the Northern Fleet - 6 units, and the Baltic Fleet - 2 units. Subsequently 3 units. ships of the project from the Northern Fleet were transferred to the Caspian Flotilla and were transferred to the Caspian Sea via inland waterways.
In 1949, the development of a new project 44 patrol ship with 100-mm artillery in two deck-turret mounts, with 45-mm machine guns in 2-quad stabilized mounts and 25-mm machine guns in 2-quad unstabilized mounts was considered. According to the calculations made in the preliminary design, the standard displacement of the ship was already more than 1600 tons. This was commensurate with the displacement of the destroyer pr. 7.
When the government considered the issue of creating patrol ships of project 42 (and even more so project 44) and organizing their construction in a large series, their displacement was recognized as unacceptably large. It was decided to limit the series of ships of Project 42 to 8 units, despite the prospects of the ship, confirmed positive results, obtained in 1951 during the tests of the lead ship of the Sokol TFR. There are quite a few reasons for refusing the large-scale construction of these ships, and first of all, the decision of the Chairman of the Council of Ministers of the USSR I.V. Stalin. This decision had many reasons. Some of them did not find documentary evidence and remained only in fragmentary memoirs of the leaders of the Navy and industry of those years. First of all, the evolution of views on the part of the military and political leadership of the country continued. The question arose again, to which there was no clear and unambiguous answer at that time: “What convoys were supposed to guard these ships? When the development of the economy of the USSR in the post-war years was again focused on "all-round defense against the imperialists and the complete autonomy of the state." Smaller ships were required to carry out sentinel service and protect small coastal convoys. According to I.V. Stalin, the new patrol ship should have a displacement of 1000 - 1100 tons, and preferably 900 tons, and be intended for border and intelligence services. Stalin regarded the desire of the Navy to get a larger patrol ship as "monkey", pointing out that one should not copy the Americans and the British, who have raw material bases overseas and therefore really need a patrol ship capable of accompanying transports on long ocean crossings. As a result, on the personal instructions of I.V. Stalin began the development of TTZ for a new patrol ship with a total displacement of 1200 tons of project 50.
On June 20, 1950, the Council of Ministers approved the task for the development of a new project 50 patrol ship. In the task, the total displacement of the ship was strictly limited to 1200 tons. To reduce the displacement, even the requirement for an economic cruising range was reduced to 1000 miles. Artillery armament was simplified by the installation of deck-mounted unstabilized 100-mm guns, the same as on skr pr. 42. The Council of Ministers of the USSR ordered the Ministry of the shipbuilding industry and the Naval Ministry to develop the skr project 50 and build the lead ship within the following timeframes:
- complete the development of a draft design in September and submit it to the Council of Ministers in October 1950;
- complete the development of the technical project in February and submit it to the Council of Ministers in March 1951;
- start building the lead ship in the 2nd quarter of 1951 and present it for state tests
In the 3rd quarter of 1952
The design of the patrol ship pr. 50 was started by a special design bureau of the Ministry of the shipbuilding industry in Leningrad. Then, in March 1952, the technical documentation of the project and part of the design personnel were transferred to Kaliningrad to the design bureau at shipbuilding plant No. 820. Zhukovsky D.D. was the chief designer of the project at the beginning, then Neganov V.I. designing since the end of 1953 - B.I. Kupensky. The captain of the 1st rank Avdeev V.S.
Naturally, project 42 was taken as the basis for the project. In July-August 1950, various technical issues were coordinated that would make it possible to obtain the given displacement and the necessary seaworthiness and combat qualities of the ship. However, in the given dimensions, it was not possible to fully fulfill the requirements for wind resistance. The conducted studies have shown that it is possible to provide a given displacement only with a linear placement of the main power plant (MPP), i.e. two main boilers (GK) on board in one compartment (boiler room), two main turbo gear units (GTZA) on board in another adjacent compartment (engine room), which naturally reduced the survivability of the power plant and the ship as a whole. In the process of ongoing research, a scheme was also considered from two engine-boiler rooms (MCBs), i.e. in one compartment GK and GTZA. After numerous disputes, they settled on the linear arrangement of the power plant. During the design, serious attention was paid to achieving high seaworthiness. To this end, a large amount of research with testing of various options for shaping the hull on models was carried out in experimental pools. The forms of the nasal contours of the hull were carefully worked out at the Central Research Institute - 45. The nasal formations of the hull were significantly pointed compared to Project 42. All this ultimately led, as it was found out during the tests of the lead ship of the project, to better seaworthiness, in terms of flooding and splashing in waves, compared with skr pr. 42 and destroyers pr. 30bis, which had a large displacement. It should be noted that due to the intensive flooding of the splashing of the bow of the ship near skr 42, in a wave of more than 4 points, the use of weapons was significantly hampered. During the tests of the lead ship of the project, it was also noted that the vibration of the aft end of the hull, again, decreased significantly compared to the skr pr. 42 and destroyers pr. 30bis. On skr pr. 42, due to increased vibration, it was even necessary to strengthen the aft part of the hull. The ship, like skr pr. 42, had two rudders, but the propellers, due to the large diameter (speed reduction), protruded beyond the main line, which worsened the conditions for passage through inland waterways and made it more dangerous to navigate in the shallows and at the mouth of rivers. However, the ship had a smaller draft.
During the design Special attention also addressed to reduce the weight and size characteristics of weapons, weapons, equipment, again in order to meet the specified displacement. While ensuring high combat and operational qualities of the ship. So it was supposed to replace two bow 100-mm B-34 USM artillery mounts with one twin closed-type mount with the same 100-mm guns. The development of such an installation was then carried out in OKB - 172. Attempts were also made to replace the MBU - 200 with the MBU - 600 and 37 mm machine guns with 25 mm. But still, the final composition of the ship’s armament differed from Project 42 only by a decrease in the number of 100-mm B-34 USM gun mounts from 4 to 3, the number of torpedo tubes (TA) from 3 to 2, and a decrease in artillery ammunition by 15%.
The draft design was completed on time. In the process of its consideration by the Acting Minister of the Navy, Admiral Golovko A.G. approved a proposal to replace 4 BMB-1s with 4 BMB-2s. The standard displacement obtained in the preliminary design was 1,059 tons. The technical project was also completed on time. In it, the standard displacement increased to 1,069 tons. Due to the additional free volumes in the double-bottom space obtained on the ship during the design, even with the existing standard displacement, it became possible to take in them almost twice as much fuel (at the highest displacement), an additional 120 tons in overload, and thereby bring the cruising range to almost 2 000, i.e. twice as much as it was envisaged by the design task. The presence of only a two-pipe HE instead of the traditional three-pipe was constantly criticized. When approving the technical design, it was decided to oblige SKB-700 SMEs, by order of the MTU of the Navy, to develop in 1951 a technical design of a three-tube TA in relation to the ships of project 50. Subsequently, these devices were developed and installed on the ships of the project.
The hull of the ship was made the same as that of the project 42, smooth-deck, but with even greater longitudinal sheer in the bow, it was single-tube, with one mast and two superstructures. For all combat posts and premises, with the exception of the bomb cellar No. 6, the midshipman's compartment and the steering compartment, located in the stern of the ship, a closed passage was provided, which was unusual for such a small ship and ensured the safety of personnel moving around the ship in stormy conditions. The entire hull was electro-welded, with the exception of the connection of the upper deck with the side and removable sheets. Subsequently, during tests, the overall and local strength of the hull were found to be quite satisfactory. Anti-fragmentation armor 7-8 mm thick was reserved for the power plant compartments, the wheelhouse and the shields of the artillery mounts.
For the power plant of the project 50 ship, boilers of the new type KVG - 57/28 with blast into the furnaces were developed at SKKB, when the type KV - 42 was used on project 42 with fan blast into closed boiler rooms. The steam parameters were identical: working pressure - 28 kg/cm2, superheated steam temperature 3700C. The dimensions of this type of boiler were smaller compared to the boilers installed on the ships of Project 42, and this made it possible to place two boilers in one boiler room. Looking ahead, it should be noted that the new design scheme of the ship's boiler was the basis for the creation of highly accelerated small-sized boilers for all classes of surface warships of subsequent construction. The problem of the subsequent high forcing of the furnace with an increase in its thermal load by 3 times was also solved. GTZA of a new type TV - 9 was also used on the project. GTZA TV - 9 was a single-case active-reactive single-flow turbine with a capacity of 10,000 hp, a single-flow surface condenser located along the axis with a power split. TV - 9 could be put into operation from a cold state, which significantly reduced the time for commissioning the power plant. During the period of state tests of serial ships, breakdowns of turbine blades were found. A special commission chaired by Professor Grinberg M.I. I found out that the specified breakdown occurs due to resonant vibrations at full forward and reverse speeds. On this issue, the Council of Ministers of the USSR in April and September 1954 adopted resolutions on the correction of these defects. In this regard, a temporary limitation of the maximum speed to 25 knots was introduced. The restriction was lifted in 1955. On sea trials, the ship reached full speed with a normal displacement (50% of fuel, water) of 29.5 knots at 386 rpm propellers. Despite the reduction in propeller speed compared to project 42, it was not possible to avoid erosion on the suction sides of the blades at the propeller hubs.
The electrical power system of the ship was adopted on alternating current with a voltage of 220 V, a frequency of 50 Hz. The total power of EESK was 425 kW. It included two turbogenerators (TG) with a capacity of 150 kW each, one diesel generator (DG) with a capacity of 100 kW (diesel 7D6), one parking G with a capacity of 25 kW.
According to the project, three 100-mm single-barreled universal deck artillery mounts of the B-34USMA type were installed on the ship, two in the bow and one in the stern, with a firing range of 22 km., An altitude reach of 15 km, a rate of fire of 15 rounds per minute, 200 shots in the cellar. The aiming of the gun mounts was carried out automatically using remote control and manually. It was the first domestic universal installation with automatic remote control from a rangefinder post. To control the firing of 100-mm artillery, a stabilized rangefinder post SVP-42-50 was installed, combined with the radar antenna of the Anchor control system, the Sfera-50 control system (CS). The Yakor radar had a range of 180 kbt for a sea target, and up to 165 kbt for an air target. In the future, the Yakor radar was changed to the Yakor-M2 radar. As anti-aircraft artillery, the 4th 37-mm machine gun was installed in two twin V-11 artillery mounts, with a firing range of 8.4 km, a height reach of 4 km, a pace firing 360 rounds per minute and autonomous guidance.
As a torpedo armament on the ship, the project provided for the installation of one 3-pipe TA with an ammunition load of 3 533-mm torpedoes in an apparatus with a fire control system from a central device. TA was intended for firing only with straight-line steam-gas torpedoes 53-38, 53-39, 53-39U, 53-51. Later, with the advent of anti-submarine torpedoes, SET-65 type torpedoes were used.
As an anti-submarine weapon on the ship, the project provided for the installation of an MBU-600 bombing mount with 24 guides in the nose (B-30M bomb, with a firing range of 644 m, a depth of destruction of 330 m). Later, during upgrades under the 50PLO project, it was replaced by two 16-barrel rocket launchers of the RBU-2500 type (RGB-25 bomb, caliber 213 mm, with a firing range of 2.8 km, a depth of destruction of submarines of 330 m.), with a remote control and placed in the bow of the ship on board. In the stern of the ship, the 4th 1-barrel BMB-2 bomber was installed (BB-1 bomb, caliber 430 mm, with a firing range of 120 m, a depth of destruction of the submarine 330 m.). Later, with the installation of RBU-2500, they were dismantled. In the stern of the ship, there were two stern bombers on board.
As a radio-technical armament of weapons on the ship, the project provided for the installation
GAS "Pegas - 2" with a wing antenna, which was one of the GAS of the 1st generation, operating in echo and noise direction finding modes and having a detection range of up to 2 - 3 km. In tests, it was found that at speeds up to 20 knots, this sonar was capable of detecting software located at periscope depth at a distance of 14 kbt (2.6 km), and anchor mines at a distance of 7 kbt. Already in the course of construction, GAS Pegasus-3M and Hercules were installed on ships of a later build. As a navigation radar, it was planned to install the Lin radar, which made it possible to detect surface targets at ranges up to 25 km. As a radar for detecting surface and air targets, it was planned to install the Gyuys-1M4 radar with a detection range of surface targets up to 8-10 km, air targets - up to 40-50 km. Later, instead of this radar, a more effective Fut-N radar was installed with a detection range of up to 25 km, airborne - up to 50 km. A combat information system (CICS) "Tablet-50" was also installed on the ship of the project, which was intended to coordinate the work of shipborne means of illuminating the situation, displaying it on tablets, processing information, and determining the elements of movement of targets. At the same time, simultaneous processing of data on 4-5 surface and 7-9 air targets was ensured.
As navigator's weapons, communications equipment, the models of equipment adopted at that time for service in the Navy were installed.
The unsinkability of the ship was ensured by its division into 11 watertight compartments. According to the calculations, the ship had to remain afloat when any two adjacent compartments were flooded, provided that the compartments adjacent to the flooded ones were kept “dry”. In this case, the stability of the ship will always be positive (h > 0). It is most dangerous to receive damage by a ship in standard displacement, because. with this displacement, the ship has the least stability. The results of calculations of the most dangerous cases of damage showed that the ship pr. 50 has a relatively high unsinkability and remains afloat, maintaining positive stability when flooding in some cases more than 2 adjacent compartments. So the ship stays afloat, maintaining positive stability at:
- flooding of 4 adjacent compartments in the region of 0 - 59 frames and the presence of seepage water on lower deck in the region of 59 - 80 ws;
- detachment of the bow to the bulkhead 59 sp and the presence of seepage water in the hold in the area of ​​59 - 80 sp .;
- flooding of 3 adjacent compartments in areas 30 - 80, 80 - 129 sh;
- flooding of 4 adjacent compartments in the area of ​​59 - 129 sp., but only at full displacement;
- flooding of 3 adjacent compartments in areas 129 - 172, 117 - 162 sht;
- separation of the aft end to the bulkhead 129 sp.
The death of the ship from the loss of stability (its capsizing) could occur when:
- separation of the bow to the bulkhead 59 sp. and asymmetric flooding of 2 adjacent compartments in the area of ​​​​59 - 96 sp. and in the absence of fuel in spare tanks;
- sharply asymmetric flooding of 4 adjacent compartments in the area of ​​​​59 - 129 sp. with standard displacement;
- asymmetric flooding of 4 adjacent compartments in the area of ​​117 - 172 sp. with standard displacement;
- separation of the aft end to the bulkhead 129 sp. and asymmetric flooding of 2 adjacent compartments in the area of ​​​​96 - 129 sp..

A comparison of the skr pr. 50 of the first series with foreign analogues shows that if our skr surpassed them in driving performance, then it was significantly inferior in cruising range. This is explained by the fact that our skr was not intended to escort ocean convoys. Integral assessment of weapons shows that skr pr. 50 was at the level of the tkr "Butler" of the US Navy built during the 2nd world war, but inferior to the tkr "Dili" built in the 50s. In terms of artillery, if we consider only the firing range and the magnitude of a minute salvo, then our skr was superior to its counterparts, however, their turret installations made it possible to use artillery in conditions of more intense splashing and unrest. Finally, the automatic 76-mm gun mounts of the TFR "Dili" were much more effective when firing at air targets. In terms of anti-submarine weapons, the superiority of the Dili SKR was significant, because its torpedo tubes used already homing anti-submarine torpedoes, the Mk108 jet bomber had an effective firing range of 2.5 kbt, the GAS had a detection range of more than 30 kbt. Later, during the modernization of the skr on pr. 50PLO, anti-submarine weapons and their means of support began to correspond to that time and the ship, in its capabilities, caught up with foreign counterparts.
The construction of project 50 patrol ships was deployed at three shipyards: No. 445 (later the Kommunar plant 61) in Nikolaev, No. 820 (later the Yantar plant) in Kaliningrad and No. 199 (later the Lenin Komsomol plant) in Komsomolsk-on-Amur.
The lead ship of the project 50 TFR "Gornostay" was laid down on the slipway of plant No. 445 (later plant named after 61 Kommunar) in Nikolaev on December 20, 1951, launched on July 30, 1952 and accepted into the Navy after lengthy tests of only 30 - July 1954
In total, until 1959, 68 units were built. project ships. After the destroyers of project 30bis (70 units), it was the second largest series of ships in the domestic fleet, with a displacement of more than 1000 tons. The entire series was built, in fact, in 7 years, starting from the moment the lead ship was laid down, and the delivery of the entire series to the Navy was within 5 years. At the same time, 20 units. was built at plant number 445 (delivery from 1954 to 1956), 41 units. at plant No. 820 (delivery from 1954 to 1959), 7 units. at plant number 199 (delivery in 1954). The construction was carried out by the method of large-scale mass production. The technology of block formation of buildings was applied with the saturation of each block in specialized workshops of factories. The ship was eventually assembled on a slipway of five separate blocks delivered from the workshops of factories via a specially constructed transportation system. As a result, the construction time of the ships was significantly reduced. The construction period of serial ships from laying to the delivery of the Navy took an average of only 10-12 months, and for individual ships only 4-6 months. The intensity of the construction of the ships of the project and the pace of replenishment of the fleet with new ships in those years are impressive. Annually surrendered to the fleet by each plant from 6 to 8 units. ships, etc. 50. So in 1954, plant No. 820 delivered 9 units to the fleet, plant No. 445 - 8 units, plant No. 190 - 7 units. Larger ships were built just as intensively in those years - project 30bis destroyers, the construction period of which was 14-18 months. The delivery of the ships of this project by four shipyards reached 20 units. in year. Including the Far Eastern Plant No. 199, in some years, it delivered 5-6 units to the Navy. project ships. Here we no longer have to talk about submarines and ships of smaller displacement.
Ships were assigned to all fleets. The Northern Fleet was initially credited with 15 units. ships of the project, to the Baltic - 16 units, to the Black Sea - 18 units, to the Pacific - 19 units. For the Pacific Fleet, in addition to 7 units. ships pr. 50 built by plant No. 190 (SKR Zubr, Bizon, Stork, Weasel, Pelican, Penguin, Cheetah) until 1959 another 12 units were transferred by the Northern Sea Route . ships built by plant No. 820 (SKR "Lun", "Los", SKR - 54, - 55, - 50, - 59, - 60, - 61, - 62 (later "Irkutsk Komsomolets"), - 74, - 75, - 4, - 10. B different time patrol ships of Project 50 were part of various formations of the Pacific Fleet: 173 brem (destroyer brigade, Petropavlovsk - Kamchatsky), 174 brem, 196 brkovr (Sovetskaya Gavan), 201, 202 brplk, 47 brkovr, 45 brkovr (Primorye). Later, from the composition of the Northern, Baltic and Black Sea fleets, one skr of the project moved to the Caspian Sea and became part of the Caspian Flotilla. 16 units ships of the project were eventually transferred to the Navy of foreign states: the Indonesian Navy - 8 units. (from the Pacific Fleet 4 units: TFR "Bison", "Bizon", "Aist", "Pelican"), the Navy of the German Democratic Republic - 3 units, the Bulgarian Navy - 3 units, the Finnish Navy - 2 units. The construction of the ships of the project was carried out in China according to the technical documentation transferred by the USSR.

In the course of their service, Project 50 patrol ships demonstrated sufficiently high operational and seaworthiness qualities, were quite easy to manage and maintain. The habitability conditions satisfied the crews sufficiently. The ships of the project, despite the autonomy limited to only 5 days in terms of feed water and fuel reserves, were involved in the performance of combat service tasks. Basically, the tasks of combat service in the Mediterranean Sea as part of 5 operations teams and in the Indian Ocean regions as part of 8 operations teams were carried out by patrol ships of the project from the Black Sea Fleet.
Patrol ships of the Pacific Fleet performed the tasks of combat service in the area of ​​the Korea Strait. They were also involved in tasks in more remote areas. So TFR - 54 from the 29 dnplk 45 brkovr (Vladimir Bay) in 1981 performed tasks in the South China Sea (Kamran). At the same time, transitions to the area of ​​​​combat service and back were carried out on their own.
Project 50 patrol ships operated in fleets until 1990. Most of the project ships served in the fleet for more than 30 years. The ships of the project, which were part of the Pacific Fleet, were operated until 1989. TFR "Laska" (built in 1954) was excluded from the combat strength of the Pacific Fleet in 1981 by order of the Civil Code of the Navy in 1981, TFR "Gepard" (built in 1954) - by order Navy Civil Code - in 1984, TFR "Los" (built in 1955), TFR - 55 (built in 1955), TFR - 50 (built in 1956), TFR - 54 (built in 1956), TFR - 10 (built in 1958) - by order of the Civil Code of the Navy - in 1987, Penguin TFR (built in 1954), TFR - 74 (built in 1956), TFR - 75 (built in 1956) - by order of the Civil Code of the Navy - in 1988, TFR "Lun" (built in 1954), TFR - 61 (built in 1956), TFR "Irkutsk Komsomolets" (built in 1956), TFR - 59 (1956) buildings), TFR - 4 (built in 1958) - by order of the Civil Code of the Navy - in 1989. The longest service life - 35 years as part of the Pacific Fleet was at the TFR "Lun".
