Poti class Corvettes (1960)

Project 204 (NATO Poti class were sixty six anti-submarine warfare (ASW) corvettes built for the Soviet Navy and the first Soviet warships ever powered by gas turbines, with tunneled propellers for a very shallow draught, elabling them to perform coastal ASW patrols. They were armed with a twin 57 mm gun mounting for self-defence and a combination of RBU rocket launchers and heavy acoustic torpedoes to hun down US submarines. Construction in three yards ceased in 1968, but they were also exported to Romania and Bulgaria as only foreign users of the type. #coldwar #project204 #poticlass #aswcorvettes #antisubmarienwarfare #corvette #sovietnavy #sovietskyflot

Development

Designated “Maly Protivo Lodochny Korabl” (Small Anti-submarine Ship) the ship of Project 204 departed from WW2 light sub-chasers types used by the Soviet Navy, not the mass-produced Kronshtadt and SO1 classes. The advantage of that up-scaling was of course to to mount larger guns for a more robust defense, longer range and heavier armament, following the evolution of potentiual enemy submarines, notably in NATO, such as the first SSNs derived from USS Nautilus. They were also the first large Soviet warships with gas turbines and thus became the fastest ASW warships ever constructed at the time in order to chase these new SSNs that promised potential speeds in excess of 30 knots.

Project 204 were essentaially a modification and further development of Project 201 boats. Development start was assigned in 1956 to Zelenodolsk Design Bureau. A.V. Kunakhovich became chief designer, captain 2nd rank N.D. Kondratenko appointed chief observer. Standard displacement was increased to 440 tons, and the armament increased significantly. After trials of the ship down the line, its designers were awarded the Lenin Prize.
What they did for the powerplant indeed was revolutionary. They had the propellers installed in stern wells, with nozzles. They were were rotated by M-504 diesel engines, which in turn rotated at high speed behind D-2K gas turbine compressors, which pumped air into the propeller wells to create additional thrust. This unique arrangement doubled the speed compared to previous Project 201 vessels and answered one of the main specifications, chase down faster SSNs. Such installation was also tested previously on Project 35 patrol ships, but with classic external props, there was no increase in speed, and it revealed not suitable in many other respects. But the success of the new arrangement, done thanks to the collaboration of specialists of cavitation and fluid mechanism helped to shape this unique arrangement.

Initially, B.K. Ilyinsky was considered its author, but after the collapse of the USSR, newly released information revealed actually it was K.A. Putilov in 1946. After a meeting with Iosif Stalin on improving sub-hunters performances in coastal waters, he worked with scientists on a new power plant, but without funding it went nowhere. Wuth the revelation of USS Nautilis however, his concept was resurrected. Help was provided also by an unlikely ally, the NKVD, which helped find at the Department of Physics of the Moscow Aviation Institute (K.A. Putilov) a group led by A.V. Volkov, working on the adaptation of jet engines for ships.

In ten days, a laboratory was organized, headed by K.A. Putilov, but results did not came at first. Only the 1953-55 first full-scale tests carried out made it possible to define a workable solution and power plant. In 1951, the Central Research Institute Krylov was at the head of the Ministry of Shipbuilding for scientific support. It managed at the final stage to appoint its representative B.K. Ilyinsky, replacing K.A. Putilov’s after he passed out, and brought research work to its conclusion.

Also in the specifications, the design saw the Anti-submarine armament precised. Due to the lack of free space, despite the size, and the use of new acoustic, homing torpedoes, it was now possible to have simple, fixed single tubes. They were to fire 400-mm SET-40 anti-submarine torpedoes. This was complemented by also a relatively new (but soon stadard) RBU-6000 launchers. As thyey were still not ready, the previous RBU-2500 were installed on the first two hulls as a provisional measure. The artillery consisted of a twin automatic 57-mm AK-725 turret, but also the configuration placing both the rocket launchers forward on superfiring position for the best arc of fire, had the turret used for self-defence relocated amidships. Again, the first two ships differed by having, also provisionally, an open ZIF-31 mount. The turret was controlled by the new “Bars” control radar. The way it was placed was far from ideal, but there was really no choice as the stern space wasoccupied by humongus air intakes necessary for the propeller tunnels and essentual to the main power plant. For situational awareness, the Rubka radar was installed, while for unerwater surveillance, the Hercules-2M hull sonar was chosen, complemented by a Bizan-4B complex, the first production dipping sonar in Soviet inventory.

Construction

These ships were built in Khabarovsk, Zelenodolsk and Kerch, these 66 units (project 204) were specialized in coastal ASW control and cheaper than the class Petya or Mirka frigates. They had new M2 gas turbines, giving them 38 knots, the best speed ever recorded by a Soviet ship of this type. The vents of these turbines exceeded the stern structure, which also housed two ASM grenades bins. The first units (there is no Poti I or Poti II) were equipped with the open version of the twin 57 mm AA, and two ASW rocket launchers type RBU 2500. They also had 4 ASW torpedo tubes (fixed) 406 mm, replaced on the three units delivered in 1937 to Romania by standard heavy torpedo 533 mm TTs. Three other units were delivered to Bulgaria in 1973.

Three Yard built 66 ships, 31 at Gorky (Zelenodolsk), 24 at Zaliv (Kerch) and 11 at Khabarovsk. Six were later transferred to the Bulgarian Navy and became “Hrabri”, “Strogi”, “Letyaschi”, “Bezstrashni”, “Bditelni” and “Naporisti”. Three ships went as export (paid for) by the Romanian Navy and known as export project 204-E, with a simpler layout. They were the only variant known for these mass-built vessels. It turned out that these ships arrived in the fleet during a period of rapid growth in combat capabilities both of submarines and aviation and became obsolete at least in armament and sensors. To such extent the Commander-in-Chief ordered the development of a new ship with increased air defense capabilities and a better sonar system to become the the workhorse of the fleet.
The Poti class ended in all four fleets of the Soviet Navy: Black Sea Fleet had 17 ships, the Pacific fleet obtained 11, the Baltic obtained 22 and Northern fleet 11 ships. In the mid-1980s until the collapse of the Soviet union they were all of decommissioned, or converted as experimental vessels, or training.
Accurate information on the fate of these ships is scarce, but it appears that all units (except those transferred) were in service as 1980 started. In 1990 les than 50% were still “active” whatever their status and conditions. The Black Sea Fleet’s website still showed 17 Poti class active (including one until 1975), 12 by 1990, two 1998, but as experimental vessels. None survived to this day.

These were the first large Soviet gas turbine warships, featuring this revolutionary M-2 engine and achieving 38kts, making them the fastest Soviet ASW ships ever built thanks to their propellers in thrust tubes, exhaust through ports above them in the transom, as well as air compressors for added thrust.
Modernizations started in 1970, with MPK-150 receiving for trials the new VGS-2 Oka-M sonar, while MPK-74 and MPK-83 tested the MG-7 Braslet sonar, MPK-74 received two UB-16-57UMP decoy launchers and two PK-16 decoy launchers.

Design of the class

Seen from above, model.

Hull and general design

Corvettes of Poti class measured 59.4 metres (194 ft 11 in) long with a beam of 7.9 m (25 ft 11 in) and a draught of 2.0 m (6 ft 7 in). They had a standard displacement of 508 tonnes (500 long tons) and 589 t (580 long tons) fully loaded. The design overall looked very peculiar. The hull design in particular. Seen from the side, it was flush-deck, with a raised aft section, which underwater profile was shaped in a very peculiar way due to the absence of propeller shafts or struts. This made them able almost to beach anywhere and still be able to stay undamaged. This made perfect shallow waters operations, coastal and on the continental shelf, the Baltic and black sea. Their complement was 80 between officers and ratings.

The hull entry lines forward were very fine, translated on deck, despite the flare, to an arrowhead like profile, with a larger aft section ending on an equally large transom stern. The hull was shaped almost like a trimaran aft, with three small rudders. The profile was peculiar, with the two RBU launchers taking most of the fore section, followed by a small, compact and open bridge structure, which vision was obstructed by the “B” RBU launcher. It was followed by a the lattice mainmast supporting radars and aerials. Then came a small “island” structure supporting the artillery control radar, and aft communication antennae. Both the turret was installed there, amidships, as well as the four torpedo tubes, two pairs either beam, oriented forward to an angle of c20° from the axis. The aft raised section devoted to the powerplant was marked by the four massive air intakes, turned backwards, feeding both the engine and tunnel, making these small ships quite unique in appareance and unlike nothing else.

Powerplant

The ships were powered by a two shaft system, combined diesel and gas (CODAG) propulsion. In order, there were two M503A diesel engines rated for 6,000 kW (8,000 bhp) as primary power source. They could be used alone to power electrical systems aboard when the ship was in port. They turned through a gearbox and demultiplicated gears to augment rpm, the M-2 gas turbines, which provided the 22,000 kilowatts (30,000 shp) -properly amazing for their size- which in turn turned the two propellers, having a short shaft. In ways it was the same as for the Mirka class but managed differently.

They were mounted in thrust tubes extended all the way to the transom stern. The gas turbines exhausted through ports in the transom instead of classic funnels. They also created a powerful air draft and powered air compressors exhausting into the thrust tubes. This extra thrust was the “secret weapon” in this propulsion design. This gave them the unprecedented speed of 38 knots (70 km/h; 44 mph), until then reserved to Fast attack crafts. The range still thanks to diesel was 4,500 nautical miles (8,300 km; 5,200 mi) at 10 knots (19 km/h; 12 mph) which was perfectly viable in their restricted area of operation. This fell to 520 nautical miles (960 km; 600 mi) at 37 knots (69 km/h; 43 mph) when chasing a submarine. USS Nautilus at the time was “only” capable of 23 knots at best (43 km/h; 26 mph). There was room for manoeuver here. On the next gen Los Angeles class, it was closer to 33 kts (classified).

SET-40 Torpedoes

Some ships had from two to four 406 mm (16 in) single torpedo tubes launching the Type 40 ASW torpedoes. They had active/passive homing up to 8 nmi (15 km; 9.2 mi) and ran at 40 knots (74 km/h; 46 mph) to target, delivering a 100–150 kg (220–330 lb) warhead on contact. This Lightweight ASW torpedo entered service in 1962 after a 1959-1961 development by NII-400 Gidropribor and produced by Dvigatel. The name meant “Spetsialnaya Elektricheskaya Torpeda 40” for “special electric torpedo 40”, MGT-2, Izdeliye 241, NATO Type 40. It had the same parameters as the 400mm MGT-1 lightweight torpedo, divided into four compartments with in order the sensor, warhead, battery and engine compartment. Propulions is the scaled down SET-53M torpedo system, electric, single propeller with silver-zinc batteries seawater activated.
It was the first design with both active and passing homing, 1st gen acoustic sensor with a 600 to 800 m range and Sapfir sensor partly based on recuperated US technology.
8 km range at 29 knots and a 80 kg with acoustic proximity fuse plus backup contact fuse. They were installed on the Poti class in four single angled deck mounted tubes with powder charges and datalink with a fire control system plus backup manual input.

post-World War II, Bulgaria entered the Soviet sphere of influence and in the 1950s, the whole Bulgarian military, including the navy, had been re-organised along Soviet lines. Soviet armaments were then sold, including for the Navy. In 1955, Bulgaria acquired Kronstahdt-class submarine chasers to bolster the Black sea ASW forces. Bulgaria however later required replacements as they were obsolete in the 1970s and obtained six Poti-class, transferred from 1975 to 1990. They were the former MPK-59, MPK-77 and MPK-109 for those known with certainty. By 2008 they were all discarded.
These were in order:
-#44 Khrabri in 1986, Decommissioned 2005, sold.
-#45 Strogi 1990[, Decommissioned 1993, sold for BU Turkey 1997.
-#46 Bezstrashni in 1990. She had her Gas turbines removed in 1994, used a training hulk and decommissioned in 2005, sold for BU.
-#41 Letjashhi was the first transferred on December 1975. She was Decommissioned in 2005, sold.
-#42 Bditelni also transferred December 1975, Decommissioned 2005, sold
-#43 Naporisti was for former MPK-148, transferred December 1975, Decommissioned 1993, sank during towing to Turkey for BU in 1997.

Romania also was under the Soviet Union’s sphere of influence when joining the Warsaw Pact and from 1964 the local industry massively took on national procurement, and started to diverge from Soviet direction with a rift between countries widening in 1968 after the invasion of Czechoslovakia. Three Poti-class were nevertheless to the Romanian Navy in 1970 to carry out ASW tasks on the Black sea from Constanta. These were early vessels downgraded with the RBU-2500 ASW rocket launchers and 533 mm (21 in) with the Type 53 (SET-53) torpedoes. They came from Zelenodolsk yard, transferred upon completion, with MPK-106 and MPK-125 among them:
#31 Contraamiral Nicolae Cristescu, transferred 5 December 1968, Decommissioned after 1992
#32 Contraamiral Nicolae Negru, transferred 1 April 1969, Decommissioned after 1992
#33 Contraamiral Irimescu, transferred 20 October 1969, Decommissioned after 1992
