Midget submarines of the project 865 "Piranha"


		Midget submarines of the project 865 «Piranha»

Small submarine project 865 "Piranha" - a project of submarines the Navy of the USSR and the Russian Federation. Type was in the Navy armed with 1990 by 1999 of the year. There were built 2 Submarines of this project: MS-520 and MS-521. The further construction of such boats in the USSR has been suspended. As a result, a series of limited experimental MS-520 and MS-521 Head, donated to the Navy in December 1990 of the year.

In the second half of the 1970s the Soviet Navy Command issued Leningrad Special Maritime Bureau engineering "Malachite" specification for the design of the first draft of the Soviet midget submarine. TTZ determined, that this boat is designed for use in the maritime theater with an extensive shallow water area offshore, in depths ranging from 10 to 200 m. The submarine was supposed to solve the problem of counteraction to the enemy and to conduct exploration. To achieve these objectives by boat should place appropriate electronic weapons, Mining torpednoe oruzhie, as well as diving equipment to perform specific tasks on the depths to 60 m. TTZ on the displacement of the submarine could not exceed 80 tonnes.

The main designer of the project 865 He was appointed L. AT. Chernopyatov, which in 1984 He was succeeded by Yu. TO. Mineev. Since the earlier developments Ostekhbyuro by midget submarines were classified and well forgotten, again it took to begin the design "from scratch". In the course of designing the submarine project 865 a significant amount of development work has been carried out, modeling and field tests, experiments on individual designs, apparatuses and technological processes.

Bookmark experimental submarine was held at the Leningrad Admiralty Association in July 1984 of the year. Its dimensions are: length 28,2 m, width 4,7 m, average rainfall 3,9 m, Displacement above-water - 218 tonnes.

The design of the submarine 865 "Piranha"

Housing submarine project 865 It made of a titanium alloy and is designed for immersion depth 200 m. Complete underwater speed reached 6,7 knots, surfaced - 6 knots. Cruising range underwater economic progress (4 host) reached 260 miles, on the surface - 1000 miles.

In the control room operator console located, instrument rack and display facilities, as well as the bodies of the system and device management. Under the decking of the control room housed the battery hole. Closer to the nose of the operator console are the front hatch, periscope, Mine drawer radar complex. Central post nasal limited spherical bulkhead, which had a hatch in the airlock. At the bow window bulkhead located to monitor the work of divers, and a gateway for the transfer of objects from the camera CPU. There were also control devices locking system divers.

By electromechanical compartment central post separated flat aft bulkhead with gas-tight door. In the electromechanical compartment at amortized platform, cut off from the pressure hull, We stood on dampers diesel power generator 160 kW, dc propulsion motor in 60 kW, pumps, fans, compressor and other equipment. Due to the two-stage system of depreciation, coupled with noise absorbing coatings on the hull constructions submarine project 865 I had minimal acoustic field. Electromechanical compartment in the campaign only visited to check the status of technical equipment. Screw, Placed in a rotary annular nozzle, also served as the vertical rudder.

armament submarines 865 "Piranha"

Complex submarine weapons placed in the middle part of the superstructure and consisted of two freight containers for the transport of diving equipment (4 towing "Proton" type or 2 transporters such as "Siren-U") and 2 Device mine productions, which housed two mines such as PMT, or two gratings for 400-mm torpedo "Latouche"(special embodiment torpedo SET-72), used "samovyhodom" on the entire range of depths. Durable freight container filled with seawater, and represented approximately cylindrical design length 12 meters and a diameter of 62 cm. loading, unloading and mounting diving equipment provided for drawer. Drive and drawer controls are located inside the pressure hull.

mine setting device consisted of starting permeable grates with guide tracks rotor ejecting device, which kept pushing forward in the course of mine submarine. Also provides for the possibility of placing torpedoes instead mines. Electronic weaponry has been specially developed for this project. In the "Piranha" scripting compact radar system MRKP-60 "Radian-M", and the sonar system MGK-13C "Pripyat-S".

Crew

Submarine 'Piranha' project consisted of three officers: commander-navigator, Assistant electromechanical parts and electronic weapons Assistant. except them, It is taken on board the reconnaissance-sabotage group of six frogmen. Exit frogmen was carried out within the depths to 60 meters and on the ground. Being outside of the boat, combat swimmers / divers were able to use it supplied with electricity through the wires, as well as to replenish the gas mixture into the respiratory devices. During the operation of the submarine project for each boat it was formed by two replaceable crew. There is also a technical crew, designed to service both boats.

Service

20 August 1986 year pilot boat, received the MS-520 tactical Room, It was launched. Then for 2 years she passed factory and state tests, which ended only in December 1988 of the year. FROM 1989 , the MS-520 was in Liepaja as part of the 22nd brigade of submarines. The outputs of the submarine in the sea have been faced with difficulties, and combat training has been very difficult. In trials the submarine was hydronauts test 40 State Research Institute of the Ministry of Defense A. AND. Vatagin, which was subsequently awarded the title Hero of the Soviet Union.

Interesting Facts

One of the submarines of the project took part in the filming of the Russian film "Peculiarities of National Fishing".

During the investigation, a Ludwig Feinberg was arrested in the US, who recognized, that by request of one of the biggest drug dealers in the world, Pablo Escobar tried to acquire in Russia midget submarine boat project 865. Then the deal fell through.
