Quebec Class Submarine
The Quebec-class submarine was the NATO reporting name of the Soviet Project 615 submarine class, a small coastal submarine of the late 1950s. Background Prior to World War II, work on closed-cycle diesel engines was carried out by S.A. Basilevskiy, who developed a powerplant codenamed REDO. The exhaust gases from the diesel engine were compressed and the carbon dioxide extracted and dumped overboard, before the purified gases were mixed with stored oxygen and fed back into the engine. A prototype of this powerplant was installed in the experimental submarine ''M-401'', laid down at Gorky on 28 November 1939 and launched on 31 May 1941. ''M-401'' made 74 cruises in the Caspian Sea including 68 dives and of submerged running on its closed-cycle plant. Further work was temporarily suspended due to the war but was resumed after hostilities ended, at Leningrad. The data obtained from trials of ''M-401'' formed a basis for the design of the Project 615 ''Quebec''-class. Descrip ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soviet M-class Submarine
The M-class submarines, also ''Malyutka'' class (russian: Малютка; ''baby'' or ''little one''), were a class of small, single-, or 1½-hulled submarines built in the Soviet Union and used during World War II. The submarines were built in sections so they could easily be transported by rail. The production was centered in the Gorky Shipyard on the Volga River, after which the sections were transported by railway to Leningrad for assembly and fitting out. This was the first use of welding on Soviet submarines. History 1930s to 1940s Submarines of this class were in four series: VI, VI-bis, XII, XV. The number of VI and VI-bis series boats were almost equal. Series XII was a re-developed project with equivalent tactical characteristics. The first series were powered by one diesel engine and one electric motor. Series XV had developed separately with improved characteristics, including the main ballast in light hull and two shafts. These vessels were mainly used by the Blac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
