Project 615 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 B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Submarine Classes
A submarine (or sub) is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. The term is also sometimes used historically or colloquially to refer to remotely operated vehicles and Autonomous underwater vehicle, robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub. Submarines are referred to as ''boats'' rather than ''ships'' irrespective of their size. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and they were adopted by several navies. They were first widely used during World War I (1914–1918), and are now used in many navy, navies, large and small. Military uses include attacking enemy surface ships (merchant and military) or other submarines, and for aircraft carrier protection, Blockade runner, blockade running, Ballistic missile submarine, nuclear deterrence, reconnaissance, conventio ...

M 261
M, or m, is the thirteenth letter in the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''em'' (pronounced ), plural ''ems''. History The letter M is derived from the Phoenician Mem, via the Greek Mu (Μ, μ). Semitic Mem is most likely derived from a " Proto-Sinaitic" ( Bronze Age) adoption of the "water" ideogram in Egyptian writing. The Egyptian sign had the acrophonic value , from the Egyptian word for "water", ''nt''; the adoption as the Semitic letter for was presumably also on acrophonic grounds, from the Semitic word for "water", '' *mā(y)-''. Use in writing systems The letter represents the bilabial nasal consonant sound in the orthography of Latin as well as in that of many modern languages, and also in the International Phonetic Alphabet. In English, the Oxford English Dictionary (first edition) says that is sometimes a vowel, in words like ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
