Soviet Submarine
Submarines of the Soviet Navy were developed by numbered "projects", which were sometimes but not always given names. During the Cold War, NATO nations referred to these classes by NATO reporting names, based on intelligence data, which did not always correspond with the projects. See: * List of NATO reporting names for ballistic missile submarines * List of NATO reporting names for guided missile submarines * List of NATO reporting names for hunter-killer and experimental submarines The NATO reporting names were based on the British (and later American) habit of naming submarines with a letter of the alphabet indicating the class, followed by a serial number of that class. The names are the radiotelephonic alphabet call sign of a letter of the alphabet. For security purposes, the "pennant numbers" of Soviet submarines were not sequential, any more than those of Soviet surface vessels were. Most Russian (and Soviet) submarines had no "personal" name, but were only known by a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shadowgraph Schuka Class III Series Submarine 01
Shadowgraph is an optical method that reveals non-uniformities in transparent media like air, water, or glass. It is related to, but simpler than, the schlieren and schlieren photography methods that perform a similar function. Shadowgraph is a type of flow visualisation. In principle, a difference in temperature, a different gas, or a shock wave in the transparent air cannot be seen by the human eye or cameras. However, all these disturbances refract light rays, so they can cast shadows. The plume of hot air rising from a fire, for example, can be seen by way of its shadow cast upon a nearby surface by the uniform sunlight. Sunlight shadowgraph Some aquatic predators detect their transparent prey by way of their shadows cast upon the ocean floor. It was Robert Hooke who first scientifically demonstrated the sunlight shadowgraph and Jean-Paul Marat who first used it to study fire. A modern account of shadowgraphy is given by Gary S. Settles.

Soviet S-class Submarine
The S-class or Srednyaya (, "medium") submarines were part of the Soviet Navy's underwater fleet during World War II. Unofficially nicknamed Stalinets (, "follower of Stalin"; not to be confused with the submarine L-class L-2 ''Stalinets'' of 1931), boats of this class were the most successful and achieved the most significant victories among all Soviet submarines. In all, they sank of merchant shipping and seven warships, which accounts for about one-third of all tonnage sunk by Soviet submarines during the war. Project history The history of the S class represents a turn in warship development. It was a result of international collaboration between Soviet and German engineers that resulted in two different (but nevertheless related) classes of submarines often pitted against each other in the war. In the early 1930s the Soviet government started a massive program of general rearmament, including naval expansion. Submarines were one key point of this program, but currently ...

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] |
