MT Class Minesweeper
The MT class were a group of coastal minesweepers built for the Soviet Navy in the 1943-1945. The Soviet designation was Project 253L. Design The specifications for the ''Project 253'' were issued in April 1942 by admiral Lev Galler. Initial design iteration made by TsKB-32 was unsatisfactory and was transferred in 1943 to TsKB-51 for improvements, resulting in ''Project 253L'' (named after chief designer N. G. Loshchinskii). The minesweepers were badly needed in the heavily mined Baltic Sea, therefore pre-production series comprising 32 vessels were ordered 12 April 1943, followed by full-capacity production on two shipyards starting from 12 June 1943. The minesweeper was extremely successful, resulting in 4 shipyards assigned to its production starting from 31 October 1943.Mikhail Monakov, Jurgen Rohwer, "Stalin's Ocean-going Fleet: Soviet Naval Strategy and Shipbuilding Programs 1935-1953", p.155 Two main versions were produced: *''MT-1'' (June 1943) - full displacement 126.6 ...

45 Mm Anti-aircraft Gun (21-K)
The 45 mm anti-aircraft gun (21-K) was a Soviet design adapted from the 45 mm anti-tank gun M1932 (19-K). This was a copy of a German weapon designed by Rheinmetall that was sold to the Soviets before Hitler came to power in 1933 that had been enlarged to to reuse a large stock of old 47mm ammunition. It was used by the Soviet Navy to equip almost all of their ships from 1934 as its primary light anti-aircraft gun until replaced by the fully automatic 37 mm ''70-K'' gun from 1942 to 1943. It was used in World War II and during the Cold War as the Soviets exported their World War II-era ships to their friends and allies. However it was not very effective as its slow rate of fire and lack of a time fuze required a direct hit to damage targets. Design The 46- caliber''21-K'' was a minimal adaptation of the 53-K anti-tank gun that was created by taking the latter's barrel and mounting it on a simple pedestal mount. Its semi-automatic breech automatically ejected the ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minesweeper (ship)
A minesweeper is a small warship designed to remove or detonate naval mines. Using various mechanisms intended to counter the threat posed by naval mines, minesweepers keep waterways clear for safe shipping. History The earliest known usage of the naval mine dates to the Ming dynasty.Needham, Volume 5, Part 7, 203–205. Dedicated minesweepers, however, only appeared many centuries later during the Crimean War, where they were deployed by the British. The Crimean War minesweepers were rowboats trailing grapnels to snag mines. Minesweeping technology picked up in the Russo-Japanese War, using aging torpedo boats as minesweepers. In Britain, naval leaders recognized before the outbreak of World War I that the development of sea mines was a threat to the nation's shipping and began efforts to counter the threat. Sir Arthur Wilson noted the real threat of the time was blockade aided by mines and not invasion. The function of the fishing fleet's trawlers with their trawl gear was ...

Lev Galler
Lev Mikhailovich Galler (Born Leo Julius Alexander Philipp von Haller; russian: Лев Михайлович Галлер; – 12 July 1950) was a Soviet military leader and admiral of Baltic German origin. Galler was born into a Baltic German family of a military engineer Philipp Michael Hugo von Haller (Galler) and joined the Baltic Fleet on completing the Naval school in 1905. During World War I he was squadron gunnery officer of the Battleship Division, executive officer of the ''Slava'' and commanded the destroyer ''Turkmenets Stavropolski''. After the October Revolution he joined the Bolsheviks and participated in the Ice Cruise of the Baltic Fleet. Subsequently, he commanded the destroyer ''Mecheslav'', the battleship ''Andrei Pervozvanny'' and was subsequently chief of staff of the Baltic Fleet during the British Campaign in the Baltic 1918–1919. After the Civil War, Galler was commander of the Baltic Fleet's battleship division and commanded the Baltic Fleet from 193 ...

German Submarine U-481
German submarine ''U-481'' was a Type VIIC U-boat of Nazi Germany's '' Kriegsmarine'' during World War II. The submarine was laid down on 6 February 1943 at the Deutsche Werke yard in Kiel, launched on 25 September 1943, and commissioned on 10 November 1943 under the command of ''Oberleutnant zur See'' Ewald Pick. Design German Type VIIC submarines were preceded by the shorter Type VIIB submarines. ''U-481'' had a displacement of when at the surface and while submerged. She had a total length of , a pressure hull length of , a beam of , a height of , and a draught of . The submarine was powered by two Germaniawerft F46 four-stroke, six-cylinder supercharged diesel engines producing a total of for use while surfaced, two Siemens-Schuckert GU 343/38–8 double-acting electric motors producing a total of for use while submerged. She had two shafts and two propellers. The boat was capable of operating at depths of up to . The submarine had a maximum surface speed of a ...

Cold War Minesweepers Of The Soviet Union
Cold is the presence of low temperature, especially in the atmosphere. In common usage, cold is often a subjective perception. A lower bound to temperature is absolute zero, defined as 0.00K on the Kelvin scale, an absolute thermodynamic temperature scale. This corresponds to on the Celsius scale, on the Fahrenheit scale, and on the Rankine scale. Since temperature relates to the thermal energy held by an object or a sample of matter, which is the kinetic energy of the random motion of the particle constituents of matter, an object will have less thermal energy when it is colder and more when it is hotter. If it were possible to cool a system to absolute zero, all motion of the particles in a sample of matter would cease and they would be at complete rest in the classical sense. The object could be described as having zero thermal energy. Microscopically in the description of quantum mechanics, however, matter still has zero-point energy even at absolute zero, be ...
