AK-257
The AK-257 is a Soviet 57mm naval gun, originally a land ZIF-31 L/70 57mm (Type 66/76) cannon. During the early 1950s, development began of naval versions of the 57x348mmSR 70 calibre weapon which had entered service with the Soviet army in 1950 as the S-60. This was to be a supplementary weapon for larger warships and as the main gun armament for minesweepers and auxiliaries. The twin gun version, ZIF-31, appears to have entered service with the Project 264 Minesweepers (T58 class) and the Project 310 (Don class) submarine support ships in 1958. In 1960, two other versions of the mounting appeared; a single gun ZIF-71 for the modernised Skoryy class destroyers and the quad ZIF-75 for the Krupny/Kanin class destroyers. The ZIF designation is an industrial one and it is possible that the naval designations were AK-157 (ZIF-71), AK-257 (ZIF-31) and AK-457 (ZIF-75). In smaller warships these mountings were sometimes associated with MR-103 and in larger ones with the Yakhond (Hawk Sc ... [...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 ...

Skoryy Class Destroyer
The ''Skory'' class were the first destroyers built for the Soviet Navy after World War II. Seventy (70) ships were built between 1949 and 1953. The Soviet designation was Project 30bis. Design The ships were derived from the Project 30 , but were slightly larger with better sea-keeping and significantly increased endurance. These ships were longitudinally framed and completely welded. The ships were built in 101 modular pre-fabricated sections which led to rapid building times. The machinery and main armament was essentially identical to those of the ''Ognevoy''-class destroyers but the boilers employed forced draught for increased power. Modernisation The ships were modernised in the 1950s with new anti-aircraft guns and anti-submarine mortars and updated sensors (new radar and sonar). One bank of torpedo tubes were removed and extra accommodation (deckhouses) added. Ships 70 ships were built for both the Soviet navy and for export, this is the largest production run for a ...

Destroyers
In naval terminology, a destroyer is a fast, manoeuvrable, long-endurance warship intended to escort larger vessels in a fleet, convoy or battle group and defend them against powerful short range attackers. They were originally developed in 1885 by Fernando Villaamil for the Spanish NavySmith, Charles Edgar: ''A short history of naval and marine engineering.'' Babcock & Wilcox, ltd. at the University Press, 1937, page 263 as a defense against torpedo boats, and by the time of the Russo-Japanese War in 1904, these "torpedo boat destroyers" (TBDs) were "large, swift, and powerfully armed torpedo boats designed to destroy other torpedo boats". Although the term "destroyer" had been used interchangeably with "TBD" and "torpedo boat destroyer" by navies since 1892, the term "torpedo boat destroyer" had been generally shortened to simply "destroyer" by nearly all navies by the First World War. Before World War II, destroyers were light vessels with little endurance for unattended ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grisha Class Corvette
The Grisha class, Soviet designation Project 1124 ''Al'batros'', are a series of anti-submarine corvettes built by the Soviet Union between 1970 and 1990 and later by Russia and Ukraine. These ships have a limited range and are largely used only in coastal waters. They have been equipped with a variety of ASW weapons and an SA-N-4 'Gecko' surface-to-air missile launcher. All were fitted with retractable fin stabilizers. The designation "corvette" for these ships was a conditional adaptation as the Soviet classification was a small anti-submarine ship (russian: Малый противолодочный корабль, Malyy protivolodochnyy korabl, Small anti-submarine ship) (MPK). In the Russian Navy, the Grishas are expected to be partially replaced by the ''Steregushchiy''-class corvette. Variants * Grisha I (1124.1) – 12 ships built between 1970 and 1974 and decommissioned by 1999 * The Grisha II class (1124P) were built for the KGB border guard and marked with ''P'' for ' ...

Naval Guns Of Russia
A navy, naval force, or maritime force is the branch of a nation's armed forces principally designated for naval and amphibious warfare; namely, lake-borne, riverine, littoral, or ocean-borne combat operations and related functions. It includes anything conducted by surface ships, amphibious ships, submarines, and seaborne aviation, as well as ancillary support, communications, training, and other fields. The strategic offensive role of a navy is projection of force into areas beyond a country's shores (for example, to protect sea-lanes, deter or confront piracy, ferry troops, or attack other navies, ports, or shore installations). The strategic defensive purpose of a navy is to frustrate seaborne projection-of-force by enemies. The strategic task of the navy also may incorporate nuclear deterrence by use of submarine-launched ballistic missiles. Naval operations can be broadly divided between riverine and littoral applications (brown-water navy), open-ocean applications ( ...
