The name ''vetehinen'' means " merman". Combat operations Winter War The Finnish Navy was informed that the 8,800 ton Soviet icebreaker would be arriving in the Baltic Sea from the Atlantic. ''Vetehinen'' was sortied to intercept the icebreaker off the port of Liepāja on 4 December. However, the submarine ran aground before reaching open sea and had to be pulled loose by tugs before it was able to start its voyage. ''Vetehinen'' arrived at the site on 6 December and started patrolling off the buoy on the port entrance. On 7 December the submarine sighted ''Yermak'' but was unable to reach it. While on station, ''Vetehinen'' encountered a couple of unknown submarines which were suspected to be of German origin. On 8 December ''Vetehinen'' began the voyage home and was attacke ...

Crichton-Vulcan
Crichton-Vulcan is an abandoned shipyard in Turku, Finland, that once formed the cornerstone of the Finnish shipbuilding industry. The shipyard is best known for the World War II coastal defence ships and submarines it produced. Shipbuilding at the yard gradually ended after 1976, after a new shipyard had been built in the suburb Perno. The old yard was taken over by Turku Repair Yard and used for ship repair until 2004, when they too moved to the nearby city of Naantali. The shipyard by the Aura River in Turku then lay abandoned some time and was the target of vandalism. However, the site is currently being turned into an upper-class residential area. Demolition of the old buildings began in June 2011. History The first shipyard in Turku was established in 1732 on the eastern bank of the Aura River. The first foundry and metal workshop was established in 1842. After the Crimean War the workshop was acquired by Scotsman William Crichton. Crichton built a new shipyard ...

Sea Of Åland
The Åland Sea (or the Sea of Åland; sv, Ålands hav, fi, Ahvenanmeri) is a waterway in the southern Gulf of Bothnia, between Åland and Sweden. It connects the Bothnian Sea with the Baltic Sea proper. The western part of the basin is in Swedish territorial waters while the eastern part is in Finnish territorial waters. The Åland Sea has two sub-basins. The main basin is the Åland Sea proper, also called the northern Åland Sea basin. In the south, there is the smaller Lågskär Deep, also called the Lågskär Basin or the southern Åland Sea basin. The narrowest part on the northern edge of the basin is named the Southern Quark or South Kvarken ( sv, Södra Kvarken, fi, Ahvenanrauma). The trench running on the bottom of the Sea of Åland contains the second-deepest spot of the Baltic Sea, at a depth of 301 meters, which is second only to Landsort Deep. The mean depth of Åland Sea is 75 m, area 5,477 km2 and its volume is 411 km³. The Archipelago Sea and the Ål ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Depth Charge
A depth charge is an anti-submarine warfare (ASW) weapon. It is intended to destroy a submarine by being dropped into the water nearby and detonating, subjecting the target to a powerful and destructive Shock factor, hydraulic shock. Most depth charges use explosive, high explosive charges and a fuze set to detonate the charge, typically at a specific depth. Depth charges can be dropped by ships, patrol aircraft, and helicopters. Depth charges were developed during World War I, and were one of the first viable methods of attacking a submarine underwater. They were widely used in World War I and World War II, and remained part of the anti-submarine arsenals of many navies during the Cold War, during which they were supplemented, and later largely replaced, by anti-submarine homing torpedoes. A depth charge fitted with a nuclear warhead is also known as a "nuclear depth bomb". These were designed to be dropped from a patrol plane or deployed by an anti-submarine missile from a s ...

Battle Of Hanko (1941)
The Battle of Hanko (also known as the Hanko front or the siege of Hanko) was a lengthy series of small battles fought on Hanko Peninsula during the Continuation War between Finland and the Soviet Union in the second half of 1941. As both sides were eager to avoid a major, costly ground battle, fighting took the form of trench warfare, with artillery exchanges, sniping, patrol clashes, and small amphibious operations performed in the surrounding archipelago. A volunteer Swedish battalion served with Finnish forces in the siege. The last Soviet troops left the peninsula in December 1941. Background As part of the 1940 Moscow Peace Treaty which formally ended the Soviet-Finnish Winter War, Hanko was leased to the Soviet Union as a Soviet naval base. The civilian population was forced to evacuate before Soviet forces arrived. The leased area included several surrounding islands, several coastal artillery sites (among them the important fort of Russarö), important harbor f ...

MO-class Small Guard Ship
The MO (russian: Малый Охотник, ''Malyj Okhotnik''; en, Small Hunter, nickname ''Moshka'' (''Midge'') is a class of small ships produced before and during World War II for the Soviet Navy. Their primary function originally was anti-submarine warfare. During the war they carried out many additional roles from supporting landing operations to escorting convoys. Over 350 ships were built.Military Ships of Russia , p. 80 Background In early 1930s, the main focus of Soviet shipbuilding was building small patrol ships and boats with various duties. Among them, a large part consisted of submarine hunter boats. The MO class was the first Soviet built submarine hunter ship class, with the abbreviation meaning "Small Hunter". Unlike torpedo boats, MO boats had no torpedo weapons, but instead had depth charge launchers. Design history MO-1, MO-2 and MO-3 types The first ship of the class was a border patrol boat PK-139, which was given the class designation of MO-1 in 1935. ...

Minesweeper
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 Grappling hook, 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 ...
