Action Of 9 February 1945
During the action of 9 February 1945, , a V-class submarine of the Royal Navy, which was patrolling the waters around Fedje Island, off the Norwegian coast in the North Sea, attacked and sank the German U-boat . The sinking is the only incident where one submarine sank another in combat while both were at periscope depth. Background U-864 60°46′10″N 4°37′15″E ''U-864'' was a Type IX U-boat ( Ralf-Reimar Wolfram) on a clandestine mission, Operation Caesar, to the Empire of Japan. On 6 February 1945, ''U-864'' passed through the Fedje area off the Norwegian coast without being detected but an engine kept misfiring. In 1986, G. P. Jones wrote that sound probably came from "noisy machinery". In 2013, Preisler and Sewell wrote that an air compressor may have been wrongly installed or had worn out causing the engine to misfire with "loud, fitful vibrations". There were many Allied (primarily British) ships, submarines and aircraft in the area on anti-submarine patrol. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of The Atlantic
The Battle of the Atlantic, the longest continuous military campaign in World War II, ran from 1939 to the defeat of Nazi Germany in 1945, covering a major part of the naval history of World War II. At its core was the Allied naval blockade of Germany, announced the day after the declaration of war, and Germany's subsequent counter-blockade. The campaign peaked from mid-1940 through to the end of 1943. The Battle of the Atlantic pitted U-boats and other warships of the German '' Kriegsmarine'' (Navy) and aircraft of the ''Luftwaffe'' (Air Force) against the Royal Navy, Royal Canadian Navy, United States Navy, and Allied merchant shipping. Convoys, coming mainly from North America and predominantly going to the United Kingdom and the Soviet Union, were protected for the most part by the British and Canadian navies and air forces. These forces were aided by ships and aircraft of the United States beginning September 13, 1941. Carney, Robert B., Admiral, USN. "Comment and Discu ...

Submarine Warfare In World War II
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 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 navies, large and small. Military uses include attacking enemy surface ships (merchant and military) or other submarines, and for aircraft carrier protection, blockade running, nuclear deterrence, reconnaissance, conventional land attack (for example, using a cruise missile), and covert insertion of spe ...

Naval Battles Of World War II Involving Germany
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 applicati ...
