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, when 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, 3rd Baronet, Sir Arthur Wilson noted the real threat of the time was a blockade aided by mines and not an invasion. The function of the ...

Naval Mine
A naval mine is a self-contained explosive weapon placed in water to damage or destroy surface ships or submarines. Similar to anti-personnel mine, anti-personnel and other land mines, and unlike purpose launched naval depth charges, they are deposited and left to wait until, depending on their fuzing, they are triggered by the approach of or contact with any vessel. Naval mines can be used offensively, to hamper enemy shipping movements or lock vessels into a harbour; or defensively, to create "safe" zones protecting friendly sea lanes, harbours, and naval assets. Mines allow the minelaying force commander to concentrate warships or defensive assets in mine-free areas giving the adversary three choices: undertake a resource-intensive and time-consuming minesweeping effort, accept the casualties of challenging the minefield, or use the unmined waters where the greatest concentration of enemy firepower will be encountered. Although international law requires signatory nations ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sagami Bay
lies south of Kanagawa Prefecture in Honshu, central Japan, contained within the scope of the Miura Peninsula, in Kanagawa, to the east, the Izu Peninsula, in Shizuoka Prefecture, to the west, and the Shōnan coastline to the north, while the island of Izu Ōshima marks the southern extent of the bay.

It devastated Tokyo, the port city of Yokohama, and the surrounding prefectures of Chiba Prefecture, Chiba, Kanagawa, and Shizuoka Prefecture, Shizuoka, and caused widespread damage throughout the Kantō region. The shallow nature of the seabed on the north of the bay, and the funnelling effect of tsunami and typhoon wave energy, contributed to cer ...

Combat Air Patrol
Combat air patrol (CAP) is a type of flying mission for fighter aircraft. A combat air patrol is an aircraft patrol provided over an objective area, over the force protected, over the critical area of a combat zone, or over an air defense area, for the purpose of intercepting and destroying hostile aircraft before they reach their target. Combat air patrols apply to both overland and overwater operations, protecting other aircraft, fixed and mobile sites on land, or ships at sea. Known by the acronym CAP, it typically entails fighters flying a tactical pattern around or screening a defended target, while looking for incoming attackers. Effective CAP patterns may include aircraft positioned at both high and low altitudes, in order to shorten response times when an attack is detected. Modern CAPs are either Ground-controlled interception, GCI or Airborne Early Warning and Control, AWACS-controlled to provide maximum early warning for defensive reaction. The first CAPs were charac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mitsubishi G4M
The Mitsubishi G4M is a twin-engine, land-based medium bomber formerly manufactured by the Mitsubishi Aircraft Company, a part of Mitsubishi Heavy Industries, and operated by the Air Service (IJNAS) of the Imperial Japanese Navy from 1940 to 1945. Its official designation is and was commonly referred to by Japanese Navy pilots as due to the cylindrical shape of its fuselage and its tendency to ignite after a hit. The Allied reporting name was "Betty". Designed to a strict specification to succeed the Mitsubishi G3M already in service, the G4M boasted very good performance and excellent range and was considered the best land-based naval bomber at the time. This was achieved by its structural lightness and an almost total lack of protection for the crew, with no armor plating or self-sealing fuel tanks. The G4M was officially adopted on 2 April 1941, but the aforementioned problems would prove to be a severe drawback, often resulting in heavy losses; Allied fighter pilots ...

Kamikaze
, officially , were a part of the Japanese Special Attack Units of military aviators who flew suicide attacks for the Empire of Japan against Allied naval vessels in the closing stages of the Pacific campaign of World War II, intending to destroy warships more effectively than with conventional air attacks. About 3,800 ''kamikaze'' pilots died during the war in attacks that killed more than 7,000 Allied naval personnel, sank several dozen warships, and damaged scores more. The term is used generically in modern warfare for an attacking vehicle, often unmanned, which is itself destroyed when attacking a target; for example, a kamikaze drone. ''Kamikaze'' aircraft were pilot-guided explosive missiles, either purpose-built or converted from conventional aircraft. Pilots would attempt to crash their aircraft into enemy ships in what was called a "body attack" (''tai-atari'') in aircraft loaded with bombs, torpedoes or other explosives. About 19 percent of ''kamikaze'' attacks ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radar Picket
A radar picket is a radar-equipped station, ship, submarine, aircraft, or vehicle used to increase the radar detection range around a nation or military (including naval) force to protect it from surprise attack, typically air attack, or from criminal activities such as smuggling. The term ' picket' is an old military term for a sentry placed forward of a defensive line, in order to provide an advanced warning. By definition a radar picket must be some distance removed from the anticipated targets to be capable of providing ''early warning''. Often several detached radar units would be placed in a ''ring'' to encircle a target to provide increased cover in all directions; another approach is to position units to form a ''barrier line''. Radar picket units may also be equipped to direct friendly aircraft to intercept any possible enemy. In British terminology the radar picket function is called aircraft direction. A ship performing this function is termed a fighter direction ship ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
