USS Gwin (DM-33)
USS ''Gwin'' (DD-772/DM-33/MMD-33) was a destroyer minelayer in the United States Navy. She was named for William Gwin. ''Gwin'' was launched by the Bethlehem Shipbuilding, San Pedro, Los Angeles on 9 April 1944; sponsored by Mrs. Jesse W. Tarbill, second cousin and sponsor of the previous . The ship was commissioned on 30 September 1944 at Los Angeles. Service history World War II After shakedown along the California coast, ''Gwin'' sailed for the Pacific theatre as flagship of Mine Squadron 3, reaching Pearl Harbor 3 January 1945. A week later the squadron left for the fighting front. At Saipan, 20 January, ''Gwin'' and her sister minesweepers joined Battleship Division 7. For 7 days, 21 to 26 January, she participated in the preliminary bombardment of Iwo Jima, next to the last step in the island-hopping campaign across the Pacific.

William Gwin (naval Officer)
William Gwin (6 December 1832 – 3 January 1863) was an officer in the United States Navy who was killed in action during the American Civil War. One of the most promising officers in the nation, with extensive command and combat experience, Gwin had risen to the rank of lieutenant commander by the time of his death. Early life and career Born in Columbus, Indiana, Gwin was appointed a midshipman on 7 April 1847. Gwin subsequently served in the frigate on the Brazil Squadron until late in 1850.

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 ...

East China Sea
The East China Sea is an arm of the Western Pacific Ocean, located directly offshore from East China. It covers an area of roughly . The sea’s northern extension between mainland China and the Korean Peninsula is the Yellow Sea, separated by an imaginary line between the eastern tip of Qidong at the Yangtze River estuary and the southwestern tip of South Korea's Jeju Island. The East China Sea is bounded in the east and southeast by the middle portion of the first island chain off the eastern Eurasian continental mainland, including the Japanese island of Kyushu and the Ryukyu Islands, and in the south by the island of Taiwan. It connects with the Sea of Japan in the northeast through the Korea Strait, the South China Sea in the southwest via the Taiwan Strait, and the Philippine Sea in the southeast via gaps between the various Ryukyu Islands (e.g. Tokara Strait and Miyako Strait). Most of the East China Sea is shallow, with almost three-fourths of it being less than ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Fuji
, or Fugaku, located on the island of Honshū, is the highest mountain in Japan, with a summit elevation of . It is the second-highest volcano located on an island in Asia (after Mount Kerinci on the island of Sumatra), and seventh-highest peak of an island on Earth. Mount Fuji is an active stratovolcano that last erupted from 1707 to 1708. The mountain is located about southwest of Tokyo and is visible from there on clear days. Mount Fuji's exceptionally symmetrical cone, which is covered in snow for about five months of the year, is commonly used as a cultural icon of Japan and it is frequently depicted in art and photography, as well as visited by sightseers and climbers. Mount Fuji is one of Japan's along with Mount Tate and Mount Haku. It is a Special Place of Scenic Beauty and one of Japan's Historic Sites.

Naval Mine
A naval mine is a self-contained explosive device placed in water to damage or destroy surface ships or submarines. Unlike depth charges, mines are deposited and left to wait until they are triggered by the approach of, or contact with, any vessel or a particular vessel type, akin to anti-infantry vs. anti-vehicle mines. Naval mines can be used offensively, to hamper enemy shipping movements or lock vessels into a harbour; or defensively, to protect friendly vessels and create "safe" zones. Mines allow the minelaying force commander to concentrate warships or defensive assets in mine-free areas giving the adversary three choices: undertake an expensive 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 to declare mined areas, precise locations remain secret; and non-complying individ ...

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 lies approximately southwest of the capital, Tokyo. Cities on the bay include Odawara, Chigasaki, Fujisawa, Hiratsuka, Itō, and Kamakura. History The center of the Great Kantō earthquake in 1923 was deep beneath Izu Ōshima Island in Sagami Bay. It devastated Tokyo, the port city of Yokohama, and the surrounding prefectures of Chiba, Kanagawa, and 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 certain parts of the Shonan coast having suffered considerable damage, including the destruction of the Kōtoku-in temple hou ...

Tokyo Bay
is a bay located in the southern Kantō region of Japan, and spans the coasts of Tokyo, Kanagawa Prefecture, and Chiba Prefecture. Tokyo Bay is connected to the Pacific Ocean by the Uraga Channel. The Tokyo Bay region is both the most populous and largest industrialized area in Japan. Names In ancient times, Japanese knew Tokyo Bay as the . By the Azuchi–Momoyama period (1568–1600) the area had become known as after the city of Edo. The bay took its present name in modern times, after the Imperial court moved to Edo and renamed the city Tokyo in 1868. Geography Tokyo Bay juts prominently into the Kantō Plain. It is surrounded by the Bōsō Peninsula in Chiba Prefecture to the east and the Miura Peninsula in Kanagawa Prefecture to the west. The shore of Tokyo Bay consists of a diluvial plateau and is subject to rapid marine erosion. Sediments on the shore of the bay make for a smooth, continuous shoreline. Boundaries In a narrow sense, Tokyo Bay is the area north of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 GCI or AWACS-controlled to provide maximum early warning for defensive reaction. The first CAPs were characteristic of aircraft carrier operations, where CAPs were flown to ...

Mitsubishi G4M
The Mitsubishi G4M was a twin-engine, land-based medium bomber formerly manufactured by the Mitsubishi Aircraft Company, a part of Mitsubishi Heavy Industries, and operated by 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 penchant for igniting 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 suffering heavy losses; Allied fighter pilots nicknamed the G4M "The Flying L ...

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, and more than 7,000 naval personnel were killed by ''kamikaze'' attacks. ''Kamikaze'' aircraft were essentially pilot-guided explosive missiles, 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 and or other explosives. About 19% of ''kamikaze'' attacks were successful. The Japanese considered the goal of damaging or sinking large numbers of Allied ships to be a just reason for suicide attacks; ''kamikaze'' was more accurate than conventional attacks and often cau ...

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. 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 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. Airborne radar pickets are generally referred to as airborne early warning (AEW). In a sense radars intended to track ballistic missiles can be thought of as radar pickets, but because such systems are also used ...
