ARV Carite (S-11)
USS ''Tilefish'' (SS-307), a ''Balao''-class submarine, was the only ship of the United States Navy to be named for the tilefish, a large, yellow-spotted deepwater food fish. Her keel was laid down on March 10, 1943 at Vallejo, California, by the Mare Island Navy Yard. She was launched on October 25, 1943 sponsored by Mrs. Wilson D. Leggett, and commissioned on December 28, 1943. First and second war patrols During February and March 1944, ''Tilefish'' underwent trials and shakedown off the California coast before getting underway for Hawaii. On April 3, the submarine departed Pearl Harbor for her first war patrol, setting course for the Japanese home islands. While patrolling in the "Hit Parade" area east of Honshū, ''Tilefish'' sighted many enemy aircraft but found few targets for her torpedoes. Early in the patrol, she was hampered by the failure of her fathometer; and, throughout the mission, she was plagued by periscope fogging and overcast weather which ruled out cele ...

Mare Island Naval Shipyard
The Mare Island Naval Shipyard (MINSY) was the first United States Navy base established on the Pacific Ocean. It is located northeast of San Francisco in Vallejo, California. The Napa River goes through the Mare Island Strait and separates the peninsula shipyard (Mare Island, California) from the main portion of the city of Vallejo. MINSY made a name for itself as the premier U.S. West Coast submarine port as well as serving as the controlling force in San Francisco Bay Area shipbuilding efforts during World War II. The base closed in 1996 and has gone through several redevelopment phases. It was registered as a California Historical Landmark in 1960, and parts of it were declared a National Historic Landmark District in 1975. Beginnings In September 1849, Lieutenant Commander William Pope McArthur was placed in command of the US survey schooner ''Ewing'', which had been brought around Cape Horn to the West Coast by Lieutenant Washington Allon Bartlett.

Ship Commissioning
Ship commissioning is the act or ceremony of placing a ship in active service and may be regarded as a particular application of the general concepts and practices of project commissioning. The term is most commonly applied to placing a warship in active duty with its country's military forces. The ceremonies involved are often rooted in centuries-old naval tradition. Ship naming and launching endow a ship hull with her identity, but many milestones remain before she is completed and considered ready to be designated a commissioned ship. The engineering plant, weapon and electronic systems, galley, and other equipment required to transform the new hull into an operating and habitable warship are installed and tested. The prospective commanding officer, ship's officers, the petty officers, and seamen who will form the crew report for training and familiarization with their new ship. Before commissioning, the new ship undergoes sea trials to identify any deficiencies needing corre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Japanese Submarine I-29
''I-29'', code-named ''Matsu'' (松, Japanese for "pine tree"), was a B1 type submarine of the Imperial Japanese Navy used during World War II on two secret missions with Germany. She was sunk while returning from the second mission. Construction This was the most numerous class of Japanese submarines – almost 20 were built, of which only one () survived. These boats were fast, had a long range, and carried a seaplane, launched via a forward catapult. The keel of ''I-29'' was laid on 20 September 1939 at the Yokosuka Naval Arsenal and launched on 29 September 1940. She was commissioned on 27 February 1942, into the 14th submarine squadron under the command of Lieutenant Commander (later Captain) Izu Juichi (伊豆壽市). Yanagi missions The Yanagi missions fell under the Tripartite Pact which provided for an exchange of personnel, strategic materials and manufactured goods between Germany, Italy and Japan. Initially, cargo ships were used to make the exchanges, but when th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wake (physics)
In fluid dynamics, a wake may either be: * the region of recirculating flow immediately behind a moving or stationary blunt body, caused by viscosity, which may be accompanied by flow separation and turbulence, or * the wave pattern on the water surface downstream of an object in a flow, or produced by a moving object (e.g. a ship), caused by density differences of the fluids above and below the free surface and gravity (or surface tension). Viscosity The wake is the region of disturbed flow (often turbulent) downstream of a solid body moving through a fluid, caused by the flow of the fluid around the body. For a blunt body in subsonic external flow, for example the Apollo or Orion capsules during descent and landing, the wake is massively separated and behind the body is a reverse flow region where the flow is moving toward the body. This phenomenon is often observed in wind tunnel testing of aircraft, and is especially important when parachute systems are involved, because ...

Destroyer
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 o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bashi Channel
The Bashi Channel is a waterway between Y'Ami Island of the Philippines and Orchid Island of Taiwan. It is a part of the Luzon Strait in the Pacific Ocean. It is characterized by windy storms during the rainy period, June to December. The Bashi Channel is an important passage for military operations. Both the Philippines and Taiwan dispute the ownership of the waters because both sides say the region lies within 200-nautical-mile from their shores. The channel is also significant to communication networks. Many of the undersea communication cables that carry data and telephone traffic between Asian countries pass through the Bashi Channel, making it a major potential point of failure for the Internet. In December 2006, a magnitude 6.7 submarine earthquake cut several undersea cables at the same time, causing a significant communications bottleneck that lasted several weeks.PINR reportTaiwan Quake Exposes Internet Vulnerability, published 15 January 2007 See also * 2006 Hengch ...

Luzon Strait
The Luzon Strait (Tagalog: ''Kipot ng Luzon'', ) is the strait between Taiwan and Luzon island of the Philippines. The strait thereby connects the Philippine Sea to the South China Sea in the western Pacific Ocean. This body of water is an important strait for shipping and communications. Many ships from the Americas use this route to go to important East Asian ports. Many submarine communications cables pass through the Luzon Strait. These cables provide important data and telephony services to mainland China, Hong Kong, Taiwan, Japan and South Korea. Description The Luzon Strait is approximately wide containing a number of islands belonging to the Philippines that are grouped into two: the islands comprising the province of Batanes and the Babuyan Islands, which are part of the province of Cagayan. The strait is divided into a number of smaller channels. The Babuyan Channel separates Luzon from the Babuyan Islands, which is separated from Batanes by the Balintang Chann ...

Mariana Islands
The Mariana Islands (; also the Marianas; in Chamorro: ''Manislan Mariånas'') are a crescent-shaped archipelago comprising the summits of fifteen longitudinally oriented, mostly dormant volcanic mountains in the northwestern Pacific Ocean, between the 12th and 21st parallels north and along the 145th meridian east. They lie south-southeast of Japan, west-southwest of Hawaii, north of New Guinea and east of the Philippines, demarcating the Philippine Sea's eastern limit. They are found in the northern part of the western Oceanic sub-region of Micronesia, and are politically divided into two jurisdictions of the United States: the Commonwealth of the Northern Mariana Islands and, at the southern end of the chain, the territory of Guam. The islands were named after the influential Spanish queen Mariana of Austria following their colonization in the 17th century. The indigenous inhabitants are the Chamorro people. Archaeologists in 2013 reported findings which indicated that the ... [...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 ...
