USNS Josiah Willard Gibbs (T-AGOR-1)
USS ''San Carlos'' (AVP-51) was a built for the United States Navy during World War II. ''San Carlos'', named after San Carlos Bay, Florida, was in commissioned from 1944 to 1947 and earned three battle stars for service in the Pacific during World War II. After eleven years in reserve, ''San Carlos'' was converted to oceanographic research ship USNS ''Josiah Willard Gibbs'' (T-AGOR-1)—named after American scientist Josiah Willard Gibbs—and placed in service as a non-commissioned ship of the Military Sea Transportation Service from 1958 to 1971. In December 1971, the ship was transferred to the Hellenic Navy as ''Hephaistos'' (A413), a motor torpedo boat tender. ''Hephaistos'' was struck from the rolls of the Hellenic Navy in April 1976. Service history World War II: Seaplane tender ''San Carlos'' was laid down on 17 September 1942 by Lake Washington Shipyard at Houghton, Washington.

Oerlikon 20 Mm Cannon
The Oerlikon 20 mm cannon is a series of autocannons based on an original German Becker Type M2 20 mm cannon design that appeared very early in World War I. It was widely produced by Oerlikon Contraves and others, with various models employed by both Allied and Axis forces during World War II. Many versions of the cannon are still used. Blowback-operated models History Origins During World War I, the German industrialist Reinhold Becker developed a 20 mm caliber cannon, known now as the 20 mm Becker using the advanced primer ignition blowback (API blowback) method of operation. This used a 20×70mmRB cartridge and had a cyclic rate of fire of 300 rpm. It was used on a limited scale as an aircraft gun on ''Luftstreitkräfte'' warplanes, and an anti-aircraft gun towards the end of that war. Because the Treaty of Versailles banned further production of such weapons in Germany, the patents and design works were transferred in 1919 to the Swiss firm SEMAG (''Seebach M ...

Nissan Island
Nissan Island (also Green Island or Sir Charles Hardy Island) is the largest of the Green Islands of Papua New Guinea. It is located at , about 200 km east of Rabaul on New Britain and about 200 km north-west of Bougainville. The island is administered under Nissan Rural LLG in the Autonomous Region of Bougainville. Nissan island, along with other nearby islands, has been described as a "stepping stone island" and it is believed that this island plays an important role in helping various plant and animal species spread throughout the region. History Based upon pottery fragments discovered in archeological excavations researchers have determined that the inhabitants of this island commonly engaged in trade with the inhabitants of Buka Island. Commonly traded items would have included pigs, pottery, and shell money. British and American whaling vessels visited the island in the nineteenth century for food, water and wood. The first on record was the ''Addison'' in 183 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Shakedown Cruise
Shakedown cruise is a nautical term in which the performance of a ship is tested. Generally, shakedown cruises are performed before a ship enters service or after major changes such as a crew change, repair, refit or overhaul. The shakedown cruise simulates working conditions for the vessel, for various reasons. For most new ships, the major reasons are to familiarise a crew with a new vessel and to ensure all of the ship's systems are functional. Overview If the ship is the first of its class, it will likely also be performing its sea trials, a test of its performance. In this context, 'shakedown cruise' and 'sea trials' may be used interchangeably, though each has a slightly different meaning. In such a case, it is likely that the ship's systems will be pushed to redline, or maximum capacity, to demonstrate the class's speed and other important traits. Until bested by another ship of the same class, this shakedown performance will be the standard of the class's capabiliti ...

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 it is completed and considered ready to be designated a commissioned ship. The engineering plant, weapon and Electronics, electronic systems, Galley (kitchen), 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 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ship Naming And Launching
Ceremonial ship launching involves the performing of ceremonies associated with the process of transferring a vessel to the water. It is a nautical tradition in many cultures, dating back millennia, to accompany the physical process with ceremonies which have been observed as public celebration and a solemn blessing, usually but not always, in association with the launch itself. Ship launching imposes stresses on the ship not met during normal operation and in addition to the size and weight of the vessel represents a considerable engineering challenge as well as a public spectacle. The process also involves many traditions intended to invite good luck, such as christening by breaking a sacrificial bottle of champagne over the bow as the ship is named aloud and launched. Methods There are three principal methods of conveying a new ship from building site to water, only two of which are called "launching". The oldest, most familiar, and most widely used is the end-on la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Keel Laying
Laying the keel or laying down is the formal recognition of the start of a shipbuilding, ship's construction. It is often marked with a ceremony attended by dignitaries from the shipbuilding company and the ultimate owners of the ship. Keel laying is one of the four specially celebrated events in a ship's life; the others are Ceremonial ship launching, launching, Ship commissioning, commissioning, and Ship decommissioning, decommissioning. Earlier, the event recognized as the keel laying was the initial placement of the central timber making up the backbone of a vessel, called the keel. As steel ships replaced wooden ones, the central timber gave way to a central steel beam. Modern ships are most commonly built in a series of pre-fabricated, complete hull sections rather than around a single keel. The event recognized as the keel laying is the first joining of modular components, or the lowering of the first module into place in the building dock. It is now often called "keel ...

Aviation Fuel
Aviation fuels are either petroleum-based or blends of petroleum and synthetic fuels, used to power aircraft. They have more stringent requirements than fuels used for ground applications, such as heating and road transport, and they contain additives to enhance or preserve properties important to fuel performance and handling. They are kerosene-based fuels (such as JP-8 and Jet A-1) used in gas-turbine-powered aircraft. Piston-engined aircraft use leaded gasoline, while those with diesel engines may use jet fuel (kerosene). By 2012, all U.S. Air Force aircraft had been certified to use a 50-50 blend of kerosene and synthetic fuel derived from coal or natural gas, in an effort to stabilize fuel costs. Types of aviation fuel Conventional aviation fuels Jet fuel Jet fuel is a clear to straw-colored fuel, based on either an unleaded kerosene (Jet A-1), or a naphtha–kerosene blend (Jet B). Similar to diesel fuel, it can be used in either Diesel engine, compression ignition ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Squadron (aviation)
A squadron in an air force, or naval or army aviation service, is a unit comprising a number of military aircraft and their aircrews, usually of the same type, typically with 12 to 24 aircraft, sometimes divided into three or four flights, depending on aircraft type and air force. In most armed forces, two or more squadrons will form a group or a wing. Some military forces (including the United States Air Force, United States Space Force, French Air and Space Force, Royal Air Force, German Air Force, Royal Netherlands Air Force, Belgian Air Component and Republic of Singapore Air Force) also use the term "squadron" for non-flying ground units (e.g. radar squadrons, missile squadrons, air defense squadrons, aircraft maintenance squadrons, security forces squadrons, civil engineering squadrons, range operations squadrons, range management squadrons, weather squadrons, medical squadrons, etc.).
