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 ...

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] |
Operation Torch
Operation Torch (8–16 November 1942) was an Allies of World War II, Allied invasion of French North Africa during the Second World War. Torch was a compromise operation that met the British objective of securing victory in North Africa while allowing American armed forces the opportunity to begin their fight against Nazi Germany and Fascist Italy on a limited scale. The French colonies were aligned with Germany via Vichy France but the loyalties of the population were mixed. Reports indicated that they might support the Allies. The American General Dwight D. Eisenhower, supreme commander of the Allied forces in Mediterranean and Middle East theatre of World War II, Mediterranean theater of the war, approved plans for a three-pronged attack on Casablanca (Western), Oran (Centre) and Algiers (Eastern), then a rapid move on Tunis to catch Axis forces in North Africa from the west in conjunction with the British advance from Egypt. The Western Task Force encountered unexpected ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
USS Massachusetts (BB-59)
USS ''Massachusetts'' (BB-59) is the third of four fast battleships built for the United States Navy in the late 1930s. The first American battleships designed after the Washington treaty system began to break down in the mid-1930s, they took advantage of an escalator clause that allowed increasing the main battery to guns, but refusal to authorize larger battleships kept their displacement close to the Washington limit of . A requirement to be armored against the same caliber of guns as they carried, combined with the displacement restriction, resulted in cramped ships, a problem that was exacerbated by wartime modifications that considerably strengthened their anti-aircraft batteries and significantly increased their crews. On completion, ''Massachusetts'' was sent to support Operation Torch, the invasion of French North Africa, in November 1942. There, she engaged in an artillery duel with the incomplete French battleship and neutralized her. ''Massachusetts'' thereafter ...

Presidential Unit Citation (United States)
The Presidential Unit Citation (PUC), originally called the Distinguished Unit Citation, is awarded to units of the uniformed services of the United States, and those of allied countries, for extraordinary heroism in action against an armed enemy on or after 7 December 1941 (the date of the Attack on Pearl Harbor and the start of American involvement in World War II). The unit must display such gallantry, determination, and ''Esprit de Corps (morale), esprit de corps'' in accomplishing its mission under extremely difficult and hazardous conditions so as to set it apart from and above other units participating in the same campaign. Since its inception by President Franklin D. Roosevelt with the signing of s:Executive Order 9075, Executive Order 9075 on 26 February 1942, Retroactive legislation, retroactive to 7 December 1941, to 2008, the Presidential Unit Citation has been awarded in conflicts such as World War II, the Korean War, the Vietnam War, Iraq War, and the War in Afgh ...

Circumnavigation
Circumnavigation is the complete navigation around an entire island, continent, or astronomical object, astronomical body (e.g. a planet or natural satellite, moon). This article focuses on the circumnavigation of Earth. The first circumnavigation of the Earth was the Magellan's circumnavigation, Magellan Expedition, which sailed from Sanlucar de Barrameda, Spain in 1519 and returned in 1522, after crossing the Atlantic Ocean, Atlantic, Pacific Ocean, Pacific, and Indian Ocean, Indian oceans. Since the rise of commercial aviation in the late 20th century, circumnavigating Earth is straightforward, usually taking days instead of years. Today, the challenge of circumnavigating Earth has shifted towards human and technological endurance, speed, and List of circumnavigations#Miscellaneous, less conventional methods. Etymology The word ''circumnavigation'' is a noun formed from the verb ''circumnavigate'', from the past participle of the Latin verb ''circumnavigare'', from ''circum ...

Submarine
A submarine (often shortened to sub) is a watercraft capable of independent operation underwater. (It differs from a submersible, which has more limited underwater capability.) The term "submarine" is also sometimes used historically or informally to refer to remotely operated vehicles and Autonomous underwater vehicle, robots, or to medium-sized or smaller vessels (such as the midget submarine and the wet sub). Submarines are referred to as ''boats'' rather than ''ships'' regardless of their size. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and submarines were adopted by several navies. They were first used widely during World War I (1914–1918), and are now used in many navy, navies, large and small. Their military uses include: attacking enemy surface ships (merchant and military) or other submarines; aircraft carrier protection; Blockade runner, blockade running; Ballistic missile submarine, nuclear deterrenc ...

Nuclear Power
Nuclear power is the use of nuclear reactions to produce electricity. Nuclear power can be obtained from nuclear fission, nuclear decay and nuclear fusion reactions. Presently, the vast majority of electricity from nuclear power is produced by nuclear ''fission'' of uranium and plutonium in nuclear power plants. Nuclear ''decay'' processes are used in niche applications such as radioisotope thermoelectric generators in some space probes such as ''Voyager 2''. Reactors producing controlled fusion power, ''fusion'' power have been operated since 1958 but have yet to generate net power and are not expected to be commercially available in the near future. The first nuclear power plant was built in the 1950s. The global installed nuclear capacity grew to 100GW in the late 1970s, and then expanded during the 1980s, reaching 300GW by 1990. The 1979 Three Mile Island accident in the United States and the 1986 Chernobyl disaster in the Soviet Union resulted in increased regulation and p ...

USS Triton (SSRN-586)
USS ''Triton'' (SSRN/SSN-586), the only member of her class, was a nuclear powered radar picket submarine in the United States Navy. She was the only Western submarine powered by two nuclear reactors. ''Triton'' was the second submarine and the fourth vessel of the United States Navy to be named for the Greek god Triton. This naming convention was unusual at the time; U.S. Navy submarines were usually named for various species of fish. At the time of her commissioning in 1959, ''Triton'' was the largest, most powerful, and most expensive submarine ever built at $109 million (equivalent to $ billion in ) excluding the cost of nuclear fuel and reactors. ''Tritons shakedown cruise in early 1960 saw her become the first vessel to execute a submerged circumnavigation of the Earth, in Operation Sandblast. The voyage was made under the command of Captain Edward L. "Ned" Beach Jr. ''Triton''s mission as a radar picket submarine was made obsolete after two years by the intr ...

Redline
The redline is the maximum engine speed at which an internal combustion engine or traction motor and its components are designed to operate without causing damage to the components themselves or other parts of the engine. The redline of an engine depends on various factors such as stroke, mass of the components, displacement, composition of components, and balance of components. Redlining is riding or driving an automotive vehicle above the redline. The actual term ''redline'' comes from the red bars that are displayed on tachometers in cars starting at the rpm that denotes the redline for the specific engine. Straying into this area usually does not mean instant engine failure, but may increase the chances of damaging the engine. Variation of redline The acceleration, or rate of change in piston velocity, is the limiting factor. The piston acceleration is directly proportional to the magnitude of the G-forces experienced by the piston-connecting rod assembly. As long as the ...
