One-third and two-thirds are fractions of standard speed. Full is greater than standard but not as great as flank. In surface ship nuclear marine propulsion, the difference between full speed and flank speed is of lesser significance, because vessels can be run at or very near their true maximum speed for a long time with little regard for fuel ...
Underwater speed record. Underwater speed record include records for submarines, autonomous underwater vehicles, and torpedoes. As these are typically for military vehicles, most are unconfirmed. The USS Albacore, with its teardrop hull, is claimed to have reached an underwater speed of 33 knots (61 km/h; 38 mph).
A AAW An acronym for anti-aircraft warfare. aback (of a sail) Filled by the wind on the opposite side to the one normally used to move the vessel forward.On a square-rigged ship, any of the square sails can be braced round to be aback, the purpose of which may be to reduce speed (such as when a ship-of-the-line is keeping station with others), to heave to, or to assist moving the ship's head ...
Engine order telegraph. An engine order telegraph or E.O.T., also referred to as a Chadburn, [1] is a communications device used on a ship (or submarine) for the pilot on the bridge to order engineers in the engine room to power the vessel at a certain desired speed.
The Sentinel-class cutter, also known as the Fast Response Cutter due to its program name, is part of the United States Coast Guard 's Deepwater program. [2] [3] [4] At 154 feet (46.8 m), it is similar to, but larger than, the 123-foot (37 m) lengthened 1980s-era Island-class patrol boats that it replaces.
Fleet submarine. A fleet submarine is a submarine with the speed, range, and endurance to operate as part of a navy's battle fleet. Examples of fleet submarines are the British First World War era K class and the American World War II era Gato class . The term has survived in Britain to refer to modern nuclear-powered attack submarines.
The Seawolf class is a class of nuclear-powered, fast attack submarines (SSN) in service with the United States Navy. The class was the intended successor to the Los Angeles class, and design work began in 1983. [10] A fleet of 29 submarines was to be built over a ten-year period, but that was reduced to 12 submarines.
The DUBV 43C towed array sonar of La Motte-Picquet.. A towed array sonar is a system of hydrophones towed behind a submarine or a surface ship on a cable. Trailing the hydrophones behind the vessel, on a cable that can be kilometers long, keeps the array's sensors away from the ship's own noise sources, greatly improving its signal-to-noise ratio, and hence the effectiveness of detecting and ...
