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 ...
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 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.
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 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.
The Los Angeles class of submarines are nuclear-powered fast attack submarines ( SSN) in service with the United States Navy. Also known as the 688 class (pronounced "six-eighty-eight") after the hull number of lead vessel USS Los Angeles (SSN-688), 62 were built from 1972 to 1996, the latter 23 to an improved 688i standard.
1 × 5-inch (127 mm) / 25 caliber deck gun [4] Bofors 40 mm and Oerlikon 20 mm cannon. The Balao class was a design of United States Navy submarine used during World War II, and with 120 [2] boats completed, the largest class of submarines in the United States Navy. An improvement on the earlier Gato class, the boats had slight internal ...
Hull speed. Hull speed or displacement speed is the speed at which the wavelength of a vessel's bow wave is equal to the waterline length of the vessel. As boat speed increases from rest, the wavelength of the bow wave increases, and usually its crest-to-trough dimension (height) increases as well. When hull speed is exceeded, a vessel in ...
