Flank speed. Flank speed is an American nautical term referring to a ship 's true maximum speed but it is not equivalent to the term full speed ahead. Usually, flank speed is reserved for situations in which a ship finds itself in imminent danger, such as coming under attack by aircraft. Flank speed is very demanding of fuel and often ...
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.
Designed burst speed in tests was 43–45 kn (49–52 mph; 80–83 km/h) for all vessels, and speeds of 41–42 kn (47–48 mph; 76–78 km/h) could be sustained. Acceleration to top speed took one minute and reversing 180 degrees at full speed took just 40 seconds.

Seawolf. -class submarine. 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.
On 8 January 2005 at 02:43 GMT, San Francisco allided with an undersea mountain about 364 nautical miles (675 km) southeast of Guam while operating at flank (maximum) speed at a depth of 525 feet (160 m). Official US Navy reporting subsequent to the grounding cited the location as "in the vicinity of the Caroline Islands". [4]
Sonar (sound navigation and ranging or sonic navigation and ranging) [2] is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigate, measure distances (ranging), communicate with or detect objects on or under the surface of the water, such as other vessels.
