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 ...
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.
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.
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.
Virginia. -class submarine. Only limited by food and maintenance requirements. The Virginia class, or the SSN-774 class, is the newest class of nuclear-powered cruise missile fast attack submarines in service with the United States Navy. The class is designed for a broad spectrum of open-ocean and littoral missions, including anti-submarine ...
These submarines can also be fitted with a dry deck shelter, which allows special forces (e.g. SBS) to deploy whilst the submarine is submerged. [33] More than 39,000 acoustic tiles mask the vessel's sonar signature, part of acoustic qualities that give the Astute class over any other submarine previously operated by the Royal Navy. [34]

She is the fourth submarine of the United States Navy named for the seawolf, a solitary fish with strong, prominent teeth that give it a savage look.
The United States Navy Salmon-class submarines were an important developmental step in the design of the "fleet submarine" concept during the 1930s.An incremental improvement over the previous Porpoise class, they were the first US submarine class to achieve 21 knots with a reliable propulsion plant, allowing them to operate with the Standard-type battleships of the surface fleet.
