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.
The flanking maneuver is a basic military tactic with several variations. Flanking an enemy entails attacking from one or more sides, at an angle to the enemy's direction of engagement. There are three standard flanking maneuvers. The first maneuver is the ambush, where a unit performs a surprise attack from a concealed position.
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 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. 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.
F126 or Niedersachsen-class frigate (Fregatte 126) is a planned German frigate class intended to replace the F123 Brandenburg-class frigates in the German Navy.The ships are to be the largest surface warships to join the German Navy since World War II.
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 ...
The Type 214 is a class of diesel–electric submarines developed exclusively for export by Howaldtswerke-Deutsche Werft GmbH (HDW). [2] It features diesel propulsion with an air-independent propulsion (AIP) system using Siemens polymer electrolyte membrane (PEM) hydrogen fuel cells. The class combines the design principles of the Type 209 ...
