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 unsustainable because ...
The engineers hear the bell and move their handle to the same position to signal their acknowledgment of the order, and adjust the engine speed accordingly. Such an order is called a "bell"; for example, the order for a ship's maximum speed, flank speed, is called a "flank bell".
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.
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 ...
A chip log consists of a wooden board attached to a line (the log-line ). The log-line has a number of knots at uniform intervals. The log-line is wound on a reel so the user can easily pay it out . Over time, log construction standardized. The shape is a quarter circle, or quadrant with a radius of 5 inches (130 mm) or 6 inches (150 mm), [1 ...
2,700+ killed and wounded [2] The Battle off Samar was the centermost action of the Battle of Leyte Gulf, one of the largest naval battles in history, which took place in the Philippine Sea off Samar Island, in the Philippines on October 25, 1944. It was the only major action in the larger battle in which the Americans were largely unprepared.
Background. As a ship moves in the water, it creates standing waves that oppose its movement.This effect increases dramatically in full-formed hulls at a Froude number of about 0.35 (which corresponds to a speed/length ratio (see below for definition) of slightly less than 1.20 knot·ft −½) because of the rapid increase of resistance from the transverse wave train.
This ship has a flank speed of 50 knots (93 km/h; 58 mph) but can travel only 1,500 nautical miles (2,800 km; 1,700 mi) at flank speed, exhausting its fuel in 30 hours. Thus, its "flank speed" consumes fuel over seven times faster than the most economic speed.
