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 ...
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".
Heermann steamed into the action at flank speed through the formation of "baby flattops" through smoke and intermittent rain squalls that had reduced visibility at times to less than 100 yd (91 m), twice having to back emergency full to avoid collisions with friendly ships, first with Samuel B. Roberts and then at 07:49 with Hoel, as she tried ...
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. —EncMstr 17:41, 21 November 2014 (UTC) Reply
The Ise-class ships had two sets of direct-drive steam turbines, each of which drove two propeller shafts, using steam provided by 24 Kampon Ro Gō water-tube boilers. The turbines were designed to produce a total of 45,000 shaft horsepower (34,000 kW) and give the ships a speed of 23 knots (43 km/h; 26 mph).
These were intended to provide a top speed of 14 knots (26 km/h; 16 mph), although 12 knots (22 km/h; 14 mph) was a more realistic flank speed. The landing ships were capable of transporting 197 troops, and were equipped with three LCVPs and one LCPL. The ship's company was 190-strong, and consisted of about six or seven line officers, a supply ...
In the expansion Flank Speed, the set checklist lists Voroshilov as part of the Soviet forces, but the actual ship included in the set is Kirov. Both are Kirov -class heavy cruisers of the same series and are considered sister ships.
