Vessels typically contained several engines for different purposes. Main, or propulsion engines are used to turn the ship's propeller and move the ship through the water. . The fire room got its name from the days when ships burned coal to heat steam to drive the steam engines or turbines; the room was where the stokers spent their days shoveling coal continuously onto the grates under the ...
HMS Amazon was a prototype design of destroyer ordered for the Royal Navy in 1924. She was designed and built by Thornycroft in response to an Admiralty request for a new design of destroyer incorporating the lessons and technological advances of the First World War. Their great rivals Yarrow produced a similar, competitive design — that of ...
The design was intended as a smaller follow-on from the preceding Tribal class. In a departure from all previous Royal Navy destroyers, the design used a two boiler room layout. This reduced hull length and allowed for a single funnel, both reducing the profile and increasing the arcs of fire of the light anti-aircraft (AA) weapons. It also ...
Technical drawing of the Fletcher-class destroyer Launch of Fletcher and Radford, 3 May 1942 World War II Destroyer Shipbuilders map from Department of Defense (DoD) The Fletcher class was the first generation of destroyers designed after the series of naval treaties that had limited ship designs heretofore.
The uptakes of the two forward boiler rooms were trunked together aft of the break in the forecastle into the fore funnel while the rear boiler room exhausted into the smaller rear funnel. Both funnels were inclined to the rear to reduce the amount of smoke that might reach the bridge. A tripod mast was fitted between the bridge and the fore ...
Daring was on the end of the line with HMS Diana on her starboard side. When the 'Execute' order was received, Diana failed to respond and Daring turned directly at her. The first lieutenant was on the bridge with the Capt. in the radar plot room. I was i/c 'B' boiler room and saw the repeater telegraph move to "Full Astern".
In these two ships, the position of the boiler rooms was reversed, with the two-boiler room forward and the single unit aft. As a result, the funnel arrangements were transposed, with the thick funnel forwards and the narrow funnel aft. In common with other Thornycroft designs, they had characteristic broad, flat-sided funnels.
The second group, or Ayanami class, were built in 1930 and 1931, and had larger bridges that encompassed the rangefinder, an azimuth compass sighting device and the gun-fire control room, as well as a range finding tower. Furthermore, the boiler room's air inlet was changed from a pipe to a bowl shape.
