 She was powered by Parsons geared steam turbines, driving four propeller shafts. Steam was provided by eight Admiralty boilers which normally delivered 100,000 shaft horsepower (75,000 kW), but could deliver 110,000 shp (82,000 kW) at emergency overload. This gave Prince of Wales a top speed of 28 knots (52 km / h; 32 mph). The ship carried 3,542 long tons (3,600 t) of fuel oil. She also carried 180 long tons (200 t) of diesel oil, 256 long tons (300 t) of reserve feed water and 444 long tons (500 t) of freshwater. During full power trials on 31 March 1941, Prince of Wales at 42,100 tons displacement achieved 28 knots with 111,600 shp at 228 rpm and a specific fuel consumption of 0.73 lb per shp.Prince of Wales had a range of 3,100 nautical miles (5,700 km; 3,600 mi) at 27 knots (50 km / h; 31 mph).
