HMS Comet was one of thirty-two C-class destroyers built for the Royal Navy during the Second World War, a member of the eight-ship Co sub-class.

The turbines developed a total of 40,000 indicated horsepower (30,000 kW) and gave a speed of 36 knots (67 km/h; 41 mph) at normal load.

[2] During her sea trials, Comet reached a speed of 31.8 knots (58.9 km/h; 36.6 mph) at a load of 2,200 long tons (2,200 t).

[3] The Co sub-class carried enough fuel oil to give them a range of 4,675 nautical miles (8,658 km; 5,380 mi) at 20 knots (37 km/h; 23 mph).

[1][6] On commissioning Comet worked up at Scapa Flow, before carrying out occupation duties at Wilhelmshaven in Germany in August and October 1945, before leaving for the Far East for service with the British Pacific Fleet, arriving at Kure, Japan in February 1946.
