The C class was a class of 32 destroyers of the Royal Navy that were launched from 1943 to 1945. The class was built in four flotillas of 8 vessels, the Ca, Ch, Co and Cr classes, ordered as the 11th, 12th, 13th and 14th Emergency Flotillas respectively. The class names are derived from the initial 2 letters of the member ships' names, although the Ca class were originally ordered with a heterogeneous mix of traditional destroyer names. A fifth flotilla, the Ce class, was planned but were cancelled in favour of the Weapon class destroyers.



They were built as part of the War Emergency Programme, based on the hull and machinery of the pre-war J class, incorporating whatever advances in armament and naval radar were available at the time. Some of the class were completed in time for wartime service. All ships used the Fuze Keeping Clock High Angle Fire Control Computer.[1]

The Ca flotilla were generally repeats of the preceding W and Z class, while the Ch, Co and Cr flotillas had quadruple instead of pentuple torpedo tubes to compensate for the added weight of remote power control (RPC) gunlaying equipment. They also introduced the all-welded hull into Royal Navy destroyer construction, beginning in Contest.

Caprice was the last destroyer built for the Royal Navy to be fitted with the ubiquitous quadruple QF 2 pounder "pom-pom" mounting Mark VII. Comet and Contest were fitted as minelayers, and lacked 'Y' 4.5 inch gun.

The Ca flotilla were reconstructed in the 1960s to serve as fast fleet escorts.
