    Notes: Other characteristics as per Ca- class

    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" groups or sub-classes, ordered as the 11th, 12th, 13th and 14th Emergency Flotillas respectively. The sub-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" or 15th Emergency Flotilla, was planned but were cancelled in favour of the Weapon class destroyers after only the first two ships had been ordered. The Pennant numbers were all altered from "R" superior to "D" superior at the close of World War II; this involved some renumbering to avoid duplications.

    Design[]

    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.

    Engineering[]

    The class were all fitted with two Admiralty 3-drum boilers with a pressure of 300 lbs/sq.in at 630 degrees F. All had Parsons single-reduction geared turbines, generating 40,000 SHP at 350 RPM, and driving the two shafts to produce a maximum of 36 knots (32 knots under full load condition). All were engined by their builders except Cossack and Constance, which were engined by Parsons. Their bunkers could hold 615 tons of oil fuel, giving them a radius of 4,675 nautical miles at 20 knots (1,400 nautical miles at 32 knots).

    "Ca" (or 11th Emergency) Flotilla[]

    This flotilla was authorised under the 1941 Programme. The first pair was ordered from Yarrow on 16 February 1942; the other six were ordered on 24 March, a pair each from John Brown, Scotts and Cammell Laird. However on 12 August 1942 the contract for the last pair was moved from Cammell Laird to White. Their originally-allocated names were altered to new names beginning with "Ca-" in November 1942. The John Brown pair - Caesar and Cavendish - were fitted as Leaders. On completion they formed the 6th Destroyer Flotilla for service in the Home Fleet. At the end of the war in Europe the flotilla was transferred to the East Indies Fleet and the ships arrived on station between August and November 1945, to late to see service against Japan. They remained in the Indian Ocean until May 1946 when they returned home and paid off into operational reserve. The "Ca" flotilla were reconstructed in the late 1950s and early 1960s to be modernised for anti-submarine warfare and to serve as fast fleet escorts. The superstructure was extended aft, and the bridge was modified; the post-refit bridge differed between the first four conversions (Cavendish, Carron, Cavalier and Carysfort) and the later four (Caprice, Cassandra, Caesar and Cambrian) which were given frigate-type enclosed bridges.

The fourth pair was originally intended to be ordered from Vickers Armstrongs, Walker-on-Tyne, but instead were ordered from Denny on 30 July. The Chequers and Childers were fitted as Leaders.

    "Ce" (or 15th Emergency) Flotilla[]

    Two ships of this putative flotilla, the last of the 26 "Intermediate"-type destroyers authorised under the 1942 Programme, were ordered on 3 February 1942 from White. These two ships were to be named Centaur and Celt. However, with the decision to introduce a fresh design of Intermediate destroyer (which became the Weapon class destroyer design), the White orders were amended to the new design and the names of the two ships were altered to Tomahawk and Sword respectively. The Tomahawk was subsequently renamed again, becoming the Scorpion, while the Sword was finally cancelled on 15 October 1945.
