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.
HMS Ambuscade was a British Royal Navy destroyer which served in the Second World War. She and her Thornycroft competitor, HMS Amazon, were prototypes designed to exploit advances in construction and machinery since World War I and formed the basis of Royal Navy destroyer evolution up to the Tribal of 1936.
HMS Ambuscade was an Acasta-class destroyer of the Royal Navy and was launched in 1913. She served throughout the First World War, forming part of the Grand Fleet and taking part at the Battle of Jutland, serving in the Dover Patrol and spending the latter part of the war as a convoy escort.

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 Ambuscade.

The Mirabello class were a group of three destroyers(originally scout cruisers) built for the Regia Marina during World War I. Carlo Alberto Racchia was sunk by a mine in the Black Sea during the Allied intervention in the Russian Civil War in 1920. The remaining two ships, obsolescent by 1938, were re-rated as destroyers and participated in World War II. Carlo Mirabello was also lost to a mine while escorting a convoy in 1941. The last surviving ship, Augusto Riboty, was reconfigured as a convoy escort in 1942–1943. The torpedo tubes were removed and depth charges and 20 mm (0.79 in) anti-aircraft guns added. She survived the war and was transferred to the Soviet Union as war reparations in 1946. The ship was scrapped five years later.

ARC Antioquia was the name ship of her class of two destroyers built during the 1930s for the Armada Nacional República de Colombia. Originally ordered by the Portuguese Navy, they were purchased by Colombia while still under construction. Antioquia was discarded in 1960 and subsequently scrapped.
The Antioquia class of destroyers consisted of two ships, ARC Antioquia and ARC Caldas, used by the navy of Colombia, the Armada Nacional República de Colombia, between 1934 and 1961. Initially constructed at the Lisbon Naval Arsenal as part of the Portuguese Navy's Douro class, they were acquired by Colombia before completion in response to the Peruvian purchase of two destroyers during the war with Peru. They arrived too late to see service in the conflict and saw little action during their service lives. They underwent a major refit in the mid-1950s which saw their armament completely redone. Following their removal from service in 1961, they were broken up for scrap.
