In the mid-1920's two destroyer prototypes were built. New technological advances in machinery and construction techniques needed to be exploited. The armament was the same as the World War One vintage Admiralty Modified W-class but there was a new fire control director system installed.

Early in the war these two ships had the after bank of torpedo tubes replaced by a 3" AA gun. Later these ships were modified for escort duties, they landed 'A' and 'Y' 4.7" guns. A hedgehog was fitted, as well as radar and increased anti-aircraft armament.

In July 1943 Ambuscade was fitted with the prototype of the Squid in lieu of the Hedgehog. The remaining bank of torpedo tubes was landed as well as the 3" gun. 65 tons off ballast was fitted instead. Also in 1943 Amazon landed the remaining bank of torpedo tubes and her 3" gun to make room for a ten pattern depth-charge outfit.
