HMS Acasta was one of eight A-class destroyers built for the Royal Navy (RN) in the 1920s. The ship spent most of the 1930s assigned to the Mediterranean Fleet. During the early months of the Spanish Civil War of 1936–1939, Acasta spent considerable time in Spanish waters enforcing the arms blockade imposed by Britain and France on both sides of the conflict.

The A- and B-class destroyers were a group of 18 destroyers built for the Royal Navy during the late 1920s, with two additional ships built for the Royal Canadian Navy. The British ships were divided into two flotillas of eight destroyers, each with a flotilla leader.
