[citation needed] Following the completion of repairs from mine damage, Warwick recommissioned into the 14th Destroyer Flotilla on 12 January 1919.

[21] On 26 September 1922, as the Chanak Crisis threatened war between Britain and Turkey, the First Destroyer Flotilla, including Warwick, left England for the Mediterranean, arriving at Çanakkale on 4 October,[22] remaining there until March 1923.

[9] On 26 June 1924, Warwick took part in the Fleet Review at Spithead by King George V, leading the First Destroyer Flotilla in the absence of the normal leader Wallace.

[30] By the time of the Second World War, it was recognised that the V- and W-class destroyers were unsuitable for front-line fleet operations and they were deployed on anti-submarine and convoy escort duties.

[31] In September 1939 Warwick was allocated to the 11th Destroyer Flotilla, based at Devonport and part of Western Approaches Command.

[9] On 15–16 June 1940, Warwick and the destroyer Witch reinforced the escort of the convoy US.3, consisting of the troopships Andes, Aquitania, Empress of Britain, Empress of Canada, Mauretania and Queen Mary, carrying 14,000 Australian and New Zealand troops on the last part of the convoy's voyage to Britain.

[42] In late September to early November 1943, the destroyer took Operation Alacrity, the establishment and supply of Allied air bases in the Azores which served to close the Mid-Atlantic gap, with Warwick escorting convoys carrying airmen and supplies to set up the air bases.

[9] In January 1944, having returned to Britain, Warwick was assigned to lead an escort group operating in the Southwest Approaches, guarding against attacks by German S-boats and submarines.

On 20 February, Warwick was hit on the stern by a torpedo fired by the German submarine U-413,[c] 20 nmi (23 mi; 37 km) southwest of Trevose Head.
