The 3rd Flotilla was re-equipped with A-class destroyers in 1930, and "Wild Swan" was placed in reserve. She was re-commissioned in 1931, joining the 8th Destroyer Flotilla on the China Station. "Wild Swan" transferred to the 1st Destroyer Flotilla based at Singapore in December 1934. The flotilla transferred to the Mediterranean during the Abyssinian crisis. The outbreak of the Spanish Civil War in July 1936 saw "Wild Swan" at Gibraltar and on 23 July she was patrolling in the Straits of Gibraltar when she was near missed by bombs dropped by Nationalist bombers, which resulted in "Wild Swan" firing back at the aircraft. Between 25 and 28 July she took part in the evacuation of civilians from Huelva, and then returned to the United Kingdom, reaching Spithead on 31 July. "Wild Swan" then joined the Local Defence Flotilla at Portsmouth, taking part in the Coronation Fleet Review for King George VI on 20 May 1937.
