context_page_description: No. 21 Squadron is a Royal Australian Air Force general reserve squadron. Formed in the mid-1930s as a unit of the part-time Citizen Air Force, it was mobilised for service during World War II, when it saw action against the Japanese as a fighter unit in the Malayan campaign, a dive bomber unit in the New Guinea campaign, and a heavy bomber unit in the Borneo campaign. After the war, the squadron continued to fly until 1960, when the CAF ceased flying operations. At that time, No. 21 Squadron converted to a non-flying support role, which it currently fulfils at RAAF Williams.
context_section_description: In April 1946, the squadron relocated to RAAF Base Amberley and in December 1947, No. 21 Squadron began to replace its Liberators with Avro Lincoln bombers. An aircraft was lost at Amberley on 19 February 1948, killing all 16 people on board. After being briefly renamed No. 2 Squadron from February to April 1948, the squadron was re-formed as No. 21 (City of Melbourne) Squadron at RAAF Laverton as a Citizen Air Force (reserve) fighter squadron. It flew CAC Wirraway, P-51 Mustang and de Havilland Vampire aircraft from 1948 until 1960. It also operated a Sikorsky S-51 helicopter in a search and rescue role and in 1959 the Wirraways were replaced by Winjeels.
  The squadron ceased flying operations on 2 June 1960, when the role was removed from the CAF's responsibility. It subsequently became a non-flying general reserve squadron headquartered at RAAF Williams near Melbourne. On 1 July 2010, No. 21 (City of Melbourne) Squadron amalgamated with Combat Support Unit Williams to become an integrated Permanent Air Force and Reserve unit responsible for airfield and base support and reserve training.
