No. 428 Squadron RCAF
No. 428 Squadron RCAF was the ninth long-range heavy bomber Article XV squadron formed overseas during the Second World War at RAF Dalton in Yorkshire, England on November 7, 1942. The squadron was initially assigned to No. 4 Group RAF. With the creation of No. 6 Group RCAF, the squadron was reallocated on January 1, 1943 operating with it until April 25, 1945.
No. 482 Squadron RAAF
No. 4 Repair and Salvage Unit (RSU) was formed at RAAF Station Laverton, Victoria, on 18 May 1942. Its inaugural commanding officer, from 1 June, was acting Flight Lieutenant H.R.P. Relf. On 20 October, it commenced a move to Pell Airfield, Northern Territory, becoming operational on 26 December. Coming under the control of North-Western Area Command (NWA), No. 4 RSU was responsible for salvaging damaged aircraft, which it subsequently repaired or dismantled for spare parts. By December 1943, its strength was over 500 officers and men. It was renamed No. 4 Repair and Servicing Unit on 1 January 1945, and re-located to Winnellie, Northern Territory, on 11 May. As the war in the Pacific moved northward, No. 4 RSU's strength was reduced; by August it was under 400, including 11 officers. On 15 December 1945, it moved to RAAF Station Parkes, New South Wales. The unit re-located from Parkes to RAAF Station Amberley, Queensland, on 15 April 1946.
No. 4 RSU re-formed as No. 482 (Maintenance) Squadron on 10 May 1946. Commanded by Squadron Leader J.E. Jackson, it became a component of No. 82 (Bomber) Wing. The squadron's motto was "Trenchant". No. 82 Wing's flying complement included Nos. 12, 21, and 23 Squadrons, but these were renumbered Nos. 1, 2 and 6 Squadrons respectively in February 1948. At the same time, the wing's Consolidated B-24 Liberator heavy bombers were replaced by Avro Lincolns. During 1949–50, some of the Lincolns were specially modified with advanced radar and other instrumentation to participate in Operation Cumulative, a joint program with the Royal Air Force gathering long-range navigation and bombing data for use in potential air campaigns against the Soviet Union. No. 482 Squadron faced a critical shortage of Merlin engines in mid-1950, but the situation improved the next year.
