No. 1 Aircraft Depot (No. 1 AD) was a Royal Australian Air Force (RAAF) maintenance unit formed in July 1921 at RAAF Point Cook, then moved to nearby RAAF Laverton in 1926. In addition to servicing aircraft and equipment, it helped with survey flights across Australia and the Pacific early on and trained maintenance staff. Its workforce grew from about 350 people in the 1930s to more than 2,000 in World War II, when it assembled, tested, and repaired aircraft such as Tiger Moths, Spitfires, and B-17 bombers, and carried out aircraft research and development. Soon after the war, it introduced the first jets into RAAF service. In 1961 it stopped maintaining airframes but continued servicing aero engines, and by the 1970s it mainly focused on ground-based equipment. No. 1 AD was disbanded in December 1994, with its work taken over by other units and private contractors, and it had been the oldest RAAF unit still operating continuously at that time. No. 1 Aircraft Depot was one of the first RAAF units formed after the service started in March 1921. It began in Melbourne, then moved to a purpose-built base at Laverton near rail lines in 1926, because Point Cook’s seaside conditions and lack of transport infrastructure were not ideal for aircraft work. The depot ran aircraft and engine repair, helped assemble and test equipment, and supported survey and research flights, including Northern and Papuan surveys in the late 1920s. By the mid-1930s it had hundreds of staff, handled many aircraft types, and expanded into recruit training, later helping develop future RAAF training and technical programs, while also modifying aircraft for Antarctic rescue work in 1935. During World War II, No. 1 Aircraft Depot RAAF at Laverton mainly served as a key aircraft depot, expanding after hostilities began to assemble, test, ferry and maintain training and combat aircraft, and even repair damaged US aircraft. It was organised under Southern Area Command and later No. 4 Maintenance Group, and supported RAAF operations across areas such as northern Australia and New Guinea. The depot also carried out research and performance testing on aircraft like the Spitfire and Boomerang, including solving problems found during trials, and by January 1945 it employed 2,339 staff. After the war, No. 1 Aircraft Depot helped bring the first jet aircraft into RAAF service, including assembling Australia’s first de Havilland Vampire jet and receiving early helicopters. It also supported important VIP and air-racing tasks, later taking delivery of key jet aircraft such as the English Electric Canberra and the Sabre. As the RAAF reorganised and its work shifted away from aircraft maintenance, No. 1 AD increasingly focused on ground support and communications, including radar and telecommunications equipment. In later years it helped test and develop technology for aircraft like the F-111 and F/A-18, and despite restructuring and outsourcing, received the Queen’s Colour in 1981 before being disbanded in 1994 as one of the longest-running maintenance depots. No. 1 Aircraft Depot RAAF had a series of commanding officers, each leading the depot during their period of command. The text then introduces that list of officers who served as commanders.
