August to South East Asia for service in the Vietnam War as RAAF Transport Flight Vietnam (RTFV). The same month, No. 86 Wing was disbanded. Because the Caribous were primarily for support of the Australian Army, an overarching wing headquarters for the Caribous and Hercules was now considered inappropriate. No. 486 Squadron was also disbanded and its equipment and staff divided between Nos. 36 and 38 Squadrons, which along with AMTF became independently operating units under the command of Headquarters RAAF Base Richmond. Following the re-establishment at Richmond of No. 37 Squadron in February 1966, flying C-130E Hercules, No. 486 Squadron was re-formed to provide maintenance for both Hercules squadrons. As No. 36 Squadron's tasking was mainly tactical and No. 37 Squadron's strategic (owing to the longer range of its C-130Es), forming the Hercules units into a new wing was not deemed necessary. Still based at Richmond, the Hercules provided long-range transport and medical evacuation services to and from South East Asia during the Vietnam War. No. 36 Squadron's C-130As were replaced by C-130H models in 1978. RTFV was re-formed as No. 35 Squadron in June 1966, and continued to serve in Vietnam until Australian forces were withdrawn in 1972; it was then based in Richmond until 1976, when it relocated to RAAF Base Townsville, Queensland. No. 38 Squadron meanwhile continued to operate Caribous out of Richmond until 1992, when it transferred to RAAF Base Amberley, Queensland. In the Vietnam and post-Vietnam eras, along with their military transport duties, the Hercules and Caribou undertook disaster relief operations throughout Australia and the Pacific. Current transport formation (1987–) No. 86 Wing re-formed at Richmond on 2 February 1987, under the newly established Air Lift Group (ALG), which replaced Headquarters RAAF Base Richmond. Commanded by Group Captain G.I. Lumsden, the wing's flying units consisted of No. 33 Squadron, operating Boeing 707 tanker-transports, and Nos. 36 and 37 Squadrons, operating C-130H and C-130E Hercules, respectively; No. 486 Maintenance Squadron and Air Movements Training and Development Unit (AMTDU), which had evolved from AMTF in 1965, were also under its control. No. 486 Squadron was responsible for day-to-day maintenance of the 707s as well as the Hercules. No. 34 Squadron, the VIP transport unit based at RAAF Base Fairbairn in Canberra, and No. 32 Squadron, flying Hawker Siddeley HS 748 air navigation trainers at RAAF Base East Sale in Victoria, became part of No. 86 Wing
