The first C-47s in RLAF service were 6 aircraft taken over from the Aviation Laotienne. The venerable C-47s provided the mainstay of the RLAF airlift and transport capability. Additional aircraft from the USA brought the total to 16 aircraft by late 1968. Eight aircraft were obtained from the SVNAF in 1969 and three of these were not converted into gunships. By late 1970, the RLAF is reported to have had 34 C-47s on strength, including 9 AC-47s. At least one aircraft was provided by Australia in 1971. Between 1973 and 1975, some were transferred to Thailand, with s/n 45-1127 entering service with the Royal Thai Navy.
