The first USAF unit to be stationed at Cam Ranh AB was the 12th Tactical Fighter Wing, which was assigned on 8 November 1965, being deployed from MacDill Air Force Base, Florida.
With the transfer of jurisdiction of Cam Ranh AB to the 483d Tactical Airlift Wing, the 12th TFW was reassigned to Phù Cát Air Base where it replaced the 37th TFW in a name-only change.
