In response to what has become known as the Gulf of Tonkin incident in 1964, TAC pilots and support personnel found themselves deployed to places like Da Nang AB and Phan Rang AB in South Vietnam and Takhli RTAFB and Korat RTAFB in Thailand. Initially, TAC began deploying squadrons of F-100 Super Sabre, RF-101 Voodoo and F-105 Thunderchief aircraft to these overseas installations under the cognizance of PACAF. As the American effort in Southeast Asia increased, TAC used a process of deploying squadrons to PACAF-operated bases in South Vietnam and Thailand, with the squadrons being attached temporarily on rotational deployments or being permanently reassigned to the PACAF wing.
