The 39th BW trained to maintain combat readiness for strategic bombardment on global scale, maintaining airborne alert, ground alert, and participated in numerous exercises. On 25 June 1965 The growing United States commitment to the Vietnam War meant funds were also needed to cover the costs of combat operations in Indochina and the 39th Bombardment Wing was inactivated on 25 June 1965. The wing's 62d BS was reassigned to the 2d Bombardment Wing at Barksdale AFB, Louisiana to support SAC Arc Light combat operations over Southeast Asia but its other components were discontinued. SAC's place at Eglin was taken by Tactical Air Command, which organized the 33d Tactical Fighter Wing, which took over the SAC facilities at the base.
