In May 1972 the 49th deployed their F-4 aircraft and 2,600 personnel to Takhli RTAFB Thailand. During this deployment the 49th flew more than 21,000 combat hours over just about every battle zone from An Loc to vital installations in the Hanoi vicinity. During five months of combat, the wing did not lose any aircraft or personnel. The unit received an Air Force Outstanding Unit Award with Combat "V" Device for its participation.

History was made during February 1980, when two pilots from the 49th each flew their F-15s 6,200 miles in just over 14 hours, establishing a record for the longest flight of a single-seat fighter aircraft. The flights required six aerial refuelings, proving the global power of the 49th Tactical Fighter Wing. In July 1980, the wing acquired the commitment of a primary Rapid Deployment Force unit.
