The unit was assigned to Fifth Air Force in the Philippines in 1944 for operations with North American P-51 Mustangs, Douglas C-47 Skytrains, and Stinson L-5 Sentinels.

It attacked Japanese airfields and installations in the Philippines, supported ground forces on Luzon, and provided escort for missions to Formosa and the China coast.

In addition, the group transported personnel, dropped supplies to ground troops and guerrilla forces, evacuated casualties from front-line strips, adjusted artillery fire, and flew courier and mail routes.

The flying personnel of the 3rd and 4th Fighter Squadrons, as well as some enlisted members of their engineering sections, were air-transported to Nadzab, New Guinea, where they received the group's new P-51 aircraft.

The air echelon of the 318th Troop Carrier Squadron flew their C-47s across the Pacific, arriving at Nadzab, New Guinea, in late October 1944.

The liaison squadrons received their L-5s in late January 1945, and thereafter evacuated wounded from advanced points, flew courier, search and rescue, and reconnaissance missions, spotted for signal aircraft warning battalions, and dropped supplies to allied and guerrilla forces.

In April 1945, the group, less the liaison squadrons, moved from Mandaldan, in Lingayen Gulf, to Laoag, in northwest Luzon, in recently captured territory 150 miles behind enemy lines.

Moved to Thailand in increments beginning mid-September 1967 and began day and night unarmed reconnaissance missions over Southeast Asia on 25 November 1967.

A wing detachment at Nakhon Phanom Royal Thai Air Force Base, Thailand, performed combat evaluation of YQU-22A aircraft and associated equipment, December 1968 – August 1969.

From July to early September 1970 the wing provided combat evaluation of the QU-22B aircraft and on 1 October 1970 the QU-22Bs were placed in full operation, reducing the need for EC-121s.

In 2011, the unit supported Operation TOMODACHI, the relief effort from the great East Japan earthquake and tsunami of 2011.
