It was last assigned to the 485th Tactical Missile Wing at Florennes Air Base, Belgium, where it was inactivated on 30 September 1989 with the implementation of the Intermediate-Range Nuclear Forces Treaty.

Shortly after the attack on Pearl Harbor, the squadron deployed to the Southwest Pacific Theater, participating in combat until V-J Day, moving forward from Australia to Okinawa.

The squadron was again activated in France in 1953, when it replaced an Air National Guard unit that had been mobilized for the Korean War and was being returned to state control.

The air echelon remained at Jackson and continued training, converting to North American B-25 Mitchells, until the summer of 1942, when it departed for the Southwest Pacific Theater.

[3] The air echelon arrived at its first combat station, Breddan Aerodrome, Queensland, Australia in early August 1942.

From this base, it bombed airfields, ground installations, harbors and shipping in the southern Philippines to support the invasion of Leyte.

It was awarded a third DUC for strikes on a large enemy convoy at Ormoc Bay on 10 November that prevented the landing of supplies and reinforcements, that were critical to the outcome of the Battle of Leyte.

In July 1945, the squadron moved to Okinawa, attacking industrial targets, rail transportation and shipping in southern Japan until V-J Day.

Over the next two years, the squadron completed an upgrade of its Invader force to planes equipped for night intruder missions.

[7] In January 1955, the squadron's pilots began flying missions in jet Lockheed T-33 T-Birds to prepare them for conversion to Martin B-57B Canberras.

It would not be until the end of the year before the first B-57Cs, equipped with dual controls were on hand, so for some squadron pilots, their first solo in the Canberra was also their first flight in the bomber.

To maintain efficiency in its operational mission, the squadron deployed to Wheelus Air Base, Libya for gunnery and bombing practice.

[citation needed] The Air Force's pilot requirements continued to drop, and the squadron ended operations in November 1975.

The squadron was inactivated on 1 December 1975 along with the 38th Wing[18][19] when Moody became a tactical tighter base after the Vietnam War ended.
