Its last assignment was with the 305th Bombardment Wing at Bunker Hill Air Force Base, Indiana, where it was inactivated on 1 January 1970.

Following V-E Day, the squadron moved to Germany, where it formed part of the occupation forces until inactivating in December 1946.

The air echelon received additional training at Hancock Field, New York, before taking the North Atlantic ferrying route to Prestwick in September and October.

Between 20 and 25 February 1944, it took part in Big Week, the intensive campaign by Eighth Air Force against the German aircraft manufacturing industry.

[4][7] On the first day of Big Week, the B-17 flown by Lt William R. Lawley was attacked head on by German fighters as it turned away from the target.

Because of the fire and the inability of the plane to release it bombs, Lt Lawley ordered the crew to bail out because of the danger of an explosion.

[8] Less than two months later, on 11 April 1944, a squadron bomber flown by Lt Edward S. Michael was hit by cannon shells, causing the aircraft to enter a spin.

Recovering from the spin, the pilots found that part of the plane's incendiary bomb load had caught fire.

Although loss of blood rendered him periodically unconscious, Lt Michael was able to make a successful crash landing.

Prior to Operation Overlord, the invasion of Normandy, it helped neutralize enemy forces with attacks on airfields, V-1 flying bomb and V-2 rocket launch facilities and repair shops.

In July 1944 it attacked enemy positions in advance of ground forces in Operation Cobra, the breakout at Saint Lo.

[4] Following V-E Day, the squadron moved to Sint-Truiden Airfield in Belgium, from which it conducted photographic mapping flights over Europe and North Africa which came under the name Project Casey Jones.

By the first week of November, 84 B-58s were standing nuclear alert, and as SAC redeployed its Boeing KC-135 Stratotankers, 20 of these were "first cycle" sorties.

[10][11] In December 1965, Robert S. McNamara, Secretary of Defense announced a phaseout program that would further reduce SAC’s bomber force.
