History

The 12th Bombardment Group was a medium bomber group during WWII that flew B-25 Mitchells prior to converting (partially) over to the A-26 Invader. The unit is still active today as the 12th Operations Group and is based at Randolph AFB.

The Group was officially formed on 15 Jan 1941 at McChord Field, Washington, as part of the US buildup of forces. They initially flew coastal anti-submarine patrol routes, which increased in activity between 7 Dec 1941 and the unit's deployment to North Africa in Oct 1942.

In October 1942, the 12th Bomb Group arrived in Egypt and trained with the RAF and South African Air Force. They helped support the British 8th Army and fended off attacks from the German Afrika Corps.

By June 1943 the group had moved to Hergla Airfield, Tunisia and began striking at targets in Italy. In August the group moved to Sicily and continued their assault until Feb 1944.

In March 1944 the unit was transferred to India and began operations in the CBI Theater. The unit was based out of Tezgaon Airfield, Pandaveswar Airfield, Fenny Airfield, and then back to Pandaveswar Airfield. Karachi Airport was the final airbase they were stationed at in India.

At the conclusion of World War II the unit was transferred to Fort Lawton, Washington in Jan 1946 for inactivation.

In May 1947 the Unit was reactivated at Langley Field and flew A-26 Invaders until September 1948 when they were again inactivated.
