# 463d Bombardment Squadron

The 463d Bombardment Squadron is an inactive United States Air Force unit. Its last assignment was with 346th Bombardment Group at Kadena Airfield, Okinawa, where it was inactivated on 30 June 1946. From 1942 the squadron served as a replacement training unit for heavy bomber aircrews. It was inactivated in the spring of 1944 in a general reorganization of Army Air Forces training units. The squadron was activated again in 1944 as a Boeing B-29 Superfortress unit. Although it deployed to the Pacific, it arrived too late to see combat service.

## History
### Heavy bomber replacement training

The 463d Bombardment Squadron was first activated in July 1942 at Salt Lake City Army Air Base, Utah as one of the four original squadrons of the 331st Bombardment Group. In September it moved to Casper Army Air Field, where it became a Boeing B-17 Flying Fortress Replacement Training Unit until 1943, when it converted to the Consolidated B-24 Liberator. Replacement training units were oversized units which trained aircrews prior to their deployment to combat theaters.
However, the Army Air Forces found that standard military units, based on relatively inflexible tables of organization, were not proving to be well adapted to the training mission, particularly to replacement training. Accordingly, it adopted a more functional system in which each base was organized into a separate numbered unit, while the groups and squadrons acting as replacement training units were disbanded or inactivated. This resulted in the 463d, along with other units at Casper, being inactivated in the spring of 1944 and being replaced by the 211th AAF Base Unit (Combat Crew Training Station, Heavy), which assumed the 331st Group's mission, personnel, and equipment.

### Very heavy bomber operations

In August 1944, the squadron was reactivated as a Boeing B-29 Superfortress unit at Dalhart Army Air Field, Texas and assigned to the 346th Bombardment Group. In December it moved to Pratt Army Air Field, Kansas, where it began training with B-29s, along with some B-17s until B-29s became available. In June 1945, it began moving to Okinawa to become part of Eighth Air Force. , which was organizing on Okinawa as a second B-29 force for the strategic bombing campaign against Japan. The squadron arrived at its combat station, Kadena Airfield, Okinawa two days before V-J Day. Although the war ended before the squadron could begin operations, a few of its crews formed part of its forward echelon and flew missions with B-29 units of Twentieth Air Force.
The squadron flew several show of force missions from Okinawa over Japan following VJ Day. It also evacuated prisoners of war from camps in Japan to the Philippines. The squadron was inactivated on Okinawa in June 1946.
