[2][3] The squadrons were all initially formed at Salt Lake City Army Air Base, and did not join group headquarters at Topeka until late August.

In February 1943 it moved to Dalhart Army Air Field, Texas, and shifted its mission to become a Replacement Training Unit (RTU).

[2][4] However, the Army Air Forces found that standard military units like the 333d, based on relatively inflexible tables of organization, were not proving well adapted to the training mission.

[5] As a result, the group was inactivated and training activities at Dalhart were assumed by the 232d (bomber) and 268th (fighter) AAF Base Units.

It arrived in Okinawa, but the end of the war with the defeat of Japan led to a drawdown of Eighth Air Force and the group never engaged in combat.

[11] The wing managed the reduction of United States forces at Pleiku until March 1970, when it was inactivated and transferred its remaining equipment and personnel to the 6254th Air Base Squadron.
