After the attack on Pearl Harbor, the group was ordered to search for German U-boats off the southeast coast. Although the Navy was responsible for long range patrolling, it lacked the aircraft to perform the mission and the Army Air Forces (AAF) performed the mission, even though its crews lacked proper training.[7] As antisubmarine warfare assets were realigned to meet the growing threat in the North Atlantic, the 13th Group moved to Westover Field, Massachusetts in January 1942.[2] The following month, the 3d Reconnaissance Squadron was assigned to the group, and, in April, became the 393d Bombardment Squadron.[6]
The group was converted to provisional status, redesignated the 13th Air Expeditionary Group and assigned to Pacific Air Forces to activate or inactivate as needed. It has been used primarily to control operations or exercises for Thirteenth Air Force. This has included acting as the air component of Joint Task Force-Support Forces Antarctica. The group commander is dual hatted as the deputy commander, JTF-SFA.[1][10]
