In October 1942, the group moved to Langley Field and operated with AAF Antisubmarine Command, using such planes as B-17 Flying Fortress, B-18 Bolo, B-24 Liberator and A-20 Havoc to fly Anti-submarine warfarepatrols along the east coast.[1] The 304th also trained crews for antisubmarine patrol duty overseas.[1] In early November, the 361st squadron moved to St Eval, England and began antisubmarine operations for Eighth Air Force. In late November, three of the group's squadrons were redesignated as Antisubmarine Squadrons. In December the group was inactivated and its squadrons transferred to the 25th Antisubmarine Wing.[2][3][4]
