The 377th Bombardment Group was activated in October 1942 as the headquarters for antisubmarine units operating along the Atlantic coast of the United States. Shortly after it was organized, Army Air Forces Antisubmarine Command reorganized its squadrons in the area to reassign them directly to the 25th Antisubmarine Wing and the group was inactivated. In 1985, the group was redesignated the 357th Tactical Missile Group.
