The 25th Antisubmarine Wing is an inactive United States Air Force unit. Its last assignment was with the Army Air Forces Antisubmarine Command, based in New York City, New York. It was the principal United States Army Air Forces Unit conducting anti-submarine warfare off the Atlantic Coast of the United States and Canada until it was disbanded on 15 October 1943. In 1985 the wing was reconstituted and redesignated the 525th Combat Crew Training Group, but has never been active with that designation.
