  The San Diego Fighter Wing is a disbanded United States Air Force unit. The wing provided air defense of southern California and trained fighter units and pilots. It was stationed at San Diego, California, where it was disbanded on 7 June 1944.
  
  ## History
  
  Along the Pacific coast, Western Defense Command established a "vital air defense zone", extending from the coast approximately 150 miles (240 km) inland and 200 miles (320 km) to sea. To carry out this mission, Fourth Air Force organized regional air defense wings in August 1942. Only one squadron of Army Air Forces fighters were attached to the wing, with most tactical elements drawn from the Navy.
