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.[1] To carry out this mission,Fourth Air Force organized regional air defense wings in August 1942.[2][3] TheLos Angeles Air Defense Wing was organized to provide air defense for theLos Angeles area and train fighter groups and pilots.[4]
TheArmy Air Forces later found that standard military units like thewing, whose manning was based on relatively inflexibletables of organization were not well adapted to the training mission, even more so to the replacement mission. Accordingly, theArmy Air Forces adopted a more functional system in which each base was organized into a separate numbered unit, with similar flexible units established for headquarters.[5]
In this reorganization, the wing's headquarters squadron was replaced by the 410th AAF Base Unit (Fighter Wing) on 1 April 1944. The wing itself was disbanded on 7 July 1944,[4] and the 410th was redescribed as the 410th AAF Base Unit (Air Defense Region). In 1946, it became the 410th AAF Base Unit (Los Angeles Control Group), and was discontinued on 1 January 1947.
^When theUnited States Air Force became a separate service in September 1947, all former Army Air Forces units, including disbanded units were transferred to its control.
^However, Robertson indicates the group was assigned directly to IV Fighter Command until March 1944, then directly to Fourth Air Force.Robertson, Patsy (May 2012)."Factsheet 412 Test Wing (AFMC)". Air Force Historical Research Agency. Retrieved16 January 2022.
