The 18th Composite Wing served as part of the defense force for the Hawaiian Islands from 1 May 1931 – 29 January 1942. It inactivated after suffering disastrous losses in the Japanese attack on Pearl Harbor (7 December 1941).

From June 1942 – April 1944, it operated as the 18th Replacement Wing, processing personnel entering Second Air Force.

Redesignated as the 18th Air Division on 1 July 1959, it assured that assigned wings were organized, manned, trained, and equipped to conduct long-range bombardment operations using either nuclear or conventional weapons.
