History

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).^[1]

From June 1942 until 1944, it operated as the 18th Replacement Wing, processing personnel entering Second Air Force.^[1]

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

The division was redesignated as 18 Strategic Aerospace Division on 15 February 1962, and also developed and maintained a strategic missile operational capability. Between 1965 and 1968, subordinate units of the 18th loaned aircraft and aircrews to SAC organizations for combat during the Vietnam War.^[1]

The division was inactivated on 2 July 1968 due to budget constraints.^[1]
