The 4702nd Defense Wing is a discontinued wing of the United States Air Force, last assigned to the 25th Air Division at Geiger Field, Washington. It was established in 1952 at Hamilton AFB, California in a general reorganization of Air Defense Command (ADC), which replaced wings responsible for a base with wings responsible for a geographical area. It moved twice in the first few months it was active and as a result became non operational until early 1953. It then assumed control of several Fighter Interceptor and Radar squadrons in the Pacific Northwest, some of which were Air National Guard squadrons mobilized for the Korean War. It was discontinued in the fall of 1954 and its units transferred to the new 9th Air Division.

The 25th Air Division is an inactive United States Air Force intermediate echelon command and control organization. It was last assigned to First Air Force, Tactical Air Command (ADTAC). It was inactivated on 30 September 1990 at McChord Air Force Base, Washington.
