On 17 November 1947, the 92d Bombardment Wing, Very Heavy was organized at Spokane Army Air Field, Washington as part of the United States Air Force's wing base reorganization, in which combat groups and all supporting units on a base were assigned to a single wing. The 92d Bombardment Group, flying Boeing B-29 Superfortresses became its operational component. It served as a double-sized B-29 wing until April 1950, and again from May 1950 to April 1951, although one bomb group was generally deployed overseas for training or combat in Korea. It also supervised the 454th Bombardment Group, a Reserve corollary bomb group from June 1949 until February 1951, when the 454th was called to active duty for the Korean War.
