History On 6 February 1922, a detachment of 20 enlisted men from Luke Field, proceeded to Schofield Barracks, under Lieutenant William T.

Two canvas hangars were erected and the field cleared of weeds, guava and algaroba trees. Thus Wheeler Field got its modest start. It was named Wheeler Field on 11 November 1922 in honor of Major Sheldon H. Wheeler, former commander of Luke Field on Ford Island, killed in the crash of DH-4B, AAS Ser. No. 63525 on 13 July 1921. In June 1923, 13 months after the designation of the new flying field, shop hangars, airplane hangars, and oil storage tanks were erected. In 1927, one of the wooden shop hangars was remodeled to provide space for a barracks and a mess hall incident to the formation of a pursuit group. It was not until 1930 that any permanent construction was started. Many different units were originally stationed at Wheeler Field.

In October 1922, the photo section and intelligence units were returned to Luke Field. The following May, the 17th Composite Group was organized at Wheeler.
