The group changed aircraft frequently during its service between wars, as new types were developed and older models became outdated. It began its service flying Curtiss JNS, SE-5, and Fokker D.VII fighters left over from the First World War. From 1922 to 1925 it operated primarily MB-3A fighters. In 1925 it acquired Curtiss PW-8s for use by the 17th Pursuit Squadron, in 1926 Curtiss P-1 Hawks (a derivative of the PW-8), and in 1929 Boeing P-12s. Throughout this period each squadron often operated a different fighter type from the others.
