The Stearman model 75, widely known as the Stearman, Boeing Stearman (Stearman became a subsidiary of Boeing in 1934) or Kaydet was a biplane built in the United States during the 1930s as a military trainer aircraft. It served as the basic trainer for the USAAF and USN throughout World War II and after the conflict was over, thousands of surplus aircraft were sold on the civil market. In the immediate post-war years they became popular as crop dusters and as sports planes.
The Kaydet was of rugged construction, and conventional biplane design with large, fixed tailwheel undercarriage, and accommodation for the student and instructor in open cockpits in tandem. The radial engine was uncowled.
