Boeing-Stearman Model 75 Biplane History
The Boeing-Stearman Model 75 is one of the most recognisable biplanes of all time. Originally designed by Lloyd Stearman, of Stearman Aircraft, as the Stearman Model 75, it was a relatively sophisticated and expensive aircraft. When Boeing acquired Stearman Aircraft in 1934, making it a subsidiary of Boeing, they effectively gained the rights to the Boeing-Stearman Model 75 trainer and renamed it the Boeing Kaydet.

The Boeing Kaydet aircraft was first introduced as a tandem biplane military trainer in 1934. It was widely used by the USAAF, USN and the RCAF with a total of over 10,000 aircraft being produced.

Boeing-Stearman Model 75 During WW2
The Boeing-Stearman Model 75 trainers used during WW2 by the USAAF (United States Army Air Force) were designated PT-13, PT-17 and PT-18. The USN (United States Navy) designated it's Boeing Kaydet biplanes as either NS, N2S-1, N2S-2, N2S-3, N2S-4, N2S-5. The designation variants primarily designate the engine model fitted.

Boeing-Stearman Model 75 Post WW2
After WW2 thousands of surplus Boeing Kaydet trainers found their way on to the civilian market where they made excellent crop dusters, personal aerobatic aircraft and air taxi transports.

Various scale models, model kits and plans of this aircraft have been available in the market place.
