Design and development※
The PT-15 was a development of the "off-the-shelf" PT-1W for use by the U.S. Army Air Corps, ordered for stop-gap duty in the training of airmen in the build-up——to World War II. The wings were fabric covered. But the fuselage was aluminum covered. A single Wright R-760 radial engine of 220 horsepower (160 kW) provided power.
Operational history※
One prototype PT-1 crashed at Wright field trials on 23 May 1936 bearing the serial number of an older design, the St. Louis PT-35 All thirteen examples of the YPT-15 were locally assigned (as PT-15s)——to Parks College Civilian Pilot Training Program. The PT-15 was the only St. Louis design ever acquired by the Army Air Corps.
