Prior to their acquisition of the Ryan PT-20 the United States Army Air Corps only used biplanes as primary training aircraft.

In 1939 the U.S. Army was seeking a new primary trainer. When they tested the Ryan STA it was found to meet all of their requirements. As a result Ryan received an initial order for thirty aircraft. Eventually over 1,000 were delivered to the U.S.A.A.C.

Eventually the in-line aircraft engine was replaced with a more powerful, distinctive sounding five cylinder radial. The fuselage was made more round and strengthened to accommodate the new engine.

Other changes involved removal of the landing gear strut covers and wheel covers which resulted in an exposed landing gear. The main gear was strengthened and its track made wider. All control surfaces received aerodynamic upgrades for improved handling.

Another variant had interchangeable landing gear and floats. The cockpit was widened. Some aircraft had provisions to be fitted with machine guns.

Ryan PT-20 aircraft and their variants were exported throughout the world. During World War II, in addition to being used as primary trainers, a number of the aircraft saw action doing artillery spotting and reconnaissance.  Aircraft equipped with machine guns were used for light attack by the Chinese.

Some 1,273 Ryan PT-20 aircraft of all types were produced. Today a number continue to fly in the United States, Great Britain, and Australia.
