Ryan ST/ PT-22 Recruit

Ryan re-entered aircraft manufacturing in 1933 with braced low-wing monoplane tandem open-cockpit trainer powered by a Menasco inline engine...the S-T (Sport-Trainer).  The U.S. Army purchased this aircraft for the primary training role as the PT-16 in 1939.  A few structural changes resulted in the PT-20.

In 1941, Ryan developed the ST-3KR by changing the engine to a Kinner radial.  The U.S. Army purchased this trainer as the PT-21.

A more powerful Kinner radial and the deletion of the landing gear fairings resulted in the most common version (over 1,000 built), the PT-22 Recruit.  The Navy purchased this aircraft as the NR-1.
