The aircraft was used at the station from March 1941 until late 1942. There were 100 aircraft assigned to NAS Jacksonville and they were used for primary flight training. Being under-powered, they were known as the "Flying Washing Machines" by the early students." |

| Ryan S-T-A-1 XPT-16 (39-717 c/n 306) US Army Air Corps. The pictured aircraft was subsequently re-engined with an 125 hp Kinner B-54 five-cylinder radial (military designation R-440), and redesignated to XPT-16A. On July 31, 1942, the aircraft was deregulated to CL-26 status, becoming a maintenance trainer. It was scrapped on March 27, 1945. |

| Ryan S-T-A PT-20 US Army Air Corps. In 1940 an order was placed for forty of a basically similar model designated PT-20. This was the same aircraft and engine as the YPT-16 with the principal outward difference being a larger cockpit with external longerons, which allowed more room for parachutes. |
 |
| Ryan S-T-3KR NR-1 Recruit US Navy. As the war tempo grew, the Army and Navy standardized on the S-T-3KR or PT-22 Recruit as an even more powerful trainer. Equipped with a 160 hp Kinner R-540-1 engine, and delivered without wheel spats or fairings over the gear struts, the PT-22 was otherwise identical to the PT-21. Navy designation for the PT-22 was NR-1 and 100 were produced. |
 |
| Ryan S-T-4 YPT-25 US Army Air Forces. In 1942 production ended on the S-T series. At this time Ryan was given a contract to develop a version of the trainer using non-strategic materials. The five YPT-25s built, s/n 42-8703 to 42-8707, c/n 1775 to 1779, were almost entirely of plastic-bonded wood as a result of a request to convert the all-metal PT-22 trainer to non-strategic materials. The prevailing aluminum shortage did not materialize and production was not undertaken. |
