History Ryan Aeronautical Company
The ST-A was further developed as the ST-A Special,
with a super-charged 150HP Menasco C4-S engine of increased power.
Five STs were built, each powered with a 95HP Menasco B4 engine [6] before the follow-on ST-A (A for Aerobatic) was developed with a more powerful 125HP Menasco C4 engine. A single ST-B was produced, this being an ST-A with only one seat and an extra fuel tank where the front cockpit normally was; this aircraft was subsequently converted back to ST-A standard. The ST-A was further developed as the ST-A Special, with a super-charged 150HP Menasco C4-S engine of increased power.
T. Claude Ryan was the founder of the Ryan Aeronautical Company, the second incarnation of a company with this name, and the fourth company with which he had been involved to bear his name (the first, Ryan Airlines, was the manufacturer of the Ryan NYP, more famously known as the Spirit of St. Louis). He began the development of the ST (for "Sport Trainer", and also known as S-T), the first design of the company, in 1933

American aviation in the early 1930’s was heavily influenced by the National Air Races. The popular Greve Race ((550 cubic inch maximum) was dominated by aircraft powered with the air cooled Menasco four cylinder Pirate engines. These inline engines permitted superior streamlining, higher speeds and very sleek designs.
