Founded 1928 at St Louis, Missouri, as Mahoney-Ryan Aircraft Corporation, deriving from Ryan Airlines, which began operations on U.S. West Coast in 1922, and in 1926 began manufacture of Ryan M-1 mailplane from which Charles Lindbergh's transatlantic Ryan NYP Spirit of St Louis was developed in 1927. Commercial version of the latter, Ryan Brougham, was built in quantity. Ryan merged with Detroit Aircraft Corporation in 1929, but DAC did not survive the slump in 1930-1931. T. Claude Ryan formed Ryan Aeronautical Company in 1933-1934 and produced the S-T training monoplane, forerunner of a series of successful

Ryan trainers. The YO-51 Dragonfly of 1940 was observation monoplane built for the USAAC. A new fighter for the U.S. Navy in 1943 reflected a "belt and braces" outlook on the new gas turbine engine, having a mixed powerplant comprising a conventional piston engine and rear-fuselage jet. Known as the FR-1 Fireball, it was too late to see operational service in Second World War. Acquired design and manufacturing rights of Navion four-seat all-metal monoplane from North American Aviation in 1947 and put it into quantity production. Ryan developed to a mid-1950s USAF contract the X-13 Vertijet, a delta-wing vertical-take-off jet with Rolls-Royce Avon engine. A flex-wing research aircraft was built in 1961, and the XV-5A lift-fan research aircraft followed in 1964. Development of the "fan-in-wing" VTOL principle continued with two prototype aircraft, later restyled XV-5B.
