The Ryan Aeronautical Company was founded by T. Claude Ryan in San Diego, California, in 1934. It became part of Teledyne in 1969, and of Northrop Grumman when the latter company purchased Ryan in 1999. Ryan built several historically and technically significant aircraft, including four innovative V/STOL designs, but its most successful production aircraft was the Ryan Firebee line of unmanned drones used as target drones and unmanned air vehicles.<ref>Template:Cite news</ref>
HistoryEdit
Early historyEdit
In 1922, T.C. Ryan founded a flying service in San Diego that would lead to several aviation ventures bearing the Ryan name, including Ryan Airline Company founded in 1925.<ref>Template:Cite journal</ref>
T.C. Ryan, whose previous companies were best known for building Charles Lindbergh's transatlantic Spirit of St. Louis, actually had no part in building the famous aircraft.<ref>Spirit and Creator: The Mysterious Man Behind Lindbergh's Flight to Paris by Nova Hall</ref><ref>The Untold Story of the Spirit of St. Louis by Ev Cassagneres</ref><ref name="charleslindbergh">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name="charleslindbergh2">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name="charleslindbergh3">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name="charleslindbergh4">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Ryan had been owner or partner in several previous companies, one of which also bore the name Ryan Aeronautical. The Spirit of St. Louis was not built by the final Ryan Aeronautical entity.<ref>Template:Cite news</ref>
The new company's first aircraft was the S-T Sport Trainer,<ref name="ev">Template:Cite book</ref> a low-wing tandem-seat monoplane with a Template:Cvt Menasco B-4 Pirate straight-4 engine. Five were built before production switched to the Ryan ST-A Aerobatic with a more powerful Template:Cvt Menasco C-4 in 1935. This aircraft now had enough power for aerobatic display, and it won the 1937 International Aerobatic Championships. A further improved ST-A Special was built in 1936, with a supercharged Template:Cvt Menasco C-4S.
In 1937 and 1938, a second civilian aircraft model was introduced, the S-C Sport Coupe, or SC-W with a Template:Cvt Warner Super Scarab radial engine. The SC-W was a larger three-seater aircraft with a sliding canopy and side-by-side front seating. The prototype SC-M was originally powered by a Menasco C-4 inline engine, however testing revealed that more power was needed. Thirteen examples of the SC-W were built, although the last one was assembled from surplus parts decades after the initial production run was finished.
USAAC trainersEdit
Interest from the United States Army Air Corps followed. The Menasco engines proved unreliable, and instead Kinner radial engines were fitted. Aircraft were produced as the PT-16 (15 built); PT-20 (30 built); PT-21 (100 USAAF, 100 USN); and finally as the definitive PT-22 Recruit (1,048 built) ordered in 1941 as pilot training began its rapid expansion.
Ryan also pioneered STOL techniques in its YO-51 Dragonfly liaison and observation craft, but only three were built.<ref name="ec">Template:Cite book</ref>
PostwarEdit
In the immediate postwar years, Ryan bought the rights to the Navion light aircraft from North American Aviation, selling it to both military and civilian customers.<ref name=ec/>Template:Rp
Ryan became involved in the missile and unmanned aircraft fields, developing the Ryan Firebee unmanned target drone, the Ryan Firebird (the first American air-to-air missile) among others, as well as a number of experimental and research aircraft.
Ryan acquired a 50% stake in Continental Motors Corporation, the aircraft-engine builder, in 1965.<ref>Leyes, Richard A., and William A. Fleming, The History of North American Small Gas Turbine Aircraft Engines, Smithsonian Institution, Washington, DC, 1999: p.143 Template:ISBN</ref>
In the 1950s, Ryan was a pioneer in jet vertical flight with the X-13 Vertijet, a tail-sitting jet with a delta wing which was not used in production designs. In the early 1960s, Ryan built the XV-5 Vertifan for the U.S. Army, which used wing- and nose-mounted lift vanes for V/STOL vertical flight. Other Ryan V/STOL designs included the VZ-3 Vertiplane.<ref name=ec/>Template:Rp
Ryan developed the highly accurate radar system used on the Apollo Lunar Module.<ref name=ec/>Template:Rp
In 1968, the company was acquired by Teledyne for $128 million and a year later became a wholly owned subsidiary of that company as Teledyne Ryan Aeronautical Company.<ref name=ec/>Template:Rp
Northrop Grumman purchased Teledyne Ryan in 1999, with the products continuing to form the core of that firm's unmanned aerial vehicle efforts.
