Continental XI-1430

Continental XI-1430

The Continental XI-1430 Hyper engine (often identified as the IV-1430) was a liquid-cooled aircraft engine developed in the United States by a partnership between the US Army Air Corps and Continental Motors. It was the "official" result of the USAAC's hyper engine efforts that started in 1932, but never entered widespread production as it was not better than other available engines when it finally matured. In 1939, the I-1430-3 was designated as the engine to power the Curtiss XP-55, an extremely radical (for the time) pusher-engine fighter design that would not reach production.
