Wright T-3

Developed by Wright Aeronautical, on the lines of the Wright-Hisso engines produced during the First World War, using monobloc cylinder blocks and gear driven overhead camshafts. The T-1 of 1921 had a power output of 500 hp (373 kW), and went into production as the T-2 in 1922 with an increase in power to 525 hp (391 kW).

The T-3 was the third in the line of 'T' (Tornado) series engines. The T-3 and T-3A appeared from 1923 producing 575 hp (429 kW) with the final development, the T-4, producing 675 hp (503 kW) by December of that year. Wright attempted to build a racing version of the T rated at 700 hp (522 kW) to rival the Curtiss D-12, but this was not pursued.

The Wright T-3 Tornado, also given the USAF designation Wright V-1950.
