The Curtiss D-12, sometimes identified with the military designation Curtiss V-1150, was an aircraft engine of 18.8 liter displacement. It was a water-cooled V12, producing 443 hp (330 kW) and weighing 693 lb (314 kg). It was designed by Arthur Nutt in 1921 and used in the Curtiss CR-3 for the 1923 Schneider Trophy race. Fairey Aviation of England imported 50 Curtiss-built examples in 1926, renaming them the Fairey Felix.[1][2]

The D-12 was one of the first truly successful aluminum cast-block engines and was extremely influential in the interwar period. Numerous engines trace their design to the D-12, among them the Packard 1A-1500, Rolls-Royce Kestrel and Junkers Jumo 210.
