In 1937 the Allison V-1710 became the first American engine to qualify at 1,000 horsepower for the new 150-hour military type test. The V-1710-C was also the first in the “long nose” series that provided a basis for later improved and higher powered versions. Allison designers created the long nose by extending the propeller shaft about 30 centimeters (12 inches) to maximize streamlining.
The Allison V-1710 powered most U.S. Army fighters in World War II, including the Lockheed P-38, Bell P-39 and P-63, Curtiss P-40, and early North American P-51s. The V-1710-C15 (military designation V-1710-33) powered the Curtiss P-40, P-40A, B, and C pursuit aircraft.
