The Pratt & Whitney R-2800 Double Wasp was a twin-row, 18-cylinder, air-cooled radial aircraft engine with a displacement of 2,800 in³. That works out to 46 Liters for the performance race car guys! The Double Wasp is part of the long-lived Wasp family.
The R-2800 is still considered one of the premier radial piston engines ever designed and is notable for its widespread use in many important American aircraft during and after World War II. During the war years, Pratt & Whitney continued to develop new ideas to upgrade this already powerful workhorse, most notably water injection for takeoff in cargo and passenger planes and to give emergency power in combat.
Stratford’s own, the mighty F4U Corsair used the R-2800 In all of its major forms, from the development prototype to the CB series in the 1950’s.
