Pratt & Whitney R-2800

The Pratt & Whitney R-2800 Double Wasp was an aircraft engine, and part of the long-lived Wasp family. It was a two-row, 18-cylinder, air-cooled radial design. Displacement was 2,804 cubic inches (46 liters); bore and stroke were 5.75" and 6".

The R-2800 is considered one of the premier radial piston engines ever designed. It became legendary when used in several aircraft during World War II, notably the F4U Corsair, P47 Thunderbolt, and the Grumman F6F Hellcat. During the war years, Pratt-Whitney were always coming up with new ideas to upgrade this already powerful workhorse, most notably water injection to give emergency power in combat. After World War II, the engine was used in the Korean War, and surplus World War II aircraft powered with the Double-Wasp served with other countries well past the Korean War, some being retired as late as the latter part of the 1960s when the aircraft were replaced. Today, more than 50 years after the first Double Wasp was built, it is still used in a few aircraft in air shows.
