The Pratt & Whitney R-1340 Wasp is an aircraft engine of the reciprocating type that was widely used in American aircraft from the 1920s onward. It was the Pratt & Whitney aircraft company's first engine, and the first of the famed Wasp series. It was a single-row, nine-cylinder, air-cooled, radial design, and displaced 1,344 cubic inches (22 L); bore and stroke were both 5.75 in (146 mm). A total of 34,966 engines were produced.<ref>Pratt&Whitney R-1340 page Retrieved: 25 October 2008</ref>
As well as numerous types of fixed-wing aircraft, it was used to power helicopters, the Agusta-Bell AB.102 and the Sikorsky H-19, and a class of airship, the K-class blimp.
In 2016, it received designation as a Historic Engineering Landmark from the American Society of Mechanical Engineers.<ref>"Pratt’s first engine gets historic designation" from Hartford Business Journal, published February 1st Retrieved: 7 April 2016</ref>
