Type	Radial engine
National origin	United States
Manufacturer	Pratt & Whitney

The Pratt & Whitney Wasp was the civilian name of a family of air-cooled radial piston engines developed in the 1920s, 1930s and 1940s.^[1]

The Pratt & Whitney Aircraft Company (P&W) was founded in 1925 by Frederick B. Rentschler, who had previously been the President of Wright Aeronautical. He brought with him some of Wright's best designers and the new team quickly came up with their first design, the R-1340 Wasp.^[1]^[2] The name "Wasp" was suggested for the first model by Rentschler's wife, Faye.^[3]^[4]
