Pratt & Whitney Wasp series

Template:Short description Template:Infobox aero engine The Pratt & Whitney Wasp was the civilian name of a family of air-cooled, radial piston engines developed in the 1920s, 1930s, and 1940s.Template:Sfn

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.Template:SfnTemplate:Sfn The name "Wasp" was suggested for the first model by Rentschler's wife, Faye.Template:SfnTemplate:Sfn
