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 ...
R-2600-14 - 1,700 hp (1,268 kW)- One of the engines which powered Grumman's prototype F6Fs, the XF6F-1 (the two-stage supercharged R-2600-10 was also tested in the XF6F-1). Grumman was not happy with the performance, which led to the 2,000 hp Pratt & Whitney R-2800 engine replacing the R-2600 on F6F production models.
The Pratt & Whitney R-4360 Wasp Major is an American 28-cylinder four-row radial piston aircraft engine designed and built during World War II.At 4,362.5 cu in (71.5 L), it is the largest-displacement aviation piston engine to be mass-produced in the United States, and at 4,300 hp (3,200 kW) the most powerful.
The Pratt & Whitney R-2800 Double Wasp is an American twin-row, 18-cylinder, air-cooled radial aircraft engine with a displacement of 2,800 cu in (46 L), and is part of the long-lived Wasp family of engines. The R-2800 saw widespread use in many important American aircraft during and after World War II.
The Pratt & Whitney R-1830 Twin Wasp is an American air-cooled radial aircraft engine. It displaces 1,830 cu in (30.0 L) and its bore and stroke are both 5.5 in (140 mm). The design traces its history to 1929 experiments at Pratt & Whitney on twin-row designs. Production began in 1932 and it was widely used during the 1930s.
The Pratt & Whitney R-985 Wasp Junior is a series of nine-cylinder, air-cooled, radial aircraft engines built by the Pratt & Whitney Aircraft Company from the 1930s to the 1950s. These engines have a displacement of 985 in 3 (16 L); initial versions produced 300 hp (220 kW), while the most widely used versions produce 450 hp (340 kW).

The R-2000 was an enlarged version of the Pratt & Whitney R-1830 Twin Wasp, with focus on reducing the manufacturing costs and fuel requirements.The bore was increased to 5.75 in (146 mm), while it still retained the 5.5 in (140 mm) stroke.
