, as one with some of the greatest growth and development prospects available anywhere for the next few decades. It lent Rentschler $250,000, the use of the Pratt & Whitney name, and space in their building. This was the beginning of the Pratt & Whitney Aircraft Company. Pratt & Whitney Aircraft's first engine, the 425 horsepower (317 kW) R-1340 Wasp

. Eventually a whole Wasp series was developed. Both engines are still in use in agricultural aircraft around the world and produce more power than their original design criteria. (Replacement parts for both engines are still in production and it is theoretically possible to assemble a new engine from the parts.)

George Mead soon led the next step in the field of large, state-of-the-art, air-cooled, radial aircraft engines (which the Wasp dominated) when Pratt & Whitney released its R-1690 Hornet. It was basically "a bigger Wasp".
