Pratt & Whitney Machine Tool was going through a period of self-revision at the time to prepare itself for the post-World War I era, discontinuing old product lines and incubating new ones. World War I had been profitable to P&WMT, but the peace brought a predictable glut to the machine tool market, as contracts with governments were canceled and the market in used, recently built tools competed against new ones.

and civil (commercial, private), as one with some of the greatest growth and development potential available anywhere for the next few decades. It lent Rentschler US$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, was completed on Christmas Eve 1925. On its third test run it easily passed the U.S. Navy qualification test in March 1926; by October 1926, the U.S. Navy had ordered 200. The Wasp exhibited performance and reliability that revolutionized American aviation. The R-1340 powered the aircraft of

, and many other record flights. The R-1340 was followed by another very successful engine, the R-985 Wasp Junior. 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. 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". In 1929, Rentschler ended his association with Pratt & Whitney Machine Tool and merged Pratt & Whitney Aircraft with
