History

The Canadian Pratt & Whitney Aircraft Company, Ltd. was founded in November 1928 to act as a service centre for P&W aircraft engines. During World War II, it assembled

Pratt & Whitney Wasp The Pratt & Whitney Wasp was the civilian name of a family of air-cooled radial piston engines developed in the 1930s, 1940s, and 1950s.Gunston 1989, p.114. The Pratt & Whitney Aircraft Company (P&W) was founded in 1925 by Frederick B. Rentsch ...

series engines built in the U.S. In 1952, the production of Wasp engines was transferred to Canadian Pratt & Whitney so P&W could concentrate on developing jet engines. In the late 1950s, a team of 12 Canadian Pratt & Whitney engineers began the development of the first small turbine engine in Canada, the PT6. The first example was delivered to a customer in 1963. In 1962, the company was renamed United Aircraft of Canada (UAC), and assumed its current name in 1975. In 1963 a total of 41

Its 100,000th engine was produced in May 2017, its fleet logged 730 million flight hours and 60,000 in-service engines are operated by 12,300 customers in more than 200 countries.
