Pratt & Whitney Wasp 1340

One of the most successful aircraft engines ever designed, 34,966 R-1340 Wasp’s were built between 1925 and 1960.

The engine powered numerous aircraft, the most well known in Canada being the North American Harvard. The distinctive roar of the Harvard comes from this wonderful radial engine coupled to its nine foot Hamilton Standard propeller. Even today its distinctive growl overhead never fails to spark memories in those who heard it many decades ago.
