In 1946, the Canadian Car and Foundry developed the Harvard Mk IV
trainer to the specifications of the North American Aviation AT-6G "Texan".
Production began in 1951. 555 Mk IVs were produced for Canada and the US in
the 1950s. It was an advanced trainer with hydraulic gear and flaps. The
aircraft is stressed for aerobatics and is capable of most maneuvers, except
sustained inverted flight, snap rolls, outside loops, and inverted spins.
137,000 aircrew came to Canada from all corners of the globe to earn their
wings in the British Commonwealth Air Training Plan. The "roar" of the Harvard
comes from its 600 HP Pratt & Whitney engine coupled to its 9-foot Hamilton
Standard propeller with tips reaching sonic speeds. In the 1950s, some Harvard
MK IVs served NATO countries in Europe under the designation T-6J.
