The North American NA-35 was a
training aircraft designed by
North American Aviation. It was first test-flown in January 1940 by
Vance Breese. Although announced for trade the month after, the project was pushed aside by plant expansions and the development of the
P-51 Mustang. Further test flights were conducted and construction began on a few more aircraft, but the project remained stagnant until
Vega Aircraft Corporation bought the rights to the aircraft in October 1940 to develop into the Vega 35.
