Several variants were produced; the BT-13, BT-13A (SNV-1) and BT-13B (SNV-2) were powered by a 450 h.p. P&W R-985 Wasp Junior radial engine, whereas the BT-15 was fitted with the nine-cylinder 450 h.p. Wright Whirlwind R-975 engine. Production ceased in 1944 after 11,537 Valiants had been built for the USAAF and U.S. Navy. This Valiant served in AURI's flying school from 1951 and went to the museum in 1985.
