VULTEE BT-13 VALIANT
The Valiant was the basic trainer most widely used by the U.S. Army Air
Forces during World War II. It represented the second of the three stages of
pilot training -- primary, basic and advanced. Compared with
the primary trainers in use at the time, it was considerably more complex. The
BT-13 not only had a more powerful engine, it was also faster and heavier. In
addition, it required the student pilot to use two-way radio communications
with the ground and to operate landing flaps and a two-position variable pitch
Nicknamed the "Vibrator" by the pilots who flew
it, the BT-13 was powered by a 450-hp Pratt & Whitney R-985 engine.
Because of a shortage of these engines, however, 1,693 Valiants flew with
Wright R-975 engines, thereby becoming BT-15s. By the end of WWII, 10,375
BT-13s and BT-15s had been accepted by the USAAF.
The BT-13B on display, one of 1,775 Bs built, was acquired
from Raymond Brandly of West Carrollton,
Ohio, in 1965.
