The Vultee BT-15 was the final and most produced version of the Vultee basic trainer family, following the BT-13 and BT-14. Introduced during World War II, the BT-15 was an advanced version used to train thousands of U.S. Army Air Forces pilots in the early and mid-stages of their flight training. Its rugged design, wide landing gear, and responsive controls made it ideal for teaching cadets how to handle higher-performance aircraft.
Nicknamed the "Vibrator" by trainees due to its tendency to shake during certain maneuvers, the BT-15 was known for its toughness and reliability. Although it was not armed, it played a vital role in shaping the skills and instincts of America’s WWII aviators before they transitioned to fighters or bombers. The BT-15 was powered by a more powerful Wright R-975 engine compared to its predecessor, and it had reinforced airframe improvements to accommodate increased weight and better flight stability.
Many BT-15s were sold on the surplus market after the war and are still flown today as warbirds or featured in aviation museums and airshows, preserving their legacy as a critical stepping stone in pilot training history.
