In 2011, the DG-1000 was selected by the USAF as a replacement for the Blanik TG-10. It will serve as a basic soaring trainer for cadets at the United States Air Force Academy. It also serves as the primary competition platform for the USAF Academy Aerobatic Demonstration Team. Its USAF designation is TG-16A.[2][3]
