The Waco CG-15 was another development of the Waco CG-4 Hadrian standard glider. Waco had essentially developed an improved version of the CG-4A. The changes consisted of a reduction in the wing span from 83 ft 8 in to 62 ft 2 in, elimination of the wing spoilers, a revised nose shape, improved cantilever undercarriage and numerous internal fitment changes. The changes increased the normal gross weight by 500 lbs (227 kg) and the towing speed increased to 180 mph (290 km/h). 427 CG-15 gliders were originally delivered to the US military. Canada acquired a single example for evaluation purposes.
