Evaluation tests have shown that he has excellent teaching and training for machine control, but should be non-retractable landing gear, and the propulsion system is not as powerful. The company "Vulti" promptly finalized the airplane and engine "Wasp Junior" Company "Pratt & Whitney." The end result was the aircraft Tu-13 «Velient", and in September 1939 years 300 USAF ordered aircraft.

The subsequent modification of the engine is equipped with another embodiment of the "Wasp Junior", was made in the amount of 6407 aircraft under the designation BT-13A. In fact, the pace at which built gliders of this aircraft led to a shortage of engines companies "Pratt & Whitney", which forced the company to "Vulti" build aircraft Tu-15 with radial engine R-975-11 «Uirlvind» 9 of "Wright" . The US Navy also received more than 1500 aircraft "Velient" received depending on the configuration engine designations SNV-1 / -2.
