Almost all had pushed an unproven supersonic aircraft to the edge of its capabilities.

All non-delta-winged supersonic aircraft use stabilators because with conventional control surfaces, shock waves can form past the elevator hinge, causing severe mach tuck.

Supersonic aircraft had to be made capable of adjusting sufficiently, in order to maintain adequate control at all stages of flight.

The investigations in these facilities greatly contributed to the development of supersonic aircraft.

This will also be referred to as military aircraft nozzles and represents the nozzle thrust vectoring control applicable to fighter and other supersonic aircraft.
