For control, a canard forward of the wing was used as well as split ailerons and an advanced thrust vectoring nozzle for directional control. The X-36 was unstable in both pitch and yaw axes, so an advanced digital fly-by-wire control system was put in place to stabilize the aircraft.
First flown on May 17, 1997, it made 31 successful research flights. It handled very well, and the program is reported to have met or exceeded all project goals.
The aircraft is sometimes referred to as the Boeing X-36 as the test program was still in progress when McDonnell Douglas merged with the Boeing Company. In the adjoining photograph it is carrying Boeing markings.
