Boeing Phantom Works manufactured two airframes. They flew a total of 33 flights between 1997-1998. This Tailless Fighter Agility Research Aircraft demonstrated the feasibility of future tailless fighters to achieve levels of agility superior to today’s best military fighter aircraft. These 28-percent-scale, remotely-piloted X-36s participate in a program featuring a tailless configuration to reduce the radar signature of the aircraft. In a follow-on effort, the Air Force Research Lab (AFRL) contracted with Boeing to fly AFRL’s Reconfigurable Control for Tailless Fighter Aircraft (RESTORE) software as a demonstration of the adaptability of the neural-net algorithm to compensate for in-flight damage or malfunction of effectors, i.e., flaps, ailerons and rudders. Two RESTORE research flights were flown in December 1998, proving the viability of the software approach.
