General Dynamics F-16XL NASA

The F-16XL aircraft were built by General Dynamics as prototypes for a derivative fighter evaluation program conducted by the Air Force between 1982 and 1985. The aircraft were developed from basic F-16 airframes, with the most notable difference is the delta (cranked arrow) wing which give the aircraft a greater range because of increased fuel capacity in the wing tanks, and a larger load capability due to increased wing area. The F-16XL was able to take off and land in two thirds of the distance required by the F-16A. It was capable of speeds of 90 knots greater than the F-16A at sea level and had a 125% greater range than an F-16A with the same payload.
