The General Dynamics F-16XL is a derivative of the F-16 Fighting Falcon with a cranked-arrow delta wing. It entered the United States Air Force's (USAF) Enhanced Tactical Fighter (ETF) competition in 1981 but lost to the F-15E Strike Eagle. The two prototypes were shelved until being turned over to NASA for additional aeronautical research in 1988.
On 11 October 2018, an F-16 MLU from the 2nd Tactical Wing of the Belgian Air Component, on the apron at Florennes Air Station, was hit by a gun burst from a nearby F-16, whose cannon was fired inadvertently during maintenance. The aircraft caught fire and was burned to the ground, while two other F-16s were damaged and two maintenance ...
The F-16XL featured a novel 'cranked-arrow' type of delta wing with more than twice the area of the standard F-16 wing. Developed under a program originally known as the Supersonic Cruise and Maneuvering Program (SCAMP), the design was intended to offer low drag at high subsonic or supersonic speeds without compromising low-speed maneuverability.
The single-engine F-16XL has major structural and aerodynamic differences from the original F-16 Fighting Falcon, resulting in a promising design which, with its radically redesigned cranked-delta wing, greatly boosted performance; if selected, the single- and two-seat versions were to be designated F-16E and F-16F, respectively.

In the compound delta, double delta or cranked arrow, the leading edge is not straight. Typically the inboard section has increased sweepback, creating a controlled high-lift vortex without the need for a foreplane. Examples include the Saab Draken fighter, the experimental General Dynamics F-16XL, and the
Cranked arrow: aerodynamically identical to the compound delta, but with the trailing edge also kinked inwards. Trialled experimentally on the General Dynamics F-16XL . M-wing : the inner wing section sweeps forward, and the outer section sweeps backwards.
