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.
75-747 - modified as F-16XL/B with cranked-arrow. On display at the Air Force Flight Test Museum at Edwards Air Force Base near Rosamond, California. [5] 75-748 - on display at the Air Force Academy in Colorado Springs, Colorado. [citation needed] 75-749 - modified as F-16XL/A with cranked-arrow wing.
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.
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.

The F-16E (single seat) and F-16F (two seat) are newer F-16 Block 60 variants based on the F-16C/D Block 50/52. The United Arab Emirates invested heavily in their development. They feature improved AN/APG-80 active electronically scanned array (AESA) radar, infrared search and track (IRST), avionics, conformal fuel tanks (CFTs), and the more ...
Of the second-hand F-16s, five of the airframes were used as spare parts, and only the remaining 20 F-16s were intended for upgrade for day & night all-weather operations, by receiving the Falcon UP structural upgrade, the F100-PW-220E engine upgrade and the Mid-Life update (MLU) avionics and cockpit upgrade, to equip the 301 Squadron.
