Two F-16XLs were built as conversions from Full Scale Development aircraft. The No. 1 aircraft (S/N 75-0749) was a single-seat version while No. 2 (S/N 75-0747) was a two-seat version. The aircraft were flight tested from mid-1982 through 1985 before being put into storage. The No. 1 aircraft was pulled from storage in 1989 and modified for test work with NASA for studies on supersonic laminar flow and sonic boom research (in conjunction with an SR-71). The second aircraft was returned to service at the Dryden Flight Research Center in 1992 and took over the supersonic laminar flow project from aircraft No. 1.
The F-16XL is a radically different version of the standard F-16. The most obvious design change is the "Cranked-arrow" double delta wing. The aircraft is also more than four feet longer than the production F-16A. The XL was initially intended as a multi-role strike aircraft competing against the F-15E Strike Eagle. The F-16XL never entered production, and only the two prototypes were built.
