There was an interesting version of the F-16 manufactured and flown in the 1980s. It used a swept wing design known a cranked arrow wing to change the plane's flight characteristics.
General Dynamics made a proposal for a Fighting Falcon version with a modified wing shape, that was originally proposed for use on supersonic airliners. The project was known as SCAMP (Supersonic Cruise and Maneuvering Program). The delta wing was a cranked-arrow shape, with a total surface of 633 sq. ft. (more than double the area of the standard F-16 wing). The research objectives included exploring innovative wing forms and camber shapes to provide efficient supersonic cruise performance while providing fighter-like transonic and supersonic turn agility. The design was intended to offer low drag at high subsonic or supersonic speeds without compromising low-speed maneuverability. It also provided a large weapons mounting platform. It also provided a large area for weapons deployment.
