In 1983, DARPA began working with the U.K. Ministry of Defense (MoD) to develop a follow-on supersonic generation to the AV-8 Harrier, a pioneer aircraft for short takeoff and landing (STOL) capabilities. The international program that emerged from this intention, the Advanced Short Takeoff Vertical Landing (ASTOVL), expired in 1991, but various component efforts toward the same end continued. For its part, DARPA worked with the U.S. Navy to establish a development program for an STOVL Strike Fighter with capabilities specified by the Navy in 1988. The program evolved toward an aircraft that could build on much of the design base for the Air Force F-16.
In 1992, DARPA and the Navy initiated a revised ASTOVL program with an objective of demonstrating an affordable STOVL strike fighter for the U.S. Marine Corps with a conventional takeoff and landing version for possible U.S. Air Force service. In 1993 and 1994, this morphed into the DARPA-managed Common Affordable Lightweight Fighter (CALF) and into subsequent evolutionary incarnations managed by other Department of Defense entities.
