Anyone done this one? if not, it is a request.
During the 1970s, Saab proposed a new variant of the Viggen, designated the Saab 37E Eurofighter (unrelated to the later Eurofighter Typhoon), for the United States Air Force's Air Combat Fighter competition to find a replacement for the Lockheed F-104 Starfighter. The 37E Eurofighter competed against Dassault-Breguet's proposed Mirage F1M-53, the SEPECAT Jaguar, Northrop's P-530 Cobra (based on the Northrop YF-17), and General Dynamics's YF-16;[90][91] on 13 January 1975, Secretary of the Air Force John L. McLucas announced the YF-16 had been selected as the winner of the ACF competition.[92]
