Originally developed by McDonnell in 1964, the F-103 began as a hybridization of the F-101 Voodoo and the F-4 Phantom II. The XA-13A, as it began, was to be a high speed single seat attacker for the USAF. In it's flight trials, it performed perfectly...a little too perfectly. Officials from the USAF and USN noticed the aircraft's startling maneuverability. It was uncany. Tests were ran with Phantoms, Crusaders, and multiple century series jets. The XA-13A ran rings around everything. Without ant hesitation, the second prototype was modified to that of a fighter/interceptor. It quickly went on to break multiple records, and entered service as the F-103A. Production ran for 25 years (1967-1992). Total numbers came to 9,897. Operators include: The USA, Canada, Mexico, Denmark, Germany, Australia, Japan, Taiwan, and France (France meant for them to be an interim solution, but due to their capabilities, they actually bought more). Use group 1 for lights, and group 2 for the Arrestor Hook.
