The F-100A was an early variant of the famous "Super Sabre". In Taiwanese service, it received a number of upgrades to bring it up to par with later models from the USAF, replacing the vertical stabilizer and avionics to F-100D standard. Compared to the fighter-bomber F-100D, it had a smaller wing with a straight trailing edge, fewer hardpoints, and no flaps. Due to the end of major aerial combats during the Taiwan Strait Crisis, the jets were usually used for CAP flights over Taiwan Island or training missions. While it was still a valuable supersonic fighter in the ROCAF fleet into the 1980s, lack of maintenance crew, spare parts, and three consecutive crashes meant that the aircraft were quickly withdrawn in 1984 and replaced by the F-104G and F-5E.

Introduced in Update 1.97 "Viking Fury", the F-100A's handling generally feels lighter than the F-100D and it enjoys a better roll rate, though the lack of flaps impacts low-speed manoeuvrability. The weapons selection is inferior: while it still has access to options like the AGM-12B Bullpup and the AIM-9E Sidewinder, its bomb selection is far more limited and it lacks access to unguided rockets. Still, it has a very solid gun armament of four 20 mm M39A1 cannons. With careful speed management, the F-100A can swoop in and swiftly take down its enemies.
