The Su-37 -Yellow13- is a modified version of the Su-37 Terminator with a special skin featuring the livery of Yellow 13. It appeared in Ace Combat Infinity as a Special Aircraft and later returned in Ace Combat 7: Skies Unknown as a skin from F-4E Phantom II "A special version of the Su-37 featuring the same design as an aircraft belonging to an ace pilot of a big nation. Adjustments have been made to improve flight performance to a level which will satisfy all pilots' needs. Yellow 13 was an extremely heroic ace pilot who showed no signs of aggression. He respected pilots with skill, be it ally or enemy. As with many other pilots, he also disappeared into the skies, never to be seen again." The aircraft was only available to the top 1,000 players during the Yellow 13 Ranking Tournament in late September 2014.
