XFA-27

The XFA-27 is the first "super fighter" in the history of Ace Combat. It's "maiden flight" (so to speak) was in Ace Combat 2, where it is unlocked by the player if he/she uses the post-endgame Extra Mode (unlocked by finishing the game), starting a New Game in Hard, making your way to the mission Dead End, and destroying the YF-23A "Fox Force Four" squadron (which will also earn the player a medal).

The XFA-27 is the first fighter to use variable geometry, stealth, advanced weapon systems and a new propulsion system, which is still classified and has never been re-created. The initial version of the XFA-27 (seen in AC2) had a weapons system which allowed it to fire four missiles in rapid succession. The version seen in Ace Combat X, however, no longer has this ability unless it is "tuned" with the Scarface MBS weapon part.

The engines in the XFA-27 use classified technology and possibly a special fuel. It has an extremely small turn radius, powerful acceleration and its thrust to weight ratio is thought to be extremely high. The unusual deep blue colour of its afterburner, as opposed to the more standard yellow-orange, may indicate the intensity of the heat being given off by the special engine/fuel combination. Its unique afterburner colour and capability to fire four missiles rather than the standard two, are the XFA-27's signature.

Its cockpit does use Connection for Flight Interface technology, but not fully like most advanced aircraft seen in the Ace Combat series. It uses a unique and unconventional glass-fronted cockpit. And below it are 1 (or 2) small cameras that uses the COFFIN system. The majority of instruments have been removed with only a bar housing essential displays remaining. This increases the pilot's visibility by a considerable amount. In a sense, this is another way to increase battle effectiveness rather than installing COFFIN technology.
