Appearances "The last hope for the Special Tactical Fighter Squadron Scarface . . . All information on this aircraft remains classified at the highest level" ā Ace Combat Facebook page[2] The XFA-27 is a unique multirole aircraft. It was one of the first original aircraft designs to be featured in an Ace Combat game, specifically Ace Combat 2 in 1997, alongside the ADF-01 FALKEN and XB-10. Since its original appearance, it has mostly been restricted to handheld titles. In March 2015, the XFA-27 was added to Ace Combat Infinity, its first home console appearance in 18 years. Along with the R-101 Delphinus #1, the XFA-27 was a late-game aircraft available at the far end of the Aircraft Tree, requiring an exorbitant amount of credits to unlock and upgrade.
