The XC-01 is a prototype aircraft seen in Ace Combat X: Skies of Deception. It appears in Joint Operation (before destroying Nevera Jammer) and Break In, before destroying the factories and stopping the A.L.C. They take place over Monte Breeze.
The XC-01 is a transport aircraft used to deliver the M.B.S.R. to the former Aurelian Capital of Griswall. The M.S.B.R. is intended for to enhance the Meson cannon powered by the Gaiuss tower in the middle of the city. The XC-01's carrying the M.S.B.R.'s for Griswall were all shot down by Gryphus squadron over Monte Breeze. For defense, these XC-01's were escorted by fighters such as MiG-31 Foxhounds, Mirage 2000Ds, MiG-29A Fulcrums, and FB-22s. However, the XC-01 is not entirely defenseless, as the M.B.S.R it carries can be fired out of the cargo bay doors at the back.
Most of the other statistics and flight characteristics for the XC-01 are unknown, since it is an un-playable aircraft and only appears in one mission. However, the size and weight of its cargo undoubtedly makes it slow and an easy target. The XC-01 is very similar to the C-X, which is still being tested by Japan.
There is a common misconception that the XC-01 can fire a TLS during the missions it is encountered. While the beam does share a remarkably similar appearance, sound, and player damage with the TLS, it is in fact the M.B.S.R. firing on a very low yeld, probably on embarked power reserves. Once coupled with the Meson Cannon Array, the M.B.S.R. becomes much more fearsome.
