Background
Several Visiontrons at Nellis Air Force Base are mentioned by the Boomers to be running flight simulators, and that they are using the simulations to train themselves to fly. Pete mentions these simulations include combat flights against Xian-85's, and that he has personally shot down over 500 of them during his VR sessions.

Appearances
The Xian-85 fighter is mentioned only in Fallout: New Vegas.

Behind the scenes
"Xian" may be a reference of the real-life XAC, Xi'an Aircraft Industrial Corporation, a major Chinese military and civilian aircraft manufacturer.
