Ace Combat 8 Database
MiG-31B Foxhound 
A large interceptor that boasts high speeds on a world-class scale. The B-model is fitted with enhanced avionics. It was developed as a replacement for the MiG-25, which was designed as a countermeasure against bombers attacking at high altitudes. It was designed to be able to attack at low altitudes and, in particular, to take out cruise missiles and the craft that fired them. Additionally, it was envisioned that the craft would provide long-distance support for bombers. Capable of carrying long-range anti-air missiles, its high-speed capabilities make it an ideal craft for providing a follow-up attack to an opening gambit against hostiles. However, it was not built for close-range combat, so its large turning radius can be a disadvantage.

Flight model
The raw flight data from the game files (campaign version). Speeds are in km/h. The other numbers use the game's own units. The values keep the game's field names, because what most of them do is still unknown. Under Stability and Defense are the fields that match those in-game bars best. Mobility matches the rotation rates. How the game calculates the bars is unknown.
The game's curve points for this aircraft are out of order (a lower speed follows a higher one); they are drawn as stored.
