This is a reupload because I accidentally deleted the original one.

I had been working with Johndfg, one of the best users on this site, to make the MiG-31 Foxhound.
It comes with no weapons, a la the original design to preserve the original build. Feel free to add any weapons. Keep in mind that this was built in 1.6-1.5 so it may not be it to today's standards.

Wikipedia:
"The Mikoyan MiG-31 (NATO reporting name: Foxhound) is a supersonic interceptor aircraft developed for use by the Soviet Air Forces. The aircraft was designed by the Mikoyan design bureau as a replacement for the earlier MiG-25 "Foxbat"; the MiG-31 is based on, and shares design elements with the MiG-25. The MiG-31 has the distinction of being one of the fastest combat jets in the world. It continues to be operated by the Russian Air Force and the Kazakhstan Air Force following the end of the Cold War and the collapse of the Soviet Union in late 1991. The Russian Defence Ministry expects the MiG-31 to remain in service until at least 2030."

Again, this is a reupload, so I tried to preserve the original design, only adding a unlimited fuel tank, which was in the original or so it seems.
Please upvote as I had made a very big mistake deleting the original. Keep looking for more new builds and happy flying!
