Mig-31 had a major engine fire
Isn't that the normal operating state of the Foxbat family?
Tap for explanation
MiG-25 engine service life is 150 hours, MiG-31 300 hours.
These engines are essentially burning themselves to death constantly.
For comparison: the 🇨🇵Rafale engine, the Snecma M88-2, has a time between overhauls of 3000 hours, and is designed for a service life of 6000 hours.
Twice as long as a cruise missile apparently 🤣
