@pirate1.0: The MiG-31 Foxhound is a Soviet-era supersonic interceptor designed to defend vast northern territories against cruise missiles and bombers, entering service in 1981 as a heavy upgrade to the MiG-25. Its core innovation is the Zaslon passive electronically scanned array radar—the world’s first on a fighter—enabling it to track up to 10 targets and engage 4 simultaneously at extreme ranges. Powered by two powerful D-30F6 turbofans, it is one of the fastest combat jets in service, capable of Mach 1.23 at sea level and Mach 2.83 at altitude, often flown with four R-33 long-range air-to-air missiles. Uniquely for an interceptor, it is designed for solo long-endurance patrols and can coordinate with other MiG-31s via a data link to cover vast gaps without ground radar. Though large and resource-intensive, its ability to hunt stealth bombers and cruise missiles has kept it in service, with modernized MiG-31BM variants and the hypersonic-missile-carrying MiG-31K forming a key part of Russia’s strategic defense today. #mig31foxhound #mikoyan #sovietunion
