Russia’s Su-57 Felon Stealth Fighter Is Getting New Air-To-Air Missiles

The R-77 medium-range air-to-air missile is the Russian equivalent of the radar-guided U.S. AIM-120 AMRAAM (Advanced Medium-Range Air-to-Air Missile). The R-77 was first introduced in 1991 but it had a severely protracted development. The improved R-77-1 entered service with the Russian Air Force in 2015, and it has been employed on Su-35S fighters in Syria and used during combat air patrols.
