The Vympel NPO R-77 missile (NATO reporting name: AA-12 Adder) is a Russian active radar homing beyond-visual-range air-to-air missile. It is also known by its export designation RVV-AE. It is the Russian counterpart to the American AIM-120 AMRAAM missile.
The R-77 was marked by a severely protracted development. Work began in the 1980s, but was not completed before the Soviet Union fell. For many years, only the RVV-AE model was produced for export customers. Production was further disrupted when the Russo-Ukrainian War resulted in a Ukrainian arms embargo against Russia, severing supply chains. The Russian Aerospace Forces finally entered the R-77-1 (AA-12B) into service in 2015. It was subsequently deployed by Su-35S fighters in Syria on combat air patrols. The export model of the R-77-1 is called RVV-SD.
