R-40 (missile)

The Bisnovat (later Molniya then Vympel) R-40 (NATO reporting name AA-6 'Acrid') was a long-range air-to-air missile developed in the 1960s by the Soviet Union specifically for the MiG-25 interceptor, but can also be carried by the later MiG-31. It is the largest air-to-air missile in the world to ever go into production.
