The NPO Almaz S-200 Angara/Vega/Dubna, NATO reporting name SA-5 Gammon, is a long-range, high-altitude surface-to-air missile (SAM) system developed by the Soviet Union in the 1960s to defend large areas from high-altitude bombers or other targets. In Soviet service, these systems were deployed primarily on the battalion level, with six launchers and a fire control radar.
