S-500 (missile system)

The S-500 Prometey (Russian: C-500 Прометей, Prometheus), also known as 55R6M "Triumfator-M", is a Russian surface-to-air missile/anti-ballistic missile system intended to replace the A-135 missile system currently in use, and supplement the S-400. The S-500 is under development by the Almaz-Antey Air Defence Concern, and planned to be deployed by 2020. With its characteristics it will be very similar to the US Terminal High Altitude Area Defense system.

The S-500 is a new-generation surface-to-air missile system. It is designed for intercepting and destroying intercontinental ballistic missiles, as well as hypersonic cruise missiles and aircraft, for air defense against Airborne Early Warning and Control and for jamming aircraft. With a planned range of 600 km (370 mi) for anti-ballistic missile (ABM) and 400 km (250 mi) for the air defence, the S-500 would be able to detect and simultaneously engage up to 10 ballistic hypersonic targets flying at a speed of 5 kilometres per second (3.1 mi/s; 18,000 km/h; 11,000 mph) to a limit of 7 km/s (4.3 mi/s; 25,000 km/h; 16,000 mph). It also aims at destroying hypersonic cruise missiles and other aerial targets at speeds of higher than Mach 5, as well as spacecraft. The altitude of a target engaged can be as high as 180–200 km (110–120 mi). It is effective against ballistic missiles with a launch range of 3,500 km (2,200 mi), the radar reaches a radius of 3,000 km (1,300 km for the EPR 0,1 square meter).

The system will be highly mobile and will have rapid deployability. Experts believe that the system's capabilities can affect enemy intercontinental ballistic missiles at the middle and end portions of flight, but reports by Almaz-Antey say that the external target-designation system (RLS Voronezh-DM and missile defense system A-135 radar Don-2N) will be capable of mid-early flight portion interceptions of enemy ballistic missiles, which is one of the final stages of the S-500 project.
