The RIM-161 Standard Missile 3 (SM-3) is a ship-based missile system used by the US Navy to intercept short-to intermediate-range ballistic missiles as a part of Aegis Ballistic Missile Defense System. Although primarily designed as an anti-ballistic missile, the SM-3 has also been employed in an anti-satellite capacity against a satellite at the lower end of low Earth orbit. The SM-3 is primarily used and tested by the United States Navy and also operated by the Japan Maritime Self-Defense Force.
On 13 June 2002, the United States withdrew from the Anti-Ballistic Missile Treaty and recommenced developing missile defense systems that would have formerly been prohibited by the bilateral treaty. The action was rationalized under the need to defend against the possibility of a missile attack conducted by a rogue state. The next day, the Russian Federation promptly dropped the START II agreement, intended to completely ban MIRVs.
The new SM-3 capabilities are :
Operational range Block IIA ~2500 km (1350 nautical miles)
Flight ceiling Block IIA ~1500 km (933 miles)
Speed Block IIA ~4.5 km/s
Lockheed is pushing for funding for the development of an ER (extended range) version of the THAAD (Terminal High Altitude Area Defense) to counter maturing threats posed by hypersonic glide vehicles adversaries may employ, namely the Chinese WU-14, to penetrate the gap between low and high-altitude missile defenses.
Russian has a new antiballistic missle called the S500. It should appear in 2017.
The new Russian S500 is rumored to be able to engage 10 missiles at once and have a refined radar system, as well as make speeds of up to 4.3 miles per second. It’s also expected to rival US tech, which currently touts the RAS3 Patriot missile defense system against the S400.
The S-500 is a new generation surface-to-air missile system, designed for intercepting intercontinental ballistic missiles and for defense against Airborne Early Warning and Control, Airborne Warning and Control System, and jamming aircraft. It is not an upgraded version of the S-400. With a planned range of 600 km (373 mi) Anti Ballistic Missile (ABM) and 400 km for the air defense, the S-500 would be able to detect and simultaneously engage up to 10 ballistic supersonic targets flying at a speed of 5 km/s, limit of 7. 6 years later have already spoken of height of 185 km and range of 3500, (3500 or more).

In 2015, Russia will test its ‘Sarmat’ missile, expected for shipment before 2020. According to the senior official, “the missile is capable of delivering a 10-ton payload.” The super heavy liquid-propelled intercontinental ballistic missile (ICBM) has also received upgrades. “It will be able to fly over both the North and South Poles.”
