RIM-161 Standard SM-3
A U.S. naval anti-ballistic missile (ABM) with demonstrated capability against satellites. It is fired from the Vertical Launch System of ships equipped with the [AEGIS Battle Management System]] and AN/SPY-2 ABM radar. As opposed to having the high-explosive warhead of SM-2 anti-air missiles, it kills an incoming warhead or orbiting satellite by colliding directly with the target, a collision with sufficient kinetic energy to vaporize the target and the interceptor.
The missile is the actual kill mechanism of the Navy theater ballistic missile defense system. It is deployed aboard Ticonderoga class cruisers, and could be added to Burke class destroyers. It is being sold, along with the associated radars and computers, to Japan for use aboard Kongo class destroyers, which are a Japanese-manufactured version of the Burke class.
Operational use
SM-3 equipped U.S. ships were deployed in the Sea of Japan during North Korean intercontinental ballistic missile tests. Later, in December 2007, An SM-3 was fired successfully from the Japanese destroyer JDS Kongo, hitting its target. Japan sees the system as a deterrent against North Korea and China.
In February 2008, a SM-3 fired from USS Lake Erie successfully destroyed a U.S. reconnaissance satellite whose orbit was decaying. The U.S. explanation was that if the satellite had entered and not burned up, as intended, during atmospheric reentry, toxic station-keeping propellants on the satellite could be a hazard to people on Earth.
