A member of the Standard SM missile series, the RIM-156 Standard, also known as the SM-2ER Block IV, is aq long-range naval surface-to-air missile designed to be fired from Vertical Launch Systems (VLS) on ships equipped with the AEGIS battle management system. These include the U.S. Ticonderoga-class cruisers, Japanese Kongo-class and U.S. Burke-class destroyers, and Spanish F-100 frigates.
Its launch is controlled by the Mark 99 fire control system, its initial and midcourse guidance comes from from a AN/SPY-1 AEGIS search radar, and it uses terminal semi-active radar homing from an AN/SPG-62 illumination radar.
In a layered anti-air warfare defense, the next defense is the RIM-162 ESSM (Evolved Sea Sparrow Missile), with a range of 27+ nm/50+ km, forms the next band. For final defense, there is the 9 km (5 nm) RIM-116 Rolling Airframe Missile on ships equipped with it, or with the Phalanx close-in weapons system autocannon.
The RIM-161 Standard SM-3 is a variant, which, on AEGIS ships with the appropriate radar upgrades, has successfully destroyed theater ballistic missiles and satellites.
Since the SM-3 does not have a secondary anti-air capability, development was begun on a longer-ranged version RIM-174 Standard SM-6, which is effectively an RIM-156A SM-2 Block IV missile, to which the active radar seeker of the AIM-120C-7 AMRAAM air-to-air missile has been added for terminal guidance. Because of that seeker, the ERAM acronym, in 2008, was redefined to mean Extended Range Active Missile. The active terminal radar replaces the semi-active radar homing of the RIM-156, which now requires the AN/SPG-62 illuminator, which is not over-the-horizon-capable. [1]
