A member of the Standard SM missile series, the RIM-156 Standard, also known as the SM-2ER Block IV, is a long-range naval surface-to-air missile principally designed to be fired from vertical launch system|Vertical Launch Systems (VLS) on ships equipped with the AEGIS battle management system.

The earlier SM-1 variants were fired from launch rails, not vertical launchers. Its launch is controlled by the Mark 99 fire control system, its initial and midcourse guidance comes from from a SPY-1|AN/SPY-1 AEGIS search radar, and it uses terminal semi-active radar homing from an SPG-62|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.

VariantsModifications of the SM-2 are called blocks. SM2 block IVA is a SM2 Block IIIb with a short but exceedingly powerful booster attached. Booster length was limited by the maximum length of a VLS cell. With the booster, the range extends to 150 mi. It can over-the-horizon anti-ship missile, nearly replacing Harpoon on the Ticonderoga-class, and supplanting it entirely on the Arleigh Burke-class. It has a smaller warhead than the AGM-84 Harpoon, but the missile itself is much larger and faster; the total kinetic energy with the warhead is greater than that of the Harpoon. It is, however, expensive, and less maneuverable at short range than the Block IIIb; a ship may carry a mixture of the blocks.
