Standard Missile

 
Description
Medium-long range shipboard surface-to-air missile.
 
Background
Standard Missile 2 (SM-2) is the U.S Navy's primary surface-to-air air defense weapon. It is an integral part of the Aegis Weapon System (AWS) aboard Ticonderoga-class cruisers and Arleigh Burke-class destroyers, and is launched from the MK 41 Vertical Launcher System (VLS). Its primary missions are fleet area air defense and ship self-defense, but it also has demonstrated an extended area air defense projection capability. The SM-2 uses tail controls and a solid fuel rocket motor for propulsion and maneuverability. All variants are guided by inertial navigation and mid-course commands from AWS using semi-active radar or an IR sensor for terminal homing.

SM-2 Blocks III, IIIA, IIIB, and IV are in service with the U.S. Navy; these and other variants of Standard Missile are also in service with 15 allied navies.

SM-6 Extended Range Active Missile provides an air defense force multiplier to the U.S. Navy to greatly expand the AWS battlespace. Combining a modified AMRAAM active seeker onto the proven Standard Missile airframe, SM-6 provides an extended range anti-air warfare capability both over sea and over land. This low-risk approach relying on non-developmental items supported a FY 2011 Initial Operating Capability. With integrated fire control support, SM-6 provides the Navy with an increased battlespace against Anti-Air Warfare (AAW) threats over-the-horizon.
