| Mission: Medium-long
range shipboard surface-to-air missile.
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
destroyers, and is launched from the MK 41 Vertical Launcher System
(VLS). Its primary mission is fleet area air defense and ship self
defense, but it also has demonstrated an extended area air defense
projection capability and it has a secondary anti-surface ship mission.
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, and
IIIB are in service with the U.S. Navy; these and other variants of
Standard Missile are also in service with fifteen allied navies.
Extended Range Active Missile, will provide a transformational enabler
to the U.S. Navy to revolutionize Naval Warfare. Combining an AMRAAM
active seeker onto the proven STANDARD Missile
will provide an extended range anti-air warfare capability both over
sea and overland. This low-risk approach relying on non-developmental
items will support a FY 2011 Initial Operating Capability. With
integrated fire control, SM-6 will provide the surface Navy with an
increased battlespace against Anti-Air Warfare (AAW) threats
over-the-horizon, taking full advantage of the kinematics available to STANDARD
