SM-2 Block II/III/IIIA configurations are all-weather, ship-launched medium-range fleet air defense missiles The Standard Missile-2 (SM-2) is the Navy’s primary surface-to-air fleet defense weapon. The currently deployed derived from the SM-1 (RIM-GGB), which is still in the fleet. SM-2 employs an electronic countermeasures-resistant monopulse receiver for semi-active radar terminal guidance and inertial midcourse guidance capable of receiving midcourse command updates from the shipboard fire control system. SM-2 is launched from the Mk 41 Vertical Launching System (VLS) and the Mk 26 Guided Missile Launching System (GMLS). SM-2 continues to evolve to counter expanding threat capabilities, and improvements in advanced high and low-altitude threat interception, particularly in stressing electronic countermeasures (ECM) environments, are being implemented through modular changes to the missile sections.

The Standard Missile was produced in two major types, the SM-1 MR/SM-2 and the SM-2. It is one of the most reliable in the Navy's inventory. Used against missiles, aircraft and ships, it first came into the fleet more than a decade ago. It replaced Terrier and Tartar missiles and is part of the weapons suit of more than 100 Navy ships. The SM-2 (MR) is a medium-range defense weapon for Ticonderoga class Aegis cruisers, Arleigh Burke-class Aegis destroyers, California and Virginia class nuclear cruisers and Kidd class destroyers with NTU conversions. Oliver Hazard Perry-class frigates use the SM-1 MR.

The SM-2 is a solid propellant-fueled, tail-controlled, surface-to-air missile fired by surface ships. Designed to counter high-speed, high-altitude anti-ship cruise missiles (ASCMs) in an advanced ECM environment, its primary mode of target engagement uses mid-course guidance with radar illumination of the target by the ship for missile homing during the terminal phase. The SM-2 can also be used against surface targets. SM-2 Blocks II through IV provide protection against aircraft and antiship missiles, thereby expanding the battlespace.
