A Raytheon Company Standard Missile-2 (SM-2) Block IV with control systems upgrades was successfully flight tested against a subsonic target at White Sands Missile Range, New Mexico, February 16. The upgrades will provide the U.S. Navy with improved performance at a lower cost.

The SM-2 Block IV upgrade includes a new steering control section, new thrust vector actuator assembly for the boost rocket motor and a new primary missile battery as well as upgrades to the guidance and control software. The upgrade was completed as part of a value engineering project at Raytheon Missile Systems in Tucson, Arizona. The improvement will result in a significant cost reduction of the missile.

SM-2 is launched from cruisers and destroyers. The missile has enhanced precision and kinematics throughout the threat envelope as well as improved countermeasures performance. The SM-2 Block IV upgrades are applicable to all extended-range Standard Missile variants, including SM-3 and SM-6.
