Standard Missile-2

Standard Missile-2 (SM-2) is the world’s premier fleet-area air defense weapon, providing superior anti air warfare (AAW) capability against today’s advanced anti-ship missiles and aircraft out to 90 nautical miles and an altitude of 65,000 feet. Its demonstrated mission is medium range and fleet-area (the area surrounding a ship) air defense and limited anti-surface warfare. SM-2 is an integral part of a layered defense protecting the world’s important naval assets and gives warfighters a greater reach in the battle space.


  • Advanced semi-active radar seeker technologies in both continuous wave and interrupted continuous wave guidance modes
  • Tail controls and solid rocket motor propulsion to engage the world’s advanced high-speed maneuvering threats at tactically significant ranges.
  • SM-2 IIIB enhances the IIIA’s existing superior capabilities by adding autonomous IR acquisition.
  • High-technology active radar target detection device and directional warhead to ensure successful destruction of the target.

Both SM-2 variants have successfully intercepted and are lethal against subsonic, supersonic, low- and high- altitude, high-maneuvering, diving, sea-skimming, anti-ship cruise missiles fighters, bombers and helicopters in an advanced Electronic Counter Measures (ECM) environment. SM-2 has extensive area- and self-defense flight test history with more than 2,650 successful flight tests from domestic and international ships

The SM-2 missile is supported by Intermediate Level Maintenance Facilities worldwide, including locations in Australia, Japan, the Netherlands, the Republic of Korea, Taiwan and the United States. These maintenance facilities use state-of-the-art MK-698 test equipment to recertify and maintain All Up Round missiles at locations close to the user Navy, minimizing downtime for those missiles. Section-level maintenance is performed in the United States, when required.

The SM-2 family continues to grow internationally: Australia, Canada, Germany, Japan, Korea, the Netherlands, Spain and Taiwan have deployed SM-2 capable ships; Australia’s Air Warfare Destroyer will employ SM-2; and several other navies are defining requirements and ship configurations to support SM-2 applications.
