The Standard Missile-2 is the world’s premier fleet-area air defense weapon, providing superior anti-air warfare and limited anti-surface warfare capability against today’s advanced anti-ship missiles and aircraft out to 90 nautical miles and an altitude of 65,000 feet. SM-2 is an integral part of layered defense that protects the world’s important naval assets and gives warfighters a greater reach in the battlespace.
SM-2 Block IIIA and IIIB features
- 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
- IIIB enhances the IIIA’s existing superior capabilities by adding autonomous infrared acquisition
- High-technology active radar target detection device and directional warhead to ensure successful destruction of the target
Both SM-2 missile variants have successfully intercepted targets 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 countermeasures environment. The SM-2 missile 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 missile family continues to grow internationally. Australia, Canada, Germany, Japan, Korea, the Netherlands, Spain and Taiwan have SM-2 capable ships. Australia’s Air Warfare Destroyer will employ SM-2, and several other navies are also defining requirements and ship configurations to support SM-2 applications.
