The U.S. Department of Defense has awarded Raytheon a $258 million contract for the development of the Standard Missile 2 (SM-2) Block IIICU All Up Round. The agreement includes options that, if exercised, could raise the total value to $263 million.

According to the Department of Defense, about 72% of the work will take place at Raytheon’s facilities in Tucson, Arizona. Additional production will occur in Simsbury, Connecticut (7%), Wolverhampton, United Kingdom (3%), Salt Lake City, Utah (3%), and other U.S. locations in smaller portions.

The SM-2 Block IIICU development program aims to enhance existing capabilities to meet evolving threat environments. Advances in missile guidance, propulsion, and warhead technology are expected to improve interception rates and expand operational flexibility.

For the U.S. Navy, the SM-2 continues to serve as a critical component of surface combatant defense. Its integration into Aegis-equipped ships ensures coordinated defense operations, particularly in high-threat regions.

SM-2 Missile

Raytheon describes the SM-2 missile as “the world’s premier surface-to-air defense weapon.” It is a primary anti-air warfare system for the U.S. Navy, capable of defending against anti-ship missiles and aircraft at ranges up to 90 nautical miles and altitudes up to 65,000 feet.

The missile plays a central role in a ship’s layered defense system, protecting against high-speed, highly maneuverable threats. It can be launched from the MK-41 Vertical Launcher System (VLS) and the MK-57 Advanced VLS. The weapon is expected to remain a core component of U.S. Navy Aegis destroyers and cruisers for decades.

Technical capabilities

The SM-2 is equipped with radar-seeker technologies in continuous wave and interrupted continuous wave guidance modes, tail control systems, and solid rocket motor propulsion. These features enable the missile to engage high-speed, maneuvering targets, supported by updated radar targeting and directional warheads.

Raytheon states that the SM-2 offers both medium- and long-range engagement capabilities, with flexibility against a variety of airborne threats. Its design allows for integration into multiple naval platforms, supporting joint and allied maritime operations.

More than 12,000 SM-2 missiles have been delivered to the U.S. military and allied forces. Current international operators include Australia, Canada, Germany, Japan, South Korea, the Netherlands, Spain, and Taiwan. Chile and Denmark are the newest countries to add the SM-2 to their arsenals.

The SM-2 has been involved in numerous live-fire exercises and operational deployments. In 2020, Raytheon and the U.S. Navy successfully flight-tested the first SM-2 from the restarted production line. The missile was launched, flew as planned, and transmitted accurate telemetry data to the range while engaging an airborne Navy target.

The missile has a long-standing record of operational testing, with over 2,800 successful flight tests. The U.S. Navy reports that the system has consistently demonstrated its effectiveness in intercepting a wide range of airborne threats.

In early 2024, the U.S. Navy confirmed it used SM-2 missiles in the Red Sea to intercept anti-ship missiles and drones launched by Houthi rebels. These attacks targeted commercial shipping transiting the waterway. The Navy credited the SM-2 with contributing to the defense of vessels in a contested maritime environment.

International cooperation

The SM-2 program has been supported through foreign military sales to allied nations. This cooperation strengthens interoperability between U.S. naval forces and partner fleets, enabling coordinated responses to shared security challenges.

Countries operating the SM-2 benefit from U.S. Navy training programs, technology updates, and maintenance support. These partnerships contribute to a common maritime security framework, particularly in regions facing anti-ship missile proliferation.

Raytheon’s contract for the SM-2 Block IIICU reflects ongoing investment in layered missile defense systems. As adversary capabilities evolve, the missile’s modernization aims to address emerging threats such as supersonic and potentially hypersonic projectiles.

With decades of operational experience, a strong production base, and continued U.S. and allied adoption, the SM-2 is positioned to remain a core element of naval air defense strategy. The current development program reinforces its role in defending both national and international maritime interests.
