Raytheon wins $6.3 billion contract to produce Standard Missile-3 interceptors to bolster U.S. missile defense

RTX's Raytheon has secured a multi-year contract worth up to $6.3 billion to produce and maintain Standard Missile-3 Block IB (SM-3 IB) interceptors to replenish U.S. missile defense stocks after combat use. The agreement, announced Oct. 8, covers five years of work with an option to extend for two more. Production will take place primarily at Raytheon facilities in Tucson, Arizona, and Huntsville, Alabama. According to Reuters, recent conflicts in the Middle East have depleted missile defense inventories, increasing demand for interceptors and other air defense weapons.

The contract is also part of a U.S. push to boost weapons production capacity and replenish critical munitions.

SM-3 IB interceptor capabilities

The SM-3 IB is a ballistic missile defense interceptor designed to destroy short- to intermediate-range ballistic missiles in the midcourse phase of flight. Unlike systems designed to intercept lower-altitude threats, the SM-3 can engage targets outside Earth's atmosphere. It is part of the Patriot Ballistic Missile Defense System, which combines shipboard sensors, tracking and command systems, and interceptors launched from naval vessels. The SM-3 can also be operated from land-based Patriot shore-based facilities. The interceptor uses hit-to-kill technology, relying on a direct collision with an incoming missile's warhead rather than a traditional explosive warhead.

The Block IB variant features an improved two-color infrared seeker and upgraded guidance and propulsion capabilities to help steer the interceptor toward its target.

Raytheon said the SM-3 IB was first used in combat in 2024, when the U.S. Navy employed SM-3 interceptors in response to Iranian attacks on Israel. According to USNI News, the engagement marked the first combat use of the SM-3 family. The SM-3 family has several variants designed to meet different ballistic missile defense needs. The Block IB improves on the earlier Block IA with an upgraded seeker and enhanced divert and attitude control capabilities, helping the interceptor track and maneuver toward targets in the final stage of engagement.

The more advanced SM-3 Block IIA, co-developed by the United States and Japan, features a larger booster and a larger kinetic warhead to address more challenging ballistic missile threats.

New agreement context and other deals

The new agreement follows other major U.S. missile procurement deals as the Pentagon seeks to expand production and rebuild stocks. In October 2026, Raytheon also secured a Standard Missile-6 (SM-6) production contract worth up to $24.4 billion, while Lockheed Martin in July won a Patriot missile contract valued at $58.6 billion. Although the SM-3 IB and SM-6 belong to the same class of naval missiles, their roles differ. The SM-3 focuses on exoatmospheric ballistic missile interception, while the SM-6 supports a broader set of missions, including air defense and certain terminal ballistic missile engagements.

Raytheon President Phil Jasper said the SM-3 IB contract will help replenish stocks and sustain the defense capabilities needed by the U.S. Navy, the Missile Defense Agency, and their partners. The agreement's value of up to $6.3 billion means the announced ceiling should not be interpreted as guaranteed spending. Its five-year base period and two-year option provide a long-term framework for production and sustainment. Meanwhile, the actual pace of replenishment will depend on contract execution and production capacity.
