The U.S. Department of War and the Missile Defense Agency (MDA) have awarded RTX’s Raytheon a multi-year contract worth up to $6.3 billion for the production and sustainment of Standard Missile-3 Block IB (SM-3 Block IB) interceptors.

The five-year agreement includes two additional option years and supports efforts to replenish U.S. ballistic missile defense inventories while expanding manufacturing capacity.

Raytheon will carry out most of the work at its facilities in Tucson, Arizona, and Huntsville, Alabama. The contract is being issued as an undefinitized contract action, allowing work to begin while the government and company finalize certain terms.

The U.S. Department of War statement does not specify the number of interceptors covered by the award or provide a delivery schedule.

Under Secretary of War for Acquisition and Sustainment Michael P. Duffey said, “Our warfighters must never face a fair fight, and the SM-3 Blk IB has proven its operational superiority to dominate any adversary across the globe.”

“This contract provides production certainty to our defense industrial base, breaks sub-tier manufacturing bottlenecks, and ensures that our fleets and combatant commands have the interceptors required to dominate the battle space — air, sea or land,” he added.

The investment in assembly lines, solid-rocket motor suppliers, and other domestic vendors is part of the effort to increase manufacturing capacity.

The contract follows earlier agreements between Raytheon and the Department of War to expand production of several major weapons systems. The new award establishes a longer-term procurement framework for the SM-3 Block IB, although the pace of additional deliveries will depend on manufacturing capacity and the availability of critical components.

SM-3 Block IB Interceptor

The SM-3 Block IB is designed to intercept short- to intermediate-range ballistic missiles during the midcourse phase of flight, when they travel outside Earth’s atmosphere. It operates as part of the Aegis Ballistic Missile Defense system and can be launched from equipped U.S. Navy cruisers and destroyers, as well as land-based Aegis Ashore installations.

The interceptor uses hit-to-kill technology, destroying its target through the force of a direct collision. Its kinetic warhead carries an infrared seeker and guidance and control systems that allow it to acquire, track, and maneuver toward an incoming ballistic missile warhead. The interceptor does not rely on a conventional explosive warhead to destroy its target.

The Block IB variant introduced several improvements over the earlier Block IA, including a two-color infrared seeker, an advanced signal processor, and an improved divert and attitude control system. These upgrades improve target discrimination and allow the kinetic warhead to adjust its course during the engagement.

The SM-3 Block IB also forms part of a wider missile defense architecture that uses different interceptors against threats at different stages of flight. Its exo-atmospheric interception role differs from that of terminal defense systems such as the Patriot PAC-3, which is designed to engage threats closer to the defended area.

The more advanced SM-3 Block IIA was developed through cooperation between the United States and Japan. It features larger rocket motors and an enhanced kinetic warhead, providing greater capability against ballistic missile threats. Both variants operate within the Aegis missile defense framework, but their performance characteristics and engagement capabilities differ.

Combat Use

The SM-3 Block IB was first used in combat in April 2024, when U.S. Navy forces launched interceptors against Iranian ballistic missiles headed toward Israel. The engagement took place during a large-scale Iranian attack involving numerous ballistic missiles and other weapons.

The combat use demonstrated the role of ship-based missile defense in responding to ballistic missile attacks. Aegis-equipped ships can deploy to different maritime regions and use their sensors and interceptors to engage incoming threats, provided the systems have suitable tracking data and an opportunity to conduct an engagement.

Such operations also place demands on available interceptor stocks. Advanced missile defense weapons involve specialized components and complex manufacturing processes, and replacing weapons expended during combat requires continued production and deliveries. The time needed to manufacture additional interceptors makes procurement planning an important part of maintaining operational readiness.

The SM-3 operates alongside other U.S. air and missile defense systems, each designed to address particular types of threats. The Missile Defense Agency’s description of Aegis Ballistic Missile Defense outlines the system’s role in engaging ballistic missiles during the midcourse phase and coordinating with other elements of the wider missile defense network.

Pentagon Expands Missile Production

The latest award comes as the Department of War seeks to increase output across several weapons programs and strengthen the industrial base supporting U.S. forces. Long-term procurement agreements can give manufacturers greater confidence when investing in facilities, equipment, and workforce expansion, while helping suppliers plan for sustained demand.

In February 2026, Raytheon announced five framework agreements with the Department of War covering the Tomahawk cruise missile, AMRAAM, SM-3 Block IB, SM-3 Block IIA, and SM-6. The agreements were intended to expand production capacity and accelerate deliveries of these weapons.

Raytheon said it would increase annual production of Tomahawk missiles to more than 1,000, AMRAAMs to at least 1,900, and SM-6 missiles to more than 500, while accelerating SM-3 Block IB production.

The SM-3 supply chain depends on specialized components, including solid-rocket motors, guidance systems, and kinetic warhead technology. If suppliers cannot deliver these components at the required rate, increased final assembly capacity alone will not be enough to raise deliveries. The contract’s emphasis on supplier investment reflects the need to maintain production across the entire manufacturing chain.

The $6.3 billion figure represents the maximum value of the new agreement, including its potential scope over the procurement period and options. It does not establish the number of interceptors that will be delivered or confirm that the full amount will be spent. Those details will depend on the finalized contract terms and subsequent procurement decisions.

The agreement gives Raytheon and its suppliers a longer planning horizon for the SM-3 Block IB program. The number of additional interceptors delivered, and the speed at which production increases, will depend on the company’s manufacturing output and the capacity of its suppliers to meet demand.
