SM-3 Block IB: Raytheon’s $6.3B Deal to Restock Interceptors
The Missile Defense Agency awarded Raytheon up to $6.3B for SM-3 Block IB interceptors. Only $454M is committed so far, and no missile count is public.
On 7 October the Missile Defense Agency awarded Raytheon a contract worth up to $6,342,404,516 to build Standard Missile-3 Block IB interceptors, the Department of War said in its daily contracts list. The company described it as a five-year deal with two option years, valued at up to $6.3 billion, for the ship- and land-based missile that shoots down ballistic missiles in space.
The headline number is a ceiling, not a purchase order. The money actually committed so far is a small share of it, and no one has said how many interceptors it buys.

“Undefinitized” means work can begin before the final price and terms are agreed, WeaponSpecs explains. By our arithmetic, the $454.2 million obligated is about 10 percent of the base value and about 7 percent of the total with options.
The missile
SM-3 Block IB belongs to a family of “hit-to-kill” interceptors that destroy incoming warheads by collision, not by explosion, Defense News reports. It is meant for short- and intermediate-range ballistic missiles, which it engages at roughly the midpoint of their flight. Defense News says it tracks targets with a two-color infrared seeker and steers with short bursts from its own thrusters.
The U.S. Navy first used it in combat in 2024, when the destroyers USS Arleigh Burke and USS Carney fired SM-3s at Iranian missiles aimed at targets in Israel, according to Defense News. In April, the Center for Strategic and International Studies named it one of seven “critical munitions” facing shortages, alongside Patriot, Precision Strike Missile, THAAD and Tomahawk.
One of a string of Raytheon deals
Breaking Defense says the award follows a February framework agreement between the Pentagon and Raytheon, and sits beside several recent deals with the same company. Defense News adds that SM-3 Block IB was one of five framework agreements Raytheon signed that month. The outlet lists a $24.4 billion contract for Standard Missile-6, a $22.9 billion Tomahawk contract meant to lift output to 1,000 rounds a year, and an AMRAAM deal worth nearly $20.7 billion.
“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,” Under Secretary of Defense for Acquisition and Sustainment Michael Duffey said in a Pentagon release, as quoted by Breaking Defense. Raytheon’s release says the award “supports urgent replenishment of missile defense inventory that has been successfully used in combat.”
Why it matters
Peter’s World analysis, based on the sources cited in this article.
Interceptors are consumed when they work. Defense News reports that analysts warned in March that heavy interceptor use in the war with Iran could strain U.S. defenses if the fighting drags on. A five-year production commitment tells suppliers to plan for sustained demand, which is the rationale the Navy gave for its SM-6 award.
A single noncompetitive source also concentrates risk. Every SM-3 Block IB in this contract comes from Raytheon’s Tucson and Huntsville sites, so a plant disruption or a shortage of sub-tier parts would reach the whole line. The Pentagon’s own language about breaking sub-tier bottlenecks points to that weak spot.
Until the price is definitized and the number of missiles is published, the public cannot judge how fast stocks will recover. The $454.2 million already obligated is the firm commitment; the rest is a ceiling.
What to watch: the definitized price and terms, whether the Missile Defense Agency exercises the options, a published missile quantity or delivery schedule, and fiscal 2027 funding.
