Raytheon wins up to $6.3 billion multi-year contract for SM-3 Block IB interceptors

The Department of War and the Missile Defense Agency (MDA) have awarded Raytheon a multi-year contract worth up to $6.3 billion to build Standard Missile-3 Block IB interceptors. The department announced the award on 8 October. Its daily contracts notice said the contract was awarded on 7 October.

The contract has a base value of about $4.43 billion. Options lift the ceiling to about $6.34 billion. The MDA obligated about $454 million in fiscal 2026 procurement funds at the time of award. Raytheon will carry out the work in Tucson, Arizona, and Huntsville, Alabama. The notice gave an estimated completion date of 31 October 2034.

The award is an undefinitised contract action. This lets Raytheon start work while the final price and terms are settled. The contracts notice also described the award as noncompetitive.

The department's release said the agreement covers five years of production with two further option years. It said the contract would provide multi-year stability and direct capital to solid rocket motor suppliers and critical domestic sub-tier vendors.

What the SM-3 Block IB does

The SM-3 Block IB is a missile defence interceptor that can be fired from ships and from land sites. It is designed to destroy short- to intermediate-range ballistic missiles during the middle phase of their flight. The US Navy fields it alongside the larger and more capable SM-3 Block IIA.

The missile has already been used in combat. US Navy destroyers fired SM-3s for the first time against real targets during Iran's missile and drone attack on Israel on the night of 13 to 14 April 2024.

A reversal two years in the making

The award caps a reversal that unfolded between 2024 and 2026. In its fiscal 2025 budget request, released in March 2024, the MDA planned to end Block IB procurement. At a House Armed Services hearing on 1 May 2024, the then Navy Secretary, Carlos Del Toro, said the Navy would need more SM-3s and that the decision should be looked at again, The War Zone reported.

As a result, the line stayed open. In May 2025 the MDA awarded Raytheon an undefinitised contract worth up to $1 billion for as many as 55 Block IB rounds, Defense Archives reported.

In February 2026, Raytheon and the Department of War signed a framework agreement to accelerate Block IB production. The MDA told Defense Archives it planned to continue buying the missile. The outlet reported that Congress provided $475 million for Block IB in the fiscal 2026 appropriations act.

Second Raytheon interceptor award in a week

The SM-3 award follows a separate Navy contract worth up to $24.4 billion for Raytheon's SM-6 interceptor, announced on 1 October. That contract also covers five firm years with two option years.

Reuters reported that the Pentagon is trying to rebuild missile defence inventories depleted by conflicts in the Middle East. Operation Epic Fury, the US campaign against Iran that ran from 28 February to 5 May, and operations in the region since have placed heavy demands on Navy air defence. The USS Abraham Lincoln strike group alone shot down 77 one-way drones and destroyed 21 anti-ship cruise missiles while in the Middle East, according to Pentagon figures cited by USNI News.

What to watch

Navy ships in both the Middle East and the Pacific rely on Standard Missile interceptors. A steadier flow of SM-3s could ease pressure on Navy stocks over time, although the contract does not say when the first new rounds will be delivered.

Even so, funding is the bigger test. The department is operating under a continuing resolution that runs to 11 December. Breaking Defense counted more than 150 new programmes facing delay while it lasts.
