RTXs Raytheon SM-3 Block IIA

Raytheon, an RTX business, has entered full-rate production for Standard Missile-3 Block IIA, validating the program's design maturity amid increased demand for the product from the United States and allied partners.

The SM-3 Block IIA production milestone cleared the way for a $1.9 billion award from the U.S. Missile Defense Agency in July 2024 to produce rounds for both the U.S. government and Japan’s Ministry of Defense.

Full-rate production signals that there is no elevated design or manufacturing risk in the missile and validates its reliability and performance.

"SM-3 Block IIA is a testament to the continuing partnership with Japanese industry to mature ballistic missile defence capabilities for the defence of our nation and our allies around the globe," said Barbara Borgonovi, president of Naval Power at Raytheon. "This milestone indicates that the team has achieved full maturity in the missile's design, which leads to greater efficiencies throughout the program."

SM-3 Block IIA, created in a landmark cooperative development program between MDA, Japan Ministry of Defense and their industry partners (Raytheon and Japanese industry), is the first MDA-procured program of its kind to achieve this manufacturing milestone. SM-3 Block IIA features larger rocket motors, and an enhanced kinetic warhead compared to its predecessors, allowing it to engage threats faster and protect larger regions from short- to intermediate-range ballistic missile threats.

Work under this contract will be done at Raytheon facilities in Tucson, Ariz., and Huntsville, Ala., with completion by February 2031.
