# Boeing Expands Huntsville PAC-3 Seeker Production

Boeing received an approximately **$14.7 billion, seven-year undefinitized contract action** from Lockheed Martin to triple production of PAC-3 Missile Segment Enhancement (MSE) seekers, a key component of Patriot interceptors. The agreement formalizes a production framework with the U.S. Department of Defense, and Boeing’s manufacturing ramp-up and hiring in Huntsville, Alabama, began in 2026. Because the action remains undefinitized, final terms, quantities, and pricing are not yet settled; the award is not itself an open solicitation for suppliers.

- Suppliers may find opportunities in Boeing’s expanded seeker-production supply chain, but should pursue them through Boeing or Lockheed Martin rather than treat the announcement as an open bid.
- The scale-up signals sustained demand for missile-defense components and manufacturing capacity; companies should assess whether their capabilities align with Boeing’s supplier-development and production needs.
- Contractors’ investment decisions may depend on finalized contract terms and funding availability. The signals identify no supplier solicitation, procurement contact, or proposal deadline.
