L3Harris Opens Arkansas GMLRS Motor Plant as Lockheed Martin Awards $250M Follow-On

L3Harris has opened its Arsenal of Freedom plant in Camden, Arkansas, to manufacture solid-fuel rocket motors for Guided Multiple Launch Rocket System (GMLRS) rockets used by the U.S. Army’s M142 HIMARS and M270 MLRS platforms. The facility is designed to double existing production capacity and allow for further expansion. Its opening aligns with broader efforts to increase the defense industrial base’s ability to supply rocket propulsion as U.S. and allied demand grows. L3Harris described the investment as an important step in strengthening production of solid-fuel rocket engines “which our country and its allies urgently need.”

The new plant is associated with a separate $250 million follow-on contract awarded to L3Harris by Lockheed Martin for a record quantity of standard-range GMLRS propulsion units. The distinction in award source is important for procurement analysis: the $250 million award is from Lockheed Martin, not a direct U.S. government contract. The facility expansion also builds on a $216 million cooperation agreement L3Harris signed with the Pentagon in 2023. These are related elements of the program’s production history, but they should not be conflated as a single government award or as evidence of a currently open solicitation.

For contractors and suppliers, the development points to continued demand and production scaling across the GMLRS propulsion supply chain. L3Harris has produced GMLRS propulsion units for decades and also supplies the system’s electronic safe-and-arm device and proximity sensors. The source reports that the company has doubled GMLRS solid rocket motor output in recent years through advanced manufacturing techniques and processes. The new facility is described as a 60,000-square-foot operation, with production to be centralized and supported by automation and robotics designed to streamline manufacturing stages. The expansion is therefore relevant not only to motor production but also to firms assessing adjacent manufacturing, automation, materials, and production-support capabilities.

L3Harris is also pursuing other Arkansas production investments, including the Arkansas Advanced Propulsion Facilities complex and two new facilities to support production of PAC-3 rocket engines. These projects indicate a broader concentration of propulsion manufacturing activity in the state. For market participants, the practical takeaway is to monitor program demand, facility ramp-up, and potential supply-chain needs while distinguishing confirmed awards from future opportunities. No current solicitation is identified in the source material, so this signal supports competitive intelligence and partner outreach rather than immediate bid action. Scott Alexander, president of Propulsion Systems, Missile Solutions at L3Harris, said the record-quantity follow-on award “demonstrates confidence in L3Harris’ missile propulsion expertise and our ability to deliver at scale.”
