CAMDEN, Arkansas — L3Harris Technologies (NYSE: LHX) has secured a $250 million follow-on contract from prime contractor Lockheed Martin to manufacture solid rocket motors for the standard-range Guided Multiple Launch Rocket System (GMLRS). The award represents the largest single-order quantity of GMLRS propulsion units in the program’s history.
Production will be centralized at L3Harris’ new 60,000-square-foot “Arsenal of Freedom” facility in Camden, Arkansas, constructed via a Defense Production Act Title III cooperative agreement. The automated manufacturing plant—opening in late 2026—utilizes advanced process controls, robotics, and autonomous mobile transport systems to reduce motor travel distances by 80% and scale baseline output. Beyond rocket motors, L3Harris supplies critical flight-safety components for the GMLRS rocket architecture, including electronic safe-and-arm devices (ESAD) and proximity fuzes.
