L3Harris Opens Camden Rocket Motor Plant Designed to Double GMLRS Motor Capacity

L3Harris Technologies has opened a new solid rocket motor production facility in Camden, Arkansas, that the company says is designed to double its current output of motors for the U.S. Army's Guided Multiple Launch Rocket System, or GMLRS. The plant, which L3Harris calls its Arsenal of Freedom facility, was opened on Oct. 20 with federal, state and local officials, including Under Secretary of War for Acquisition and Sustainment Michael P. Duffey and Arkansas Gov. Sarah Huckabee Sanders. The opening puts a long-planned piece of U.S. missile propulsion capacity into service at a time when the rocket motor supply base has become one of the tightest constraints on American munitions output.

How the program got here

GMLRS is a guided rocket built by Lockheed Martin and fired from the Army's M142 HIMARS and M270 launchers. L3Harris supplies the solid rocket motor that propels it, along with the electronic safe-and-arm device and the proximity sensor. The company, which acquired propulsion maker Aerojet Rocketdyne in 2023, says it has produced GMLRS propulsion units for decades and has already doubled GMLRS motor output in recent years.

The Camden expansion took shape under the 2023 Title III agreement, a federal tool used to fund domestic industrial capacity that the market alone has not supplied. L3Harris broke ground on four new solid rocket motor buildings in Camden in February 2025. At the time, it said the 60,000-square-foot structure would consolidate one key program under a single roof and cut the distance motors travel during manufacturing by 80%, with a dedicated mixer building and supporting propellant processing buildings alongside it. The building that opened this week is that consolidated GMLRS line.

Industry implications

Solid rocket motors sit underneath a wide range of tactical missiles, and the number of qualified U.S. suppliers is small. When motor output lags, it caps how quickly prime contractors can deliver finished rounds, regardless of how much assembly capacity they add elsewhere. A purpose-built line that doubles GMLRS motor capacity therefore addresses one of the more direct bottlenecks in the Army's precision fires inventory.

The timing also lines up with order flow. The $250 million Lockheed Martin follow-on award announced earlier this month gives the new building an immediate production assignment rather than leaving it to ramp on forecast demand. That sequence, with capacity coming online just as a record-quantity order is placed, reduces the risk that the facility sits underused in its first year.

Competitive and supply chain implications

For Lockheed Martin, which integrates GMLRS, a larger and more centralized motor supply should ease one of the inputs it does not control directly. Consolidating production under one roof also shortens internal logistics; the 80% reduction in motor travel distance that L3Harris cited when the project broke ground points to fewer handling steps between mixing, casting and final assembly, which can shorten cycle times for an energetic product that requires careful movement.

The Camden site is becoming a broader propulsion hub. L3Harris is also developing the Arkansas Advanced Propulsion Facilities campus there and two new buildings for PAC-3 propulsion production. In September, the company announced a seven-year, $4.7 billion undefinitized contract from Lockheed Martin for PAC-3 MSE interceptor propulsion, its largest PAC-3 propulsion award to date, and said both new Camden PAC-3 buildings are expected to be operational in 2027. Concentrating several motor lines in one location can spread fixed costs such as propellant processing and safety infrastructure, though it also concentrates exposure to any single-site disruption.

Upstream, higher motor rates will lift demand for propellant ingredients, motor cases, insulation materials and inspection equipment. L3Harris has said its Camden PAC-3 plant added automated digital X-ray equipment that cut inspection and cycle times, an example of where tooling suppliers stand to benefit as output rises.

Regional implications

Camden, in southern Arkansas, has long hosted rocket motor and munitions work, and the new facility deepens that base. The attendance of Gov. Sanders, Arkansas Secretary of Commerce Hugh McDonald, Sens. John Boozman and Tom Cotton, and Rep. Bruce Westerman reflects the state's interest in keeping defense manufacturing anchored there. The company did not disclose hiring figures for the new building.

The program also spreads work beyond Arkansas. The same Title III agreement funds new buildings in Orange County, Virginia, and equipment and digital upgrades in Huntsville, Alabama, while L3Harris's wider propulsion buildout includes sites in California. For allied operators of HIMARS and M270 launchers, more U.S. motor capacity is a precondition for faster GMLRS deliveries, since those buyers draw on the same production base as the Army.

What comes next

• Ramp of standard-range GMLRS motor production in Camden under the $250 million Lockheed Martin follow-on award.
• Completion of the remaining Title III projects in Orange County, Virginia, and Huntsville, Alabama.
• Definitization of the $4.7 billion PAC-3 MSE propulsion contract with Lockheed Martin.
• Startup of the two new Camden PAC-3 propulsion buildings, expected in 2027.
• Further progress on the Arkansas Advanced Propulsion Facilities campus and the company's wider buildout of roughly 60 facilities.
