L3Harris Secures $4.7 Billion PAC-3 MSE Propulsion Contract

L3Harris Technologies has received a $4.7 billion undefinitized contract from Lockheed Martin to produce solid rocket motor propulsion systems for the PAC-3 Missile Segment Enhancement interceptor. The agreement targets the defense manufacturing sector by expanding the production capacity of critical munitions and advanced air defense technologies.

Solid Rocket Motor Architecture and Interceptor Components
The PAC-3 Missile Segment Enhancement interceptor relies on advanced propulsion hardware to intercept tactical ballistic missiles and hostile aircraft. Under the seven-year contract, L3Harris will manufacture the primary two-pulse solid rocket motor, which provides the thrust necessary to expand the interceptor's engagement range and altitude. The production scope also includes the Lethality Enhancer and the Attitude Control Motors, which dictate the missile's maneuverability and hit-to-kill engagement precision. Ken Bedingfield, president of Missile Solutions at L3Harris, noted that the contract accelerates the expansion of propulsion production capacity to ensure that defense operators maintain the munitions required to deter evolving threats.

Manufacturing Infrastructure and Facility Expansion
To address production demands established by the Department of War framework agreement, L3Harris is scaling its solid rocket propulsion ecosystem. In June, the company initiated the construction of two new manufacturing facilities at its Camden, Arkansas site. Scheduled to become operational in 2027, these facilities are designed to increase onsite throughput and modernize the production of solid rocket motors. The infrastructure incorporates dedicated production bays and automated digital X-ray systems for component inspection. This expansion is part of a broader corporate investment that includes building approximately 60 new facilities and adding over one million square feet of manufacturing space across Alabama, Virginia, and Arkansas to support continuous munitions manufacturing.

The PAC-3 MSE interceptor utilizes an 11.4-inch diameter dual-pulse solid rocket motor. The propulsion architecture is engineered to deliver a rapid initial acceleration boost phase, followed by a delayed second pulse that maintains high velocity for long-range and high-altitude kinetic engagements. Each interceptor also incorporates 180 individual Attitude Control Motors to provide the rapid divert response required for direct body-to-body impact. Within the solid rocket motor supply chain for air defense interceptors, L3Harris serves as the primary manufacturer. However, to mitigate supply chain bottlenecks and increase annual production rates, Lockheed Martin and the defense sector have established qualification programs for secondary suppliers, such as Northrop Grumman. These competitors are independently developing compatible dual-pulse solid rocket motors that meet the precise thrust and dimensional requirements of the PAC-3 MSE airframe.
