US signs 7-year deals with L3Harris, Lockheed to boost PAC-3 MSE and THAAD output
Synopsis
The US Department of War has locked in seven-year supply agreements with L3Harris and Lockheed Martin to scale production of PAC-3 MSE and THAAD interceptor components — a deliberate push to place the American defence industrial base on a wartime production footing, with no financial figures disclosed.

The US Department of War has signed two seven-year framework agreements with L3Harris and Lockheed Martin to expand production capacity for critical components used in the PAC-3 MSE interceptor and the Terminal High Altitude Area Defense (THAAD) missile defence system, the department announced on 28 July. The agreements are designed to accelerate the manufacture of propulsion and control systems that enable interceptors to detect and destroy ballistic and cruise missile threats.
What the Agreements Cover
The first agreement focuses on the PAC-3 Missile Segment Enhancement (MSE) system. Under its terms, L3Harris will ramp up production of its advanced two-pulse solid rocket motor, Attitude Control Motors, and Lethality Enhancer — components that give the PAC-3 MSE the speed, range, and manoeuvrability required to intercept advanced tactical ballistic missiles, cruise missiles, and enemy aircraft.
The second agreement addresses propulsion for the THAAD interceptor and was jointly signed by the department, L3Harris, and Lockheed Martin. It covers two critical components: the solid rocket boost motor that launches the interceptor, and the Liquid Divert and Attitude Control System (LDACS), which provides in-flight manoeuvrability enabling the interceptor to engage ballistic missile threats both inside and outside the Earth's atmosphere.
What the Government Said
Michael P. Duffey, Under Secretary of War for Acquisition and Sustainment, framed the move as a strategic imperative. 'Rebuilding the Arsenal of Freedom requires moving with speed and precision to scale the production of critical munitions,' he said. He added that the agreements with L3Harris represent 'a decisive win for the Warfighter, underscoring our commitment to sending clear demand signals to the entire supply chain.'
Financial Terms and Production Targets
The department did not disclose the financial value of either agreement, nor did it set specific annual production targets. Officials described both deals as part of a broader effort to provide defence manufacturers and their suppliers with stable, long-term demand signals — a deliberate shift intended to reduce procurement uncertainty across the defence industrial base.
Broader Strategic Context
The agreements are a direct outcome of the department's Acquisition Transformation Strategy, an initiative aimed at cutting bureaucratic delays and enabling officials to work directly with suppliers at every tier of the defence supply chain. The strategy is explicitly designed to place the US defence acquisition system on what officials describe as a 'wartime footing.' Notably, the latest deals follow a series of earlier PAC-3 MSE framework agreements with prime contractor Lockheed Martin, seeker manufacturer Boeing, and multi-component supplier Honeywell, suggesting a systematic effort to lock in supply chain commitments across the entire Patriot ecosystem.
The PAC-3 MSE is the most advanced interceptor variant within the Patriot air and missile defence system, engineered to destroy incoming threats through direct kinetic impact. With demand for air defence systems surging globally — particularly in the context of ongoing conflicts — the long-term agreements are also seen as a signal to allied nations procuring US missile defence platforms that supply chains are being reinforced.
Point of View
Not delivery contracts, and their primary purpose may be as much political as operational: assuring allied buyers and domestic suppliers that the US is serious about restoring munitions depth. The systematic sequencing of deals across Lockheed, Boeing, Honeywell, and now L3Harris suggests a deliberate effort to de-risk the entire Patriot supply chain rather than fix a single bottleneck. Whether the Acquisition Transformation Strategy actually cuts timelines — or merely rebrands existing procurement pathways — will be the real test of this initiative.

Frequently Asked Questions
What are the US Department of War's new agreements with L3Harris and Lockheed Martin?
The US Department of War has signed two seven-year framework agreements to expand production of critical components for the PAC-3 MSE interceptor and the THAAD missile defence system. The deals cover propulsion and control systems and are intended to provide long-term, stable demand signals to defence manufacturers and their suppliers.
What components will be produced under the PAC-3 MSE agreement?
Under the PAC-3 MSE agreement, L3Harris will scale up production of its two-pulse solid rocket motor, Attitude Control Motors, and Lethality Enhancer. These components give the PAC-3 MSE the speed, range, and manoeuvrability needed to intercept ballistic missiles, cruise missiles, and aircraft.
What is the LDACS and why does it matter for THAAD?
The Liquid Divert and Attitude Control System (LDACS) provides the THAAD interceptor with in-flight manoeuvrability, enabling it to engage ballistic missile threats both inside and outside the Earth's atmosphere. It is one of two critical components covered under the new THAAD propulsion agreement.
How much are the agreements worth and what are the production targets?
The US Department of War did not disclose the financial value of either agreement and set no specific annual production targets. The deals are described as long-term demand commitments designed to build a more robust and resilient defence production base.
How do these deals fit into the broader US defence acquisition strategy?
The agreements are a direct result of the Acquisition Transformation Strategy, which aims to reduce bureaucratic delays and allow officials to engage suppliers at every level of the defence industrial base. The strategy is intended to place US defence acquisition on a wartime footing, and follows earlier framework deals with Lockheed Martin, Boeing, and Honeywell for PAC-3 MSE components.
