L3Harris expands Tomahawk component manufacturing capacity

L3Harris Technologies and the US Navy’s Naval Air Warfare Center Weapons Division have signed a multi-year agreement to expand manufacturing capacity for critical missile components at China Lake, extending the current munitions-production push deeper into the Tomahawk supply chain.

The public-private arrangement is intended to address growing capacity requirements across several munitions programmes, with L3Harris specifically identifying Raytheon’s Tomahawk cruise missile among the weapons supported by the work. Neither the value of the agreement nor the additional production volumes and delivery schedule have been disclosed.

The distinction between component manufacture and complete missile production is important. Increasing output at a prime contractor’s final assembly line only creates additional weapons if propulsion, energetic, structural, electronic, guidance, and other specialist components arrive at compatible rates.

The China Lake agreement targets that lower level of the industrial chain. Naval Air Warfare Center Weapons Division maintains expertise and infrastructure around energetics as part of the Navy’s organic industrial base, while L3Harris brings an established commercial manufacturing role across missile propulsion and warhead systems.

L3Harris has supported Tomahawk production for more than 30 years. Its current programme contribution includes the Mk 135 solid-propellant booster and blast-fragmentation warhead, although the company has not provided a component-by-component breakdown of the work that will move through the new partnership.

The agreement should therefore not be read as establishing another Tomahawk final-assembly line, nor does the announcement state that China Lake will manufacture every L3Harris component already associated with the weapon. The verified development is a new manufacturing arrangement intended to increase critical component capacity for Tomahawk and other munitions.

Public-private production gives the Navy a route to combine government facilities and technical capability with an established industrial supplier. That can be particularly useful in energetics, where adding capacity involves more than installing conventional machine tools or leasing additional factory floor space.

Solid propellants, warheads, and related energetic components require specialist processing facilities, controlled materials, environmental systems, explosive-safety procedures, test infrastructure, trained personnel, and tightly governed production documentation. New capacity also has to demonstrate repeatable performance before it can become part of an accepted weapon-production stream.

The agreement arrives as Tomahawk manufacturing pressure is becoming visible at several supplier levels. Earlier this month, the Navy moved to accelerate Tactical Tomahawk warhead-housing production through an existing General Dynamics manufacturing contract, with additional housings required for both new-build and recertified missiles.

That action and the L3Harris agreement are separate procurements covering different suppliers and production activities. Together, however, they illustrate why a headline increase in complete-missile output has to be translated into corresponding capacity across multiple qualified manufacturing streams.

Raytheon secured a seven-year Tomahawk production contract in August supporting a substantial increase in annual output. Reaching higher rates requires more than expanding final assembly because the missile draws on propulsion units, warhead hardware, guidance and control electronics, structures, energetic materials, and specialist test equipment produced by a wider supplier network.

A shortage within one of those streams can constrain the complete weapon even when other suppliers have unused capacity. Missile programmes are particularly exposed to that problem where components rely on specialist energetic processes or facilities that cannot be expanded quickly without additional safety, environmental, qualification, and workforce measures.

The China Lake arrangement also reflects a broader US effort to make greater use of the government-owned industrial base alongside private manufacturers. Organic facilities can provide technical knowledge, specialist infrastructure, or available capacity that complements commercial production rather than replacing the prime and supplier network.

L3Harris has used the model elsewhere. The company previously established a public-private arrangement with Naval Surface Warfare Center Indian Head Division to increase output of Mk 104 solid dual-thrust rocket motors used in Raytheon’s Standard Missile family.

That experience provides a precedent for combining Navy energetics facilities with commercial production processes, although each missile programme brings its own tooling, materials, qualification, and acceptance requirements. Capacity created for one rocket motor cannot simply be reassigned to another without engineering and programme-specific work.

Long-running weapons such as Tomahawk introduce a further complication because the industrial base is supporting new production and the existing inventory at the same time. Recertification and upgrade work consume components, test capacity, engineering resources, and specialist labour that may also be needed for newly manufactured missiles.

The new agreement does not quantify how much additional Tomahawk output those manufacturing changes will support. Without a stated component rate or production timetable, it is not yet possible to compare the China Lake contribution directly with the wider missile-production targets.

The industrial direction is nevertheless clear. Tomahawk production growth is reaching beyond final assembly into component and energetic-material capacity, with the Navy using both existing suppliers and government facilities to reduce the risk that specialist processes become the limiting factor.

The next useful indicators will be production qualification, the specific component families assigned to China Lake, and measurable increases in accepted output. Those milestones will show whether the new public-private arrangement adds enough component capacity to keep pace with the much larger Tomahawk production programme now moving through the US missile industrial base.
