The Navy has ordered Raytheon Missiles and Defense to restart a shuttered production line for one of the launch systems that fires Tomahawk cruise missiles from submarine vertical launch tubes, according to a Department of War contract announcement published July 13, 2026. The not-to-exceed $101,976,000 order covers the non-recurring engineering needed to bring the MK 45 Capsule Launch System back into production after years of dormancy.
Background
The MK 45 Capsule Launch System is part of the Tomahawk Weapon System family, the hardware that houses a missile canister inside a submarine's vertical launch tubes and manages the sequence that ejects the weapon before its rocket motor ignites at the surface. Submarines carrying Tomahawk strike packages rely on capsule launch hardware like the MK 45 to translate a fire-control order into a missile leaving the tube cleanly, without damaging the boat or the surrounding tubes. Production lines for legacy submarine launch hardware have sat idle for extended periods as the Navy's shipbuilding and modernization dollars concentrated on new-construction Virginia-class and Columbia-class boats. That idle time creates a specific problem: components, vendors, and manufacturing processes that were qualified a decade or two ago no longer exist in the supply base. Restarting a line is rarely a matter of flipping a switch. It requires re-qualifying parts, finding new suppliers for components that original vendors no longer make, and in some cases redesigning subsystems around what is actually available today. That is the situation Raytheon Missiles and Defense now faces in Tucson, Arizona, where the new order tasks the company with getting the MK 45 line producing again to support what the contract describes as a limited production quantity of updated capsule launch systems for the Navy. Raytheon's Tucson site is best known for producing tactical missiles, but the facility also handles specialized launch and fire-control hardware under long-running Navy support agreements. The basic ordering agreement underpinning this action, N0001925G0009, gives the Navy a standing vehicle to issue task orders to Raytheon for this class of work without re-competing the agreement each time, which is why the MK 45 restart could move forward as a single order rather than a fresh procurement.Key Details
The Department of War's July 13 daily contracts announcement lists the award as order N0001926F0259, issued against basic ordering agreement N0001925G0009. It is structured as an undefinitized cost-plus-fixed-fee order with a not-to-exceed value of $101,976,000, meaning Raytheon can begin work immediately while the government and the company continue negotiating the final definitized price. The scope covers non-recurring engineering tied to restarting MK 45 production, and the Department of War's listing spells out four specific work streams:- Obsolescence mitigation — identifying and re-qualifying parts and suppliers for components that are no longer available from original sources
- Design, development, fabrication, integration, inspection, and testing work needed to stand the line back up
- Updates to the system's technical data package, the engineering documentation that defines how the hardware is built and maintained
- Redesign of the Eject Initiation Subsystems, the components responsible for triggering a missile's departure from its launch capsule
