Tomahawk Mods

The Tomahawk Mods program, as outlined in Navy Budget Line Item 2301, is focused on the modernization, recertification, and capability enhancement of the Navy's Tactical Tomahawk (TACTOM) cruise missile inventory. The primary goals are to extend the service life of existing missiles, ensure compliance with evolving operational requirements, and introduce new capabilities to address emerging threats. The program is managed by the U.S. Navy, with Raytheon serving as the primary contractor for manufacturing and integration activities.

Recertification TACTOM BLK V is a core objective of this line item, involving the mid-life recertification of RGM109E and UGM109E Block IV Tomahawk missiles. This process extends the missiles' total service life to 30 years by performing a comprehensive overhaul at the 15-year mark. Recertification includes inspection, refurbishment, and replacement of critical components, ensuring continued reliability and effectiveness. The budget supports the recertification of Block V missiles, with funding allocated for labor, component recertification, and associated support costs.

NAV/COMMs Modernization is another significant element, aimed at upgrading the Tomahawk's navigation and communication systems. This subprogram replaces obsolete Satellite Data Link Terminal (SDLT) hardware and UHF DAMA communications infrastructure with the Integrated Single Box Solution (ISBS) radio, new antennas, and updated cabling. The modernization ensures continued secure and reliable communications, enhances in-flight retargeting, and supports rapid mission planning. Funding is provided for NAV/COMMs kits to be installed during the recertification process.

Maritime Strike Tomahawk (MST) introduces a new seeker and supporting hardware to enable the Tomahawk to engage moving maritime targets, expanding its mission set beyond land attack. The MST upgrade includes advanced sensors, processors, and integration of a new nosecone and power supply. Funding is provided for MST kits, which will be installed in recertified missiles, and addresses prior year cost overruns related to troubleshooting and rework of processor and sensor assemblies.

M-Code GPS User Equipment is a compliance-driven upgrade to ensure the Tomahawk meets Public Law 111-38, Section 913, by integrating next-generation, anti-jam GPS receivers. The M-Code kits enhance the missile's resilience to electronic warfare and GPS denial, supporting secure and precise navigation in contested environments. Production of these kits is scheduled to begin following completion of hardware and software development.

Joint Multiple Effects Warhead System (JMEWS) is a warhead modernization initiative that equips the Tomahawk Block V with a new warhead capable of defeating a broader range of land targets. JMEWS combines blast, fragmentation, and penetration effects, and is designed to meet Insensitive Munitions requirements for improved safety during storage and transport. Funding supports procurement of long-lead materials for future JMEWS kit production, with installation planned during subsequent recertification cycles.

In addition to these major subprograms, the Tomahawk Mods line item includes funding for production support, support equipment (including classified elements), integrated logistics support, and MK-45 submarine capsule recertification. These activities ensure the sustainment and operational readiness of the Tomahawk fleet. The request reflects a combination of discretionary and mandatory funding, with adjustments made to promote efficiency and align with government-wide cost-saving initiatives.
