Signal Modernization Program

The Signal Modernization Program is a key procurement initiative within the Army's Other Procurement, Army (OPA) budget, specifically under the Communications and Electronics Equipment activity. Its overarching goal is to modernize and enhance the Army's signal and communications capabilities, ensuring that both active and reserve components are equipped to meet current and emerging operational requirements. The program is designed to support homeland defense missions, domestic emergency responses, and military support to civil authorities, as mandated by section 1815 of the FY 2008 National Defense Authorization Act (P.L. 110-181).

In FY 2025, the Signal Modernization Program underwent a significant consolidation, merging into the parent line item Tactical Network Communication and the sub-program Signal Modernization Program. This restructuring aims to streamline procurement efforts, improve resource allocation, and ensure a unified approach to upgrading tactical network communications across the Army. The consolidation reflects the Department of Defense's commitment to integrating signal modernization with broader tactical communication initiatives.

The program's specific objectives include the procurement of advanced communications equipment, such as modernized radios, networking hardware, and signal support systems. These assets are intended to replace legacy systems, enhance interoperability among units, and provide secure, resilient communications in contested environments. The modernization effort also supports the Army's transition to network-centric operations, enabling faster data exchange and improved situational awareness for commanders and soldiers at all echelons.

Within the FY 2025 budget, the Signal Modernization Program allocates resources to several Army components. The active Army receives the largest share, with a focus on equipping operational units for immediate deployment and mission readiness. The Army National Guard and Army Reserve also benefit from dedicated funding, ensuring that reserve forces maintain compatible communications capabilities for both federal and state missions. This distribution supports joint operations and enhances the Army's ability to respond to domestic emergencies and support civil authorities.

Procurement quantities and funding levels are detailed in the budget justification, with a total of 297 units planned for acquisition in FY 2025. The program's cost structure reflects investments in both equipment and initial spares, although specific unit costs and spares allocations are not disclosed in this summary. The focus remains on delivering reliable, scalable communications solutions that can be rapidly fielded and sustained across the force.

Justification for the program centers on its necessity for operational effectiveness and mission assurance. Modernized signal equipment is critical for maintaining secure communications, supporting command and control functions, and enabling rapid response to evolving threats. The program also addresses interoperability requirements with joint and coalition partners, ensuring that Army units can operate seamlessly in multi-domain environments.
