ARNG HMMWV Modernization Program

The ARNG HMMWV Modernization Program is a procurement initiative within the Army's Other Procurement appropriation, specifically under Tactical and Support Vehicles. The program's primary objective is to modernize the Army National Guard's (ARNG) fleet of High Mobility Multipurpose Wheeled Vehicles (HMMWVs) by acquiring new production units. This modernization effort is designed to replace older, non-armor capable HMMWVs, thereby enhancing the safety, reliability, and operational capability of the ARNG's tactical vehicle inventory.

One of the central goals of the ARNG HMMWV Modernization Program is to support the Army Transformation Initiative. By divesting legacy HMMWVs that lack armor protection, the program aims to ensure that ARNG units are equipped with vehicles that meet current survivability standards. This is particularly important for missions involving homeland defense, domestic emergency response, and military support to civil authorities, as outlined in Section 1815 of the FY 2008 National Defense Authorization Act (P.L. 110-181).

For Fiscal Years 2024 and 2025, the program allocated funds for the procurement of HMMWVs. These vehicles are distributed to ARNG units to replace aging platforms and to ensure readiness for a wide range of operational scenarios, including disaster relief and contingency operations within the United States.

The modernization effort is justified by the need to maintain a capable and responsive National Guard force. Upgrading to newer HMMWVs with improved armor and reliability directly supports the ARNG's dual mission of federal and state service. The program does not include research and development activities; its focus is strictly on procurement of finished vehicles to meet immediate operational requirements.

Additionally, the program supports broader Department of Defense objectives by ensuring interoperability and standardization across active and reserve components. By procuring modern HMMWVs, the ARNG aligns its tactical vehicle fleet with the active Army, facilitating joint operations and logistics support. This procurement also addresses sustainment concerns by reducing maintenance costs associated with older vehicles and improving overall fleet readiness.

No funding is requested for FY 2026, indicating that the current phase of the program is concluding or transitioning to other modernization efforts. The absence of advance procurement and initial spares in the budget summary further underscores the program's focus on direct vehicle acquisition rather than long-term sustainment or incremental upgrades.
