Department of Defense Appropriations Act, 2026

This bill, H.R. 4016, is an appropriations measure for the Department of Defense (DoD) for the fiscal year ending September 30, 2026. It authorizes funding across three main titles: Military Personnel (Title I), Operation and Maintenance (Title II), and Procurement (Title III), plus a number of DoD-wide accounts and programs. In broad terms, it provides the pay and benefits for active-duty and reserve service members, funds day-to-day military operations and maintenance, and finances the purchase and modernization of weapons, aircraft, ships, and related defense capabilities. The bill also contains numerous policy provisions and account-level authorities—such as transfer flexibilities, special funds (e.g., Counter-ISIS Train and Equip Fund), and reporting requirements—designed to support DoD priority programs, force readiness, and ongoing modernization, including major shipbuilding and missile programs. As introduced and marked up, the bill includes substantial funding levels for each service and major accounts, and it includes a variety of transfer authorities and conditionals that affect how money can be reallocated within the DoD. It also includes several targeted programs and safeguards, such as funding for APEX Accelerators, limits on certain interagency consolidations, oversight requirements for classified activities and risk reduction related to National Security Systems, and the Counter-ISIS Train and Equip Fund with vetting and reporting requirements.
