Department of Defense Appropriations Act, 2026

This bill is the Senate’s ongoing annual appropriation for the Department of Defense (DoD) for the fiscal year ending September 30, 2026. It provides funding across all major DoD accounts—Military Personnel, Operations and Maintenance, Procurement, Research, Development, Test and Evaluation (RDT&E), and Defense Health—covering the Army, Navy, Marine Corps, Air Force, Space Force, and their reserve components, plus Defense-wide agencies and programs. In addition to traditional line items for pay, readiness, and modernization, the bill makes sizable investments in major platforms (such as Navy submarines and aircraft, and Air Force space and missile systems), and includes specialized programs like the Counter-Islamic State (ISIS) Train and Equip Fund and Defense-related security cooperation initiatives. The bill also contains numerous policy and oversight provisions, such as reporting and vetting requirements for counterterrorism assistance, limitations on consolidating legislative liaison offices, and targeted spending authorities (e.g., for environmental restoration and the Defense Production Act). The bill is introduced and reported by the Senate Committee on Appropriations and has not yet become law. In short, the bill would fund current DoD operations and modernization with a strong emphasis on shipbuilding and major weapons programs, while also funding health care for service members and several security-cooperation and emergency-response activities overseas. It includes guardrails and reporting requirements intended to ensure congressional oversight and accountability for sensitive programs and foreign assistance.
