Department of Defense Appropriations Act 2026 funds military pay, training, health care, weapons, ships, aircraft, cyber work, and cleanup. It boosts aid for allies and partners such as Taiwan, Israel, Jordan, and anti-ISIS forces. It also blocks funding for some COVID vaccine and mask rules, DEI and critical race theory programs, gender-affirming care, and some detainee transfers, while adding more reporting, oversight, and Buy American rules.
