S. 4784: National Defense Authorization Act for Fiscal Year 2027

S. 4784, the National Defense Authorization Act for Fiscal Year 2027, would set policy and authorize spending for Department of Defense programs and military construction, and for the national security programs of the Department of Energy. It would authorize buying items such as aircraft and ships, set the number of active duty and reserve personnel, and set policy on military health care and pay.

The bill would also set policy on defense acquisitions, cyber operations and artificial intelligence, and on the military's dealings with other countries. It would require the Defense Department to review materials including boron carbide, copper foil and synthetic diamond to protect access to critical defense components, and would let the department's Office of Strategic Capital make equity investments in non-federal entities working on batteries and critical minerals, materials and chemicals.
