National Defense Authorization Act

The National Defense Authorization Act (NDAA) is a United States federal law specifying the budget and expenditures of the United States Department of Defense. Each year's act also includes other provisions. The U.S. Congress oversees the defense budget primarily through two yearly bills: the National Defense Authorization Act and defense appropriations bills. The authorization bill determines the agencies responsible for defense, establishes funding levels, and sets the policies under which money will be spent.
