The foreward of the 2009 National Defense Authorization Act states,
"H.R. 5658 would authorize appropriations totaling $602 billion for fiscal year 2009 for the military functions of the Department of Defense (DoD), for certain activities of the Department of Energy (DOE), and for other purposes. That total includes $70 billion for military operations in Iraq and Afghanistan. The bill also would authorize $1.6 billion in 2008 supplemental appropriations, primarily for military construction projects. In addition, H.R. 5658 would prescribe personnel strengths for each active-duty and selected reserve component of the U.S. armed forces. CBO estimates that appropriation of the authorized amounts would result in additional outlays of $596 billion over the 2008-2013 period.
Including outlays from funds previously appropriated, spending for defense programs authorized by the bill would total about $600 billion in 2009, CBO estimates. That figure, however, excludes outlays from the likely enactment of supplemental appropriations for 2008 that are not authorized by the bill. Including the effects of those additional supplemental appropriations for 2008 now being considered by the Congress, spending in 2009 would total more than $630 billion."
