CBO estimates that inflation-adjusted costs for the Department of Defense would climb from the $575 billion requested in 2018 to $688 billion in 2027 if DoD pursued goals that Administration officials have articulated for the military.
“This report describes CBO’s analysis of the costs and budgetary consequences through 2027 of the current Administration’s goals for increasing the readiness, size, and capabilities of the military. The report draws from the fiscal year 2018 budget request submitted by the Department of Defense (DoD) and from other official documents, including Congressional testimony presented by DoD officials. The 2018 budget request calls for $640 billion in funding for the department. Of that total, $575 billion would fund base-budget activities (such as day-to-day military and civilian operations and developing and procuring weapon systems) and $65 billion would fund overseas contingency operations (OCO, mostly for the conflicts in Afghanistan and in Iraq and Syria). The base-budget funding request is 3 percent more than the amount that would have been requested for 2018 under the Obama Administration’s final Future Years Defense Program, the 2017 FYDP, after adjusting for inflation.”
