Another budget showdown this fall seems inevitable. The President’s Budget for Fiscal Year 2016 calls for $561 billion in defense spending (excluding overseas contingency operations). That’s $38 billion above sequestration levels.
Ultimately, however, budgeting is decided in Congress, and a look back at previous budget proposals shows that the president never gets exactly what he asks for. The chart below shows a five-year projection of Department of Defense (DoD) funding in each president’s budget proposal (the dashed line) compared with the actual funding levels passed by Congress (the solid black line).
President's Proposed DoD Budget vs. Actual
Differences between proposed and actual budgets have varied by president—especially during the last drawdown in defense spending in the late ‘80s and early ‘90s. As in the past, we should expect changes to this year’s proposed budget.
