Defense Budget

Spending for the Department of Defense (DoD) accounts for nearly all of the nation’s defense budget. The funding provided to DoD covers its base budget—which pays for the department’s normal activities—and its contingency operations in Afghanistan and elsewhere overseas. CBO analyzes the possible consequences of planned reductions in funding for the military’s force structure and acquisitions. The agency also studies the budgetary implications of DoD’s plans, including those for military personnel, weapon systems, and operations.
