      "summary": "The FY2021 President\u2019s budget request includes $753.5 billion in budget authority for national defense. National defense is one of 20 major functions used by the Office of Management and Budget (OMB) to aggregate budget dataand the largest in terms of discretionary spending. The national defense budget function (identified by the numerical notation 050) comprises three subfunctions: Department of Defense (DOD)\u2013Military (051); atomic energy defense activities primarily of the Department of Energy (053); and other defense-related activities (054), such as FBI counterintelligence activities.\nNational Defense (050) Budget Function\nThe $753.5 billion national defense request includes $740.5 billion in discretionary budget authority and $13.0 billion in mandatory budget authority, according to OMB. The request is $3.7 billion (0.5%) less than the FY2020-enacted amount of $757.2 billion. Adjusting for inflation, the FY2021 request is $738.8 billion in constant FY2020 dollars, $18.4 billion (-2.4%) less than the enacted FY2020 amount, according to a CRS analysis of OMB data.\nThe $740.5 billion requested for national defense discretionary funding includes\n$705.4 billion for DOD (95.3% of the total),\n$26.0 billion for atomic energy activities (3.5%), and\n$9.1 billion for other defense-related activities (1.2%).\nSee Figure 1.\nFigure 1. FY2021 National Defense (050) Budget Request\n(in billions of dollars of budget authority)\n/\nSource: OMB, Tables 24-1 and S-7.\nNotes: Totals may not sum due to rounding.\nHistorical Perspectives\nSince September 11, 2001, outlays for national defense discretionary programs, in nominal dollars (not adjusted for inflation), increased 130.3% to an estimated $704.8 billion in FY2020, according to data from OMB and the Congressional Budget Office (CBO). Over the same period, outlays for nondefense discretionary programs increased 104.3% to an estimated $700.9 billion in FY2020; meanwhile, outlays for mandatory programs (e.g., Social Security, Medicare, and Medicaid) increased 183.8% to an estimated $2.9 trillion in FY2020. Over the next decade, CBO projects mandatory spending and net interest payments on the national debt will increase faster than defense and nondefense discretionary spending. See Figure 2.\nFigure 2. Outlays by Budget Enforcement Category, FY2001-FY2030 (Projected)\n(in trillions of dollars)\n/\nSource: OMB, Table 8.1; and CBO, 10-Year Budget Projections, Tables 1-1 and 1-4.\nNotes: Figures from FY2001 through FY2019 from OMB; projections from FY2020 through FY2030 from CBO.\nOver the past half a century, discretionary defense outlays decreased as a share of total federal outlays (from 49.3% in FY1962 to an estimated 15.2% in FY2020) and Gross Domestic Product (from 9.0% in FY1962 to an estimated 3.2% in FY2020), according to OMB and CBO. See Figure 3.\nFigure 3. Defense Outlays as a Share of Total Outlays and Gross Domestic Product (GDP), FY1962-FY2030 (Projected)\n(in percentages)\n/\nSource: Figure 1 and OMB Table 10.1.\nNotes: See Figure 1.\nAligned with Budget Cap\nThe request conforms to the FY2021 discretionary defense spending limit (or cap) established by the Bipartisan Budget Act of 2019 (BBA 2019; P.L. 116-37). BBA 2019 raised the discretionary defense spending limit set by the Budget Control Act of 2011 (BCA; P.L. 112-25) to $671.5 billion for FY2021. BBA 2019 specified a nonbinding target of $69 billion in FY2021 for defense funding designated for Overseas Contingency Operations (OCO), which is effectively exempt from the caps.

The $69 billion in OCO funding includes\n$20.5 billion for direct war requirements (i.e., combat or combat support costs not expected to continue after the end of combat operations at major contingency locations);\n$32.5 billion for enduring requirements (i.e., enduring costs in theater and the continental United States [CONUS] expected to remain after the end of combat operations); and\n$16 billion for base requirements (i.e., funding for base budget requirements).\nFigure 4 depicts historical DOD funding by base and non-base budget funding.\nFigure 4.
