The U.S. military budget is $824.1 billion. That's the budget for Fiscal Year 2018 which covers the period October 1, 2017 through September 30, 2018. Military spending is the second largest federal government expenditure, after Social Security at $1 trillion.  U.S. military spending is larger than the next nine countries combined

There are four components. First is the $574 billion base budget for the Department of Defense.

Second is the Overseas Contingency Operations for DoD to fight ISIS ($64.6 billion).

There's more to military spending than the Department of Defense. Many other agencies are involved with protecting our nation. These expenses are the third component, totaling $173.5 billion. They include the Department of Veterans Affairs ($78.9 billion), the State Department ($27.1 billion), Homeland Security ($44.1 billion), FBI and Cybersecurity in the Department of Justice ($9.5 billion) and the National Nuclear Security Administration in the Department of Energy ($13.9 billion).

The last component is $12 billion in OCO funds for the State Department and Homeland Security to fight ISIS. (Source: "Mid-Session Review Fiscal Year 2017, Table S-10." OMB, July 15, 2016.  "2018 Budget, Table 2," OMB, March 16, 2017.)

Defense Department Base Budget

DoD requested $598.9 billion. It seeks to:

  1. Continue retirement and TRICARE reforms. If you include subsidized housing, free healthcare, and the other benefits military personnel receive, the average compensation works out to $59,000 for enlisted personnel and more than $108,000 for officers. 
  1. Train local security forces in Iraq, Syria, and Afghanistan to combat ISIS.
  2. Expands the Navy and Air Force.
  3. Strengthen the Army and Marines. 
  4. Beef up cyber security forces. That include strengthening space control and investing advanced munitions systems.
  5. Reduce spending on headquarters by 25 percent. Improve audits, acquisition practices, and commissary spending. Eliminate excess infrastructure.

    The Air Force is moving forward with the F-35 Joint Strike Fighter program. The program will cost $400 billion for 2,457 planes. Most of the cost has been for development and testing.  (Source: "Watchdog: Delayed Testing Adds $1 Billion to F-35 Program," The Hill, April 24, 2017.)

    Lockheed Martin built 45 planes in 2015, costing $100 million each. That's expected to rise to 53 planes in 2016, and 160 annually by 2025. By then the jet should cost $85 million each, adjusted for inflation. The Air Force cut five F-35s in the FY 2017 budget. (Source: "FY 2018 Budget," OMB, March 16, 2017.

    Overseas Contingency Operations

    Ironically, the DoD base budget does not include the cost of wars. That falls under Overseas Contingency Operations. It's budgeted at $64.6 billion for DoD and $12 billion for the State Department.  For OCO spending back to 2001, see War on Terror Facts.  (Source: "2018 Budget, Table 2," OMB, March 16, 2017.)

    Factors Influencing Budget: 

    • 2003: Iraq War launched March 19.
    • 2004: U.S. torture at Abu Ghraib prison increased resistance, and costs.
    • 2005: Afghanistan War costs rose to protect free elections.
    • 2006: Costs rose in Iraq.
    • 2007: Surge in Iraq to counter violence.
    • 2008: Violence rose in Middle East due to recession.
    • 2009: Surge in Afghanistan.
    • 2010: Obama funds Iraq drawdown.
    • 2011: Iraq War ended but costs reached all-time high.
    • 2012: Troop withdrawal in Afghanistan War. Costs begin falling.
    • 2013: Sequestration cut spending.
    • 2014: Wind-down of Afghanistan War.
    • 2015: Sequestration cut spending. Still higher than in 2007.
    • 2016: Resurgence of ISIS drives spending higher.
    • 2017: Increase in VA and FBI funding. Trump asks Congress for additional $30 billion in military spending.
    • 2018: Trump asks to repeal sequestration for defense budget. Requests a spending increase to fight ISIS.

      DoD Tries to Save Money, But Congress Won't Let It

      The Defense Department knows it needs to become more efficient. It now spends a third of its budget on personnel and maintenance. That will rise to 100 percent by 2024, thanks to retirement and medical costs. That leaves no funds for procurement, research and development, construction or housing. These necessary support programs now take up more than a third of DoD's budget. (Source: "Pay Will Swallow DoD Budget by 2024," Center for Strategy and Budgetary Assessments, April 8, 2013.)

      How could the DoD become more efficient? First, it needs to reduce its civilian workforce, which grew by 100,000 in the last decade, instead of resorting to hiring freezes and unpaid furloughs. Second, it must reduce pay and benefits costs for each soldier. Instead, it plans to raise both.

      Third, and most important, it should close unneeded military bases. By its own estimates, the DoD is operating with 21 percent excess capacity in all its facilities. Unfortunately, Congress won't allow it to close bases. The Bi-Partisan Budget Act of 2013 blocked future military base closings. Few elected officials are willing to risk losing local jobs caused by base closures in their states. Instead, the Pentagon will need to reduce the number of soldiers so it can afford the benefits of bases. (Source: "Pentagon Lays Out Way to Slash Spending," The Wall Street Journal, August 1, 2013.)

      Congress is also reluctant to allow DoD to cut other costs, like military health benefits and the growth of military pay. It recently gave service members a 1 percent pay increase, but cut the cost-of-living-adjustment by 1 percent for veterans who retire before age 62. Fortunately, disabled veterans and surviving families had the cut re-instated. (Source: "House Quickly OKs Bipartisan Budget Deal," Stars and Stripes, December 12, 2013. "Disabled Veterans Get Back Pension Raises," CNN, January 14, 2014.)

      Sequestration cut defense spending by $487 billion over ten years. But many in Congressmen say the cuts jeopardize national security. They are concerned about a cutback of about 100,000 troops, closure of domestic military bases, and termination of some weapons systems.  All of those cuts cost jobs and revenue in their districts. That's why defense spending is usually an area that doesn’t get cut. (Source: "Lawmakers Skeptical of Cuts in 2013 Defense Budget," Reuters,  February 15, 2012.)
