Weapon Systems

Funding for weapons systems—which constitutes about one-quarter of the Department of Defense’s budget—is used to procure new systems, upgrade existing systems, and perform research, development, testing, and evaluation of new systems. CBO reviews selected weapon programs and provides a regular analysis of the long-term cost of planned weapons acquisition.

    The Department of Defense’s five-year plan calls for budgets averaging $534 billion (in 2016 dollars) from 2016 through 2020, but they would average $565 billion per year from 2021 through 2030 under the department’s cost assumptions.

  • Report October 29, 2015

    CBO estimates that the cost of the Navy’s 2016 shipbuilding plan—an average of about $20 billion per year (adjusted for inflation) over 30 years—would be $4 billion higher than the funding that the Navy has received in recent decades.

    The Navy can sustain its forward presence under smaller shipbuilding budgets by using longer deployments, more overseas basing, and more rotating crews. But those methods would offset some of the savings and have other disadvantages.

  • Report January 22, 2015

    CBO estimates the Administration’s plans for nuclear forces would cost $348 billion over the next decade, close to last year’s estimate. However, projected costs for both the Departments of Defense and Energy have changed somewhat.

  • Report November 20, 2014

  • Report April 2, 2013

    CBO compares the Army’s plan for the GCV with four options and finds that, although no option would meet all of the Army’s goals, all are likely to be less costly and pose a smaller risk of delay than CBO expects for the Army’s plan.

  • Report November 18, 2011

    Between 2012 and 2041, the Navy will: purchase 20 amphibious ships at a cost of about $50 billion; retire 22 amphibious ships; and meet or exceed the 33-ship goal between 2017 and 2031 but fall below the goal the rest of the time.
