ReportMay 14, 2018
The Navy could use several approaches to increase the size of its fleet. This report focuses on reactivating decommissioned ships, drawing insights from past experiences that might inform lawmakers’ decisions about reactivating ships.
ReportApril 27, 2018
CBO regularly analyzes the Navy’s shipbuilding programs and produces its own estimates of the costs of new ships. CBO’s method relies on historical experience, with adjustments for rate, learning, acquisition strategy, and economic factors.
ReportMarch 14, 2018
CBO estimates that the costs of achieving a 355-ship Navy under two different approaches would average over $100 billion annually through 2047. Those scenarios are compared with two others that would cost less and involve a smaller fleet.
ReportFebruary 16, 2018
This report examines the depot-level maintenance experiences of aging combat aircraft currently in use by DoD and provides insights for the Congress and DoD to consider as the F-35 fleet enters service.
ReportDecember 4, 2017
CBO estimates that inflation-adjusted costs for the Department of Defense would climb from the $575 billion requested in 2018 to $688 billion in 2027 if DoD pursued goals that Administration officials have articulated for the military.
ReportOctober 31, 2017
CBO estimates that the Obama Administration’s 2017 plans for nuclear forces would cost $1.2 trillion (in 2017 dollars) over the 2017–2046 period. CBO analyzed nine options that would reduce those costs or delay some of them.
ReportApril 24, 2017
CBO estimates that construction costs to build a fleet of 355 ships would average $26.6 billion (in 2017 dollars) per year over the next 30 years, which is 60 percent more than what the Navy has spent on average over the past 30 years.
ReportApril 6, 2017
The Obama Administration’s final defense plan called for base-budget funding averaging $540 billion (in 2017 dollars) from 2017 through 2021, but it would have reached almost $600 billion per year by 2032 under DoD’s cost assumptions.
ReportFebruary 21, 2017
CBO estimates that the cost of the Navy’s 2017 shipbuilding plan—an average of about $21 billion per year (in 2016 dollars) over 30 years—would be $5 billion higher than the average funding that the Navy has received in recent decades.
ReportFebruary 14, 2017
CBO estimates that existing plans for U.S. nuclear forces would cost $400 billion over the 2017–2026 period—$52 billion more than CBO’s 2015 estimate for the 2015–2024 period, largely because modernization programs will be ramping up.
ReportJanuary 14, 2016
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.
ReportMarch 13, 2015
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.
ReportNovember 20, 2014
The Department of Defense’s base budget increased by 31 percent (adjusted for inflation) between 2000 and 2014, mainly because of higher costs for military personnel and operation and maintenance.
ReportApril 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.
ReportNovember 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.
