Summarizing three reports about the aviation fleets of the U.S. Air Force, Army, and the Department of the Navy, CBO projects the number and costs of aircraft the Department of Defense would need to procure to maintain the fleets’ current size through 2050.
In 2016, the military services allocated $25 billion to base operations support (BOS). CBO explores characteristics of bases and the mission of the units they serve, analyzing the relationship between those characteristics and BOS costs.
CBO estimates that the Navy’s plan to modernize and operate its sealift ships over the next 30 years would cost roughly $39 billion. In this report, CBO explores four alternatives that would vary in cost from $34 billion to $40 billion.
CBO estimates that the total shipbuilding budget would average $31 billion per year, one-third more than the Navy estimates. The plan would require an increase of more than 50 percent compared with recent shipbuilding budgets.
According to CBO’s projections, if the plans described in the 2020 FYDP were implemented, DoD’s costs would increase from the $718 billion requested for 2020 to $776 billion (in 2020 dollars) by 2034.
This tool allows the user to see the effects on the Department of Defense’s total operation and support costs and on the size of the military of adding or subtracting tanks, ships, aircraft, and other units.
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.
