Weapon Systems

CBO analyzes the hypersonic missiles being developed by the U.S. military and compares them with less expensive existing or potential weapons that might fill similar roles, such as cruise missiles or ballistic missiles.

CBO analyzes the Department of Defense’s (DoD’s) plans for 2023 through 2027 as presented in the 2023 Future Years Defense Program and projects that DoD’s costs would increase by 9 percent from 2027 to 2037 without the effects of inflation.

CBO issues a volume that contains short descriptions of 59 policy options that would each reduce the federal budget deficit by less than $300 billion over the next 10 years.

Under the three alternatives in the Navy’s 2023 plan, total shipbuilding costs would average about $30 billion to $33 billion per year (in 2022 dollars) through 2052, CBO estimates, as the Navy built a fleet of 316 to 367 battle force ships.

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 examines the availability and use of DoD’s F-35 fighter aircraft. This report includes findings about fleet sizes, availability rates, time spent in depot-level maintenance, flying hours, and the effects of the coronavirus pandemic.

CBO analyzes DoD’s plans for 2022 as presented in the Biden Administration’s 2022 budget request and projects how those plans would affect defense costs through 2031. Those costs would increase by 10 percent over that period, CBO projects.

CBO analyzes patterns in the availability and use of the Air Force’s and Department of the Navy’s aircraft since 2001. CBO also analyzes how the military aircraft have performed since the onset of the coronavirus pandemic.

CBO examined three broad options for reconfiguring the military if funding for the Department of Defense was reduced by $1 trillion (in 2022 dollars), or 14 percent, over the next 10 years.

CBO examines the availability of six Air Force aircraft fleets after large-scale maintenance performed since the mid-1990s. In most of the cases, aircraft were more available after the maintenance action than would be expected without it.

The military services use unmanned aerial systems (UASs) differently than manned aircraft. UASs generally have lower recurring costs per flying hour, but their cost advantage may be smaller when the cost of acquiring the aircraft is considered.

This update of CBO’s 2016 primer on the structure of the U.S. military describes the size, functions, and operation and support costs of every major element of the armed forces.
