Illustrative Options for National Defense Under a Smaller Defense Budget
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.

The Capacity of the Navy’s Shipyards to Maintain Its Submarines
The Navy’s shipyards have experienced significant delays in completing maintenance on submarines. In this report, CBO projects that required maintenance will continue to exceed the shipyards’ capacity and examines options to reduce delays.

Alternatives for Modernizing the Navy’s Sealift Force
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.

The Personnel Requirements and Costs of New Military Space Organizations
CBO estimates the added personnel requirements and costs of five kinds of military space organizations. DoD wants to create three, which could increase annual costs by $1 billion to $2 billion and require onetime startup costs of $2 billion to $5 billion.

The Army’s Ground Combat Vehicle Program and Alternatives
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.
