CSBA’s research on the most pressing issues in U.S. national security continues to shape the defense agenda. CSBA’s research focuses on four main areas:
Strategy & Policy
Budget & Resources
CSBA plays an essential role in facilitating a more informed debate on defense budgeting and resourcing.
The perennial question for U.S. policymakers is: How much is enough? Following a long military buildup, the U.S. military confronts increasing pressures for cuts in defense spending in light of the United States’ deteriorating fiscal situation. The Defense Department is entering what may be a protracted period of austerity which will require difficult budgetary and resourcing decisions.
CSBA’s research program provides an independent source of budgetary analysis to help those both in and out of government understand budgetary trends; the near-and long-term implications of prospective trade-offs; the second-order consequences of changes to the defense program; and how they fit within the overall context of U.S. defense policy and strategy.

Relook Playbook: Defense Budgeting Insights From a CSBA Rebalancing Exercise
In February 2025, Defense Secretary Pete Hegseth directed the Pentagon to reexamine the 2026 budget request, which has been drafted but not sent to Congress, to ensure that it reflected the Trump administration’s priorities. Specifically, he tasked the military departments and defense agencies with identifying lower-priority activities totaling 8 percent of their projected annual budgets from 2026 to 2030. These lists of potential cuts will create a substantial pool of money available for potential reallocation.
