Long-Term Implications of the 2024 Future Years Defense Program

In most years, the Department of Defense (DoD) produces a five-year plan, called the Future Years Defense (FYDP), that is associated with the budget it submits to Congress. The 2024 FYDP, issued in May 2023, comprises DoD’s request for appropriations in 2024 and a series of planned budgets for 2025 through 2028.

In this report, the Congressional Budget Office analyzes the 2024 FYDP and summarizes DoD’s expectations about the costs of its plans for 2024 through 2028. Because decisions made in the near term can have consequences for the defense budget in the longer term, CBO projected the costs of DoD’s 2024 plan through 2038, 10 years beyond the period covered by the current five-year plan.
