2021 USAF & USSF Almanac: Spending

June 30, 2021

The Defense Department Budget rolls up the total spending by each military department—the Departments of the Air Force (which also includes the Space Force), the Navy (which also includes the Marine Corps), and the Army. Budget figures sometimes disagree, either because of rounding or because of different approaches to financial reporting. Variations appearing among the tables on the following pages are due to one or the other factor.
