Defense Budget and Spending

Defense budget and spending covers how the federal government decides how much to spend on the military, where that money goes, and who signs off along the way. It touches everything from fighter jets and aircraft carriers to troop pay and base infrastructure, and it consistently makes up one of the largest pieces of federal discretionary spending.

Building the budget. The Pentagon’s budget doesn’t simply appear; it moves through a defined cycle of requests, negotiations, and votes that shapes what the military can buy and do for years afterward. Understanding the DoD Budget Process walks through how that cycle works, while How the Pentagon Spends Your Money: A Guide to Defense Dollars breaks down where the funds actually flow once approved.
