U.S. Military Spending Has Increased Tenfold Over the Last 50 Years

"Over the past half-century, U.S. military spending has skyrocketed to levels unimaginable in earlier generations. The amount of money spent on our nation's military has risen nearly tenfold as global conflicts, technological advancements, and evolving political priorities influence defense strategy. Our national military is now defined as a sprawling, high-cost system backed by cutting-edge weapons, mass deployments, and a constant priority to maintain dominance."

"24/7 Wall St. identified what the U.S. spent on the military each year over the last 50 years by reviewing data on U.S. military spending from the Stockholm International Peace Research Institute Military Expenditure Database, listing the years 1973-2022. Figures are in current U.S. dollars. We also calculated the percentage change in military spending from the previous year and the spending as a percent of GDP."

"It's important to explore the dramatic rise in U.S. military spending because it directly affects everything from national priorities, global influence, and the everyday lives of American citizens. Understanding where trillions of dollars go and how this massive sum contributes to our defense helps the public feel secure. Citizens can evaluate whether current defense spending aligns with today's security challenges or seems unnecessary and outdated."

U.S. military spending has grown dramatically over the past half-century, rising nearly tenfold and producing a sprawling, high-cost defense apparatus focused on advanced weaponry and large-scale deployments. Key drivers include global conflicts, technological advancements, and shifting political priorities that emphasize maintaining dominance. Annual figures, measured in current dollars for 1973–2022, show year-over-year percentage changes and spending as a share of GDP based on SIPRI data. The scale of spending reshapes federal budgets and affects allocations for healthcare, education, infrastructure, and social programs while raising questions about long-term security priorities and fiscal sustainability.
