In 2023, the United States spent around 916.02 billion U.S. dollars on its military. U.S. military spending has been increasing in current dollar terms since 2016. Spending increased dramatically in 2022 after the Russian invasion of Ukraine. After the first year of the war, the U.S. had contributed more than 40 billion euros worth of military aid to Ukraine. What military spending entails Military spending in the United States is the part of the national outlays of the Department of Defense. While the department has over two trillion dollars in budgetary resources, its outlays - money actually paid out - are significantly lower. This budget is designated for the four branches of the United States military, and is used for everything from salaries, trainings, development of new military technologies, and new aircraft and weaponry. The high cost of U.S. spending The United States is well known for spending more on its military than any other country. In 2023, it was estimated that per capita defense spending amounted to 2,220 U.S. dollars. While this figure is extremely high, many Americans may find it worthwhile, as a majority believe the United States to be the number one military power in the world.
