Military Spending in the United States 2025
The United States continues to maintain its position as the world’s largest military spender in 2025, with unprecedented defense allocations that underscore the nation’s commitment to national security and global military superiority. The fiscal year 2025 national defense budget is capped at $895 billion, representing a substantial investment in America’s defense capabilities and strategic priorities. This massive allocation demonstrates the country’s dedication to maintaining technological superiority, modernizing military assets, and addressing evolving global security challenges.
The scale of American military spending in 2025 reflects complex geopolitical realities and strategic imperatives that shape defense policy decisions.
