The United States military is facing a munitions crisis that defense planners have quietly worried about for years. Operation Epic Fury, which commenced on February 28, 2026, has driven American missile and interceptor stockpiles to levels that several analysts describe as critically low. The numbers are starkThe US military has expended at least half of its Patriot interceptor stockpile since the conflict began. Long-range precision munitions tell an even grimmer story: assessments suggest only about 20% of pre-war stocks remain on hand. Pre-war inventories were already strained by years of commitments, most visibly the sustained transfer of munitions to Ukraine.
