Is the US really running out of weapons under Trump ?

What Happened

According to a CSIS analysis, US munitions stockpiles are significantly depleted following nearly 40 days of combat operations against Iran during Operation Epic Fury, which ended with a 8 April ceasefire. US forces struck over 13,000 targets and intercepted over 1,700 Iranian drones and ballistic missiles, at a cost of $37.5 billion. The CSIS estimates that more than 1,000 Tomahawk Land Attack Missiles were fired, with pre-war stockpiles not expected to recover until 2031; 1,430 Patriot interceptors were used from an estimated pre-war stock of 2,330; and between 190 and 290 THAAD interceptors were launched from only 360 available. President Donald Trump denied any shortfall, while Secretary of Defense Pete Hegseth initially backed that stance but later asked Congress for $87 billion to address 'critical shortfalls'. A New York Times report claimed Trump was advised to avoid escalation due to stockpile concerns. CSIS adviser Mark Cancian noted missile production takes one to five years, creating a 'window of vulnerability'.

Key Actors

Why It Matters

The munition depletion comes as the US faces a potential confrontation with China over Taiwan, with some analysts pointing to a possible Chinese invasion by 2027. The heavy expenditure on advanced, hard-to-replace systems like Tomahawks, Patriots, and THAADs could undermine US readiness and deterrence in the Pacific, leaving a window of vulnerability that adversaries might exploit.

Watch For

Monitor Congressional action on the Pentagon's $87 billion emergency funding request; further stockpile and readiness assessments from the Pentagon or CSIS; progress in US-Iran negotiations following the ceasefire; and any Chinese military activity or statements regarding Taiwan as the 2027 Davidson window approaches.
