US Depletes Critical Missile Stockpiles in Five-Month Iran War

The five-month war with Iran, initiated by Donald Trump and Israel in February 2026, has reached a strategic impasse characterized by severe munitions shortages and rising casualties. Recent reports and analysis from the Center for Strategic and International Studies indicate the U.S. Army has exhausted virtually all its stockpiles of Army Tactical Missile Systems (ATACMS) and Precision Strike Missiles (PrSM). Defensive capabilities are similarly strained, with an estimated 65% of Patriot interceptors and 38% of THAAD munitions expended. Nearly half of the global Tomahawk cruise missile supply has also been used.

These shortfalls, attributed to a preference for stand-off weapons over riskier piloted missions, have reportedly led military advisers to warn the president against launching further massive offensives. In response, the Pentagon requested $67 billion in supplemental funding, and the U.S. Army awarded Lockheed Martin a $58.6 billion contract for PAC-3 MSE interceptors. The administration is also working with Raytheon to accelerate Tomahawk production and has proposed a $1.5 trillion defense budget to modernize autonomous systems.

Despite these data, Trump has dismissed the shortages, asserting the U.S. possesses more munitions than any other nation. However, internal pressure persists from Vice President JD Vance and General Dan Caine regarding escalation risks. The conflict has cost an estimated $37.5 billion, resulted in 18 U.S. service member deaths, and contributed to oil prices exceeding $100 per barrel following Houthi blockades in the Red Sea. While Trump recently issued an ultimatum to Tehran, Qatar's Foreign Ministry indicates that resolution efforts are in progressive stages.
