US military burned nearly 80% of missile interceptors in Iran war: report

The US military has burned through nearly 80% of its interceptors for a critical missile defense system amid the ongoing war with Iran, according to multiple sources familiar with the latest inventory data cited by CNN.

Senior military commanders are warning that overall munitions stockpiles are “dangerously low,” raising serious questions about readiness for prolonged operations or potential future conflicts.

Stockpiles of key air defense systems have been particularly hard-hit.

The US has expended nearly four-fifths of its THAAD (Terminal High Altitude Area Defense) missile inventory relative to pre-war levels and roughly half of its Patriot interceptors since the conflict began, two sources told CNN.

The Center for Strategic and International Studies estimated the US held about 452 THAAD missiles and around 2,200 of the most modern Patriot variants before the war.

The scale of THAAD depletion had not been previously reported.

The US Army has also used “virtually all” of its highly accurate long-range precision strike weapons, including Army Tactical Missile Systems (ATACMS) and Precision Strike Missiles (PrSM), sources said.

Close to half of the global Tomahawk cruise missile stockpile has been expended as well.

These shortages factored into recent high-level discussions and contributed to President Donald Trump’s decision to cancel planned strikes on Iran over the weekend.

Gulf allies have voiced fresh concerns that limited air defense stocks could leave them vulnerable to Iranian retaliation, particularly against energy infrastructure, if the conflict escalates further.

Several of those countries depend on US systems.

One source familiar with the stockpile issues warned: “The lack of interceptors means that conventional attacks can backfire if the suicide drones start making it through in-masse. Tit-for-tat will never end this.”

Pentagon and White House officials pushed back against the gravity of the reports.

Chief Pentagon spokesman Sean Parnell stated: “America’s military is the most powerful in the world and has everything it needs to execute at the time and place of the President’s choosing.”

White House spokesperson Anna Kelly added that the military “has more than enough munitions, ammo, and stockpiles to serve all of President Trump’s strategic goals and beyond,” while noting efforts to urge defense contractors to increase production of made-in-America weapons.

Replenishing the depleted inventories will take years in many cases.

Current production rates deliver only about 15 new Tomahawks and 20 new Patriot missiles per month.

Analysts at the Center for Strategic and International Studies estimate it could take three or more years to restore THAAD stocks to pre-war levels.

The Defense Department has moved to accelerate production, including recent deals to expand rocket motor manufacturing for Patriot and THAAD systems, but results will not be immediate.

The shortages also carry broader strategic implications, experts note, potentially constraining the US military’s ability to respond to contingencies involving China, Russia, or North Korea.

Trump has described current diplomatic efforts as Iran’s “last chance” for a deal, while keeping military options open.
