NEED TO KNOW

• CSIS estimates the U.S. spent roughly half its Patriot and THAAD interceptors in 39 days
• Trump told reporters last month U.S. munitions stockpiles are "virtually unlimited"
• Replenishment will take one to four years — and longer to reach pre-war levels

WASHINGTON, DC (TDR) — The U.S. military burned through nearly half its Patriot and THAAD interceptors in the seven-week air campaign against Iran, according to a Center for Strategic and International Studies analysis whose figures Pentagon sources told CNN match classified internal data.

The big picture: The numbers contradict the administration's public messaging on stockpile health and surface a problem the Pentagon has been quietly briefing Congress on for weeks.

• The U.S. struck more than 13,000 targets over 39 days before the ceasefire
• Joint Chiefs Chairman Gen. Dan Caine warned Trump before the war that a protracted campaign would strain stockpiles

Why it matters: Interceptor inventories are the last layer of defense for U.S. bases, allied capitals, and the homeland — and they don't get rebuilt quickly.

• THAAD and Patriot interceptor delivery timelines run three to five years per CSIS
• The U.S. supplies the same systems to Ukraine, Israel, and 18 other partner nations

Driving the news: CSIS analyst Mark Cancian published the depletion estimates Tuesday, drawing on FY 2026 budget documents and reported expenditures.

• 45% of Precision Strike Missiles spent
• ~50% of Patriot interceptors expended ($4 million each)
• ~50% of THAAD interceptors gone ($15.5 million each)
• More than 1,000 Tomahawk cruise missiles fired — 10 times the annual procurement rate, per New York Times reporting

What they're saying: The administration and the analysts are reading the same data and drawing opposite conclusions.

• Donald Trump, President — "We have a virtually unlimited supply of these weapons. Wars can be fought 'forever.'"
• Sean Parnell, Pentagon spokesman — The military "has everything it needs to execute at the time and place of the President's choosing"
• Mark Cancian, CSIS — "The high munitions expenditures have created a window of increased vulnerability in the western Pacific"

Yes, but: The CSIS report itself notes the U.S. retains enough munitions to finish the Iran fight if the ceasefire collapses — the shortfall is about the next war, not this one.

• Iranian missile launches dropped 86% from day one to week one
• Cheaper short-range munitions replaced exquisite long-range strikes after early days

Between the lines: Trump's "unlimited" framing isn't sloppy — it's a deliberate choice to deny adversaries the satisfaction of seeing American capacity shrink in real time, even at the cost of contradicting his own Pentagon.

• Chinese state media is already publishing translations of the CSIS figures
• The FY 2027 budget request triples munitions spending to roughly $70 billion — the budget itself concedes what the rhetoric won't

What's next:

• Lockheed Martin has agreed to quadruple THAAD interceptor production from 96 to 400 per year
• The Pentagon is putting missile production on what officials call a "wartime footing"
• Senate Democrats are pressing for hearings on Pacific theater readiness gaps

If preserving munitions for a future war means losing the current one, and winning the current one means inviting the future one — which trade-off does a president owe the public an honest answer about?
