The Pentagon is confronting a growing reality after months of fighting Iran: America's stockpile of missile defense interceptors.It is shrinking so much, military planners are weighing whether they can continue the current cycle of limited retaliatory strikes.The Center for Strategic and International Studies, using open-source budget numbers provided to Congress, estimates U.S.Patriot interceptor inventories have fallen from roughly 2,300 pre-war to fewer than 827.

Similar to the THAAD interceptors as well," said Kelly Grieco, a missile expert at the Stimson Center."These are things that we have to intercept ballistic missiles.Almost half of THAAD interceptors have been used.
So that's global inventory.So that really leaves us with very little excess to be able to use in other theaters, whether it's defending US forces in Europe or the Indo-Pacific.
So this becomes quite a constraint, I would say, on the United States capabilities, not just today, but in the years to come."The Pentagon’s $67 billion request for fiscal year 2026 emergency funding includes $18.2 billion to replace the U.S.’s most advanced Patriot missile, Navy Tomahawks and the Army’s high-altitude interceptor known as THAAD, according to Bloomberg. Half of the munitions requested in the Pentagon's 2027 budget are low-cost munitions worth $600,000 or less. US NAVY PLANS MAJOR TORPEDO STOCKPILE OVERHAUL AS MILITARY SHIFT...
