Pentagon plans massive boost in missile-defense interceptors amid Iran conflict and China threat
The Pentagon is overhauling its missile-defense buying strategy, proposing a sharp rise in PAC-3 MSE and THAAD interceptor purchases after extensive use in the Iran war.
After years of relatively modest purchases, the Pentagon’s FY2027 budget proposes a dramatic expansion of missile-defense interceptors, with the Army requesting thousands more PAC-3 MSE missiles and moving THAAD production under its control to support 857 interceptors. The shift comes after the United States exhausted much of its Patriot and THAAD stockpiles while protecting Israel, American troops in the Middle East and ships in the Red Sea during the conflict with Iran.
Experts note that past budget trade-offs limited acquisitions, leaving a shortfall that could be critical in a prolonged China confrontation. Heritage Foundation analysis estimates current U.S. production capacity at 620 PAC-3 MSE and 96 THAAD units per year, far below the 7,082 and 1,394 interceptors it deems necessary for a minimum viable Chinese contingency. The plan relies on new agreements with defense contractors and mandatory funding, but scaling up manufacturing will take years. Officials stress that securing congressional appropriations and expanding the supply chain are essential to close the interceptor gap.
Why it matters
U.S. missile-defense readiness may be insufficient for a sustained conflict with China, prompting a costly procurement overhaul.
