US used double amount of interceptors as Israel during Iran war, officials say - report

During Operation Epic Fury, US forces expended more than half of their THAAD interceptor stockpile defending Israel against Iranian missiles, according to US officials. In response, Lockheed Martin has begun construction on a new production facility in Alabama, while allies like Japan and South Korea express concern over stockpile depletion.

Lead

During Operation Epic Fury, the US expended more than half of its Terminal High Altitude Area Defense (THAAD) interceptors defending Israel against Iranian missile attacks, according to a report by The Washington Post citing US officials who spoke on condition of anonymity. The revelation has prompted Lockheed Martin to break ground on a new production facility in Alabama, while US allies, including Japan and South Korea, have expressed concerns about the sustainability of interceptor stockpiles.

Coverage comparison

Two articles from The Jerusalem Post, published within days of each other, provide complementary details on the defensive efforts and their aftermath. The first report, published on May 22, 2026, focuses on the comparative use of interceptors by the US and Israel, while the second, from May 25, 2026, highlights the industrial response from Lockheed Martin. Both draw on the same underlying Washington Post report, and both attribute key figures to anonymous US officials. While the first piece adopts an analytical tone, comparing US and Israeli defensive efforts, the second is more informative, emphasizing the urgency of replenishing stockpiles.

Key claims

According to the Washington Post report, the US deployed roughly 200 THAAD interceptors against Iranian missiles targeting Israel, which is about half of the total US THAAD interceptor inventory. Additionally, the US Navy used more than 100 Standard Missile-3 and Standard Missile-6 interceptors aboard ships in the Mediterranean. In contrast, Israel used fewer than 100 Arrow 3 missiles and around 90 David Sling interceptors, many of which were aimed at threats from Houthi forces in Yemen and Hezbollah in Lebanon rather than Iranian ballistic missiles.

The reports highlight that US allies have raised concerns about the depletion of interceptor stockpiles. Japan and South Korea are among the most concerned, given their security situations relative to China and North Korea. The production capacity currently does not allow for rapid replenishment; estimates suggest it could take three to eight years to rebuild the THAAD missile stockpile, with each interceptor costing roughly $12.7 million, based on projections from a single source.

In response to the depletion, Lockheed Martin has begun construction on a new munitions production center in Troy, Alabama. The facility will add 87,000 square feet of production space for THAAD interceptors and future work on the Next Generation Interceptor (NGI). This investment is part of Lockheed's broader $9 billion plan over the next decade to increase munitions production capacity and modernize over 20 facilities across the US.

Perspectives

US officials, including Pentagon spokesman Sean Parnell, have defended the interceptor usage, stating that "Both Israel and the United States carried the defensive burden equitably during Operation Epic Fury," and that the operations were coordinated at the highest levels. The Israeli Embassy in Washington echoed this sentiment, emphasizing the close coordination between the two countries.

However, the scale of US interceptor expenditure—more than half of its THAAD stockpile—raises strategic questions about US capacity to respond to simultaneous conflicts. The concerns voiced by allies like Japan and South Korea suggest that the war with Iran has exposed vulnerabilities in missile defense supply chains, potentially affecting deterrence in other regions. Lockheed Martin's rapid response indicates an acknowledgment of the urgency, but the multi-year timeline for replenishment highlights the logistical challenges ahead.

What was claimed, and who backed it

Each row is one claim, attributed to the outlet whose wording states it most clearly. Confidence rates how directly the source text states the claim — explicit and unhedged rates high; hedged, pieced-together, or internally inconsistent statements rate lower. It does not measure whether the claim is true. Status counts the distinct outlets we found asserting it — so a single-source claim can still show high confidence, and a multi-source claim can show medium. Every one of those outlets is named beside the status, so you can check the count against the list. For claims extracted before we began storing that list, the row says so: it names the outlet the claim is quoted from and states that we have not recorded which outlets backed it. Outlets wrote at different times, so a figure that evolves — a casualty count, for example — can legitimately differ between rows; check the "as of" time next to each claim's source.
