A report from the Jewish Institute for National Security of America (JINSA), obtained by Fox News Digital, warns that U.S. allies in the Gulf region have severely depleted their air defense interceptor stockpiles during the Iran war, with Bahrain expending up to 87 percent of its Patriot missiles, the UAE and Kuwait each using roughly 75 percent, and Qatar approximately 40 percent. Israel shows signs of rationing its advanced interceptor systems, declining to engage some lower-tier threats in order to preserve expensive interceptors for high-value targets. Fox News confirmed the depletion figures; NBC News separately reported on the Pentagon's $200 billion war funding request that includes interceptor restocking as a major cost driver.

The strategic concern at the center of the JINSA report is an acute cost asymmetry: Iranian attack drones cost approximately $30,000 each to produce, while the interceptor missiles used to shoot them down — particularly advanced systems like the Arrow — cost millions of dollars per shot. As the report's cited expert explained: "Building a missile in Iran may cost a few hundred thousand dollars, while the interceptor costs millions, especially when we talk about systems like Arrow." This arithmetic means Iran can potentially sustain a war of attrition on air defense spending — firing cheap drones to drain expensive interceptors faster than allies can manufacture replacements — even as its broader military capabilities are degraded by U.S. and Israeli strikes.

The problem is compounded by industrial capacity constraints on the allied side. Patriot missile components involve specialized production lines with long lead times; the U.S. defense industrial base was already under stress from Ukraine war demand before the Iran conflict added simultaneous pressure. The $49 billion in defense acquisition cost overruns documented by the GAO — a figure that motivated the Hawley-Warren defense contractor accountability bill introduced Wednesday — includes interceptor production as a key bottleneck. Over 90 percent of Iranian missiles and drones have been successfully intercepted since the war began, an impressive performance metric, but one achieved at a rate of interceptor consumption that cannot be sustained indefinitely without significant new investment.

The interceptor depletion issue directly informs the Iran war's financial demands on Congress. The Pentagon's $200 billion emergency supplemental request — larger than any single war spending bill for Afghanistan or Iraq — includes substantial interceptor restocking and production acceleration as core components. Senate Republicans, led by Graham, are considering packaging Iran war funding in a second reconciliation bill that could pass on a party-line basis. The strategic vulnerability created by interceptor depletion strengthens the administration's argument to Congress that the $200 billion request is militarily necessary rather than a political choice, since a degraded allied air defense posture creates risk even if Iran's offensive capabilities have been significantly reduced.
