402 Patriots in 16 days: the Iran war drains US interceptor stocks
Operation Epic Fury burned through PAC-3 missiles faster than two years of production can replace
Summary
The 2026 Iran war (Operation Epic Fury) exposed how thin the US interceptor magazine is. The Payne Institute estimates US forces fired ~402 Patriot interceptors in the first 16 days — a draw that Army budget documents imply would take more than two years to replace at current contract rates. Lockheed Martin builds roughly 600 PAC-3 a year (each ~$3.9M) against an estimated inventory near 1,000 PAC-3/MSE, and aims to reach 2,000/year only over seven years. Analysts (CSIS, AEI) frame the drawdown as a strategic warning: a single regional air war strained the stockpile that also underwrites deterrence against China. Supply constraints include test capacity and Chinese- controlled gallium and germanium.
By the numbers
- ~402 — Patriots fired in Epic Fury's first 16 days (Payne Institute).
- ~600/yr — current Lockheed PAC-3 output; target 2,000/yr in seven years.
- ~$3.9M — unit cost of a PAC-3 interceptor.
- ~1,000 — estimated US PAC-3/MSE inventory.
- 2+ years — to replace what was fired at current contract rates.
Why it matters
Interceptors are the binding constraint of modern air defence. A magazine drained by one expensive campaign cannot be quickly refilled, and the degradation is gradual — more leakers get through as stocks tighten. It strains US ability to defend allies and itself simultaneously across two theatres.
What to watch
- Whether surge contracts and second sources actually lift output.
- Allied requests competing with US rebuild (Israel, Taiwan, Ukraine).
- Chinese export controls on gallium/germanium feeding the bottleneck.
