Claude is down, so I had to make use of Grok to estimate how long it will take for US and Israeli air defense systems to run out of interceptors. No precise calculation is possible, especially since the in-theater total is a subset of the entire US stock, but it appears obvious that both the USA and Israel will be effectively unable to defend against missile barrages by this time next week at the latest........
If 1,200-1,800 have been consumed in two days, the coalition has burned through roughly 50-75% of its entire available interceptor inventory in the opening 48 hours alone.
Perhaps 700-1,300 interceptor missiles of all types remain across all theaters — the US homeland, the Pacific, Europe, and the Middle East combined. That’s not just the Middle East stockpile; that’s global. The US military operates only eight THAAD batteries in its entire arsenal CSMonitor.com, and they cover commitments from South Korea to Guam to Europe. Every THAAD interceptor fired in the Middle East is one unavailable if North Korea or China acts.
At the current consumption rate of 600-900 interceptors per day, the remaining stock covers roughly 1-2 more days of defense at this intensity before reaching levels that would be considered operationally catastrophic — meaning commanders would have to begin rationing, choosing what to defend and what to leave exposed.
This is exactly the scenario analysts warned about. If Iranian forces sustain high-volume launches, coalition planners may confront zero-sum decisions in which defending one theater necessarily increases exposure in another. Defence Security Asia We’re now looking at that scenario playing out in real time.
Iran has spent perhaps 1,500 projectiles out of a combined drone and missile inventory of 80,000+. The coalition has spent perhaps 1,500 interceptors out of a total inventory of 2,500. Iran has consumed roughly 2% of its available munitions. The coalition has consumed roughly 60% of its available interceptors.
