U.S. Critical Weapons Stockpiles Could Be Depleted Five Weeks Into Iran War, Analysts Claim

Researchers said 11,294 munitions were fired in 16 days, and some THAAD, ATACMS and Precision Strike Missile stocks could be exhausted by mid-April.

  • Analysts warn U.S. stockpiles of advanced air defense interceptors and ground-attack missiles could run dry in weeks if fighting with Iran continues. Royal United Services Institute commentary published on Tuesday indicates Terminal High Altitude Area Defense interceptors may deplete by April 17.
  • The coalition expended 11,294 munitions during the initial 16 days of the war, with roughly 5,000 fired in the first four days alone. Researchers estimate replenishing these stocks at speed would cost $50 billion.
  • Restocking air defense systems requires about 8,800 pounds of tungsten, a metal for which China controls over 80% of the global supply. Pentagon records show at least 328 PrSM missiles manufactured in the last two years.
  • Given that Iran has damaged at least a dozen allied radars and satellite terminals, using 10 or 11 interceptors for one missile or 8 Patriot missiles for one drone becomes unsustainable, the researchers wrote. This implies accepting greater risk for aircraft and tolerating more missile and drone 'leakers' damaging forces.
  • Researchers urged building a 'patchwork shield' by layering cheaper and more advanced air defenses. "Command of the commons remains necessary, but Epic Fury demonstrates it is increasingly insufficient without 'Command of the Reload'," they wrote.
