The U.S. Armed Forces depleted their stockpiles of vital missiles to harmful ranges throughout the nation’s seven week struggle towards Iran, leading to a “close to time period danger” that would depart it weak, based on a brand new evaluation revealed by the Middle for Strategic and Worldwide Research (CSIS). Intense fight operations have exhausted a staggering proportion of the nation’s most superior weaponry, together with Precision Strike Missiles (PrSM), Patriot, THAAD, SM-3, and SM-6 air defence interceptors, and Tomahawk cruise missiles, with figures remaining categorised by the Pentagon. Though the Pentagon maintains it has ample firepower to proceed operations towards Iran and its strategic companions, the CSIS report warns that the depletion of munitions has essentially undercut the United Sates’ capability to struggle a significant struggle, which has notably severe implications for the Pacific theatre, the place the US faces peer and close to peer challenges from China and North Korea respectively.
Analysts at CSIS have warned that rebuilding U.S. arsenals will probably be a sluggish and dear course of, with an professional from the suppose tank cited by CNN observing that it could take “one to 4 years to replenish these inventories and a number of other years after that to develop them to the place they should be.” Statements by Pentagon officers have persistently been assessed to be downplaying the extent of the fallout from the struggle. Iran’s sustained air defence functionality restricted the flexibility of hostile plane to function deep inside its territory. This prevented U.S. and Israeli plane from relying totally on low price gravity bombs to strike targets, and meant that top price missiles launched from the air, from on land, and from at sea had been extra closely relied on to strike targets from safer distances. Decrease worth plane equivalent to MQ-9 Reapers, which had been extensively used to function deep inside Iran, have suffered very excessive charges of losses to native air defences.
Analysts have estimated that the U.S. launched assaults on greater than 6,000 Iranian targets within the first 10 days of assaults, nearly all utilizing pricey past visible vary weaponry, whereas additionally firing at estimated greater than 2000 anti-ballistic missiles to intercept Iranian counter strikes. By the ultimate week of March, the Navy was estimated to have expended near 1,000 of Tomahawk cruise missiles, of a complete arsenal of between 3,000 and 4,500 in its complete stock. To put this in perspective, simply 57 Tomahawks had been included in the US’ defence funds in 2025, regardless of depletion of the arsenal from strikes on targets in Iran and Yemen in 2024-2025. Alongside anti-ballistic missiles from the THAAD, system, probably the most closely depleted inventories has been that of GBU-57 bunker buster bombs, which estimated to have been nearly completely used up, whereas being extraordinarily difficult and dear to exchange with prices of over $370 million per bomb.
Director of the Missile Protection Program at CSIS Tom Karako has been amongst a number of to warn that whereas the Pentagon claims its stockpiles are ample for present operations, the continued high-rate expenditure has positioned immense stress on the U.S. Armed Forces’ long-range weapons stock. He highlighted that the US’ failure to take care of ample missile stockpiles over the previous few years has now compelled large depletion within the struggle, placing navy planning officers liable to working out of ammunition. Karako additional famous that avoiding ammunition shortages requires swift motion from Congress and the Pentagon to replenish the ammunition replenishment funds, whereas notably warning that shortages might severely undermine warfighting capabilities within the Pacific.
