The United States conducted an airstrike on an Iranian ammunition depot in Isfahan, using 2,000-pound bunker buster bombs. The strike resulted in a series of massive explosions, producing a large cloud of smoke visible from space. President Donald Trump shared a video of the strike on Truth Social, though he did not provide additional details about the operation.
The strike targeted a facility near Mount Soffeh, an area believed to house military positions and possibly one of Iran’s largest nuclear facilities. Isfahan is also home to Iran’s Badr military air base, a key site for missile production. The explosions were so powerful that they were detected by weather satellites.
In June 2025, Iran reported to the International Atomic Energy Agency (IAEA) that it had constructed a new underground uranium enrichment facility in Isfahan. However, the IAEA has not yet inspected the site, leaving uncertainties about its capabilities.
The strike comes amid escalating tensions in the region, with Israeli Prime Minister Benjamin Netanyahu stating that the war is past the halfway point. The U.S. has previously targeted Iranian nuclear facilities, including the Fardow and Natanz sites in June 2025, using specialized bunker buster bombs to disrupt Iran’s nuclear program.
The use of bunker buster bombs is part of a broader strategy to counter Iran’s extensive underground tunnel and bunker networks, which have been used to protect military assets from aerial strikes. Similar tactics have been employed by Israel in Gaza and Lebanon to target underground infrastructure.
