How the US used its bunker-buster bombs at Iranian nuclear sites
The deep penetrating bombs that the U.S. dropped into two Iranian nuclear facilities were designed specifically for those sites and were the result of more than 15 years of intelligence and weapons design work. Defense Secretary Pete Hegseth and Gen. Dan Caine, chairman of the Joint Chiefs of Staff, also said at a press briefing Thursday that they are confident the weapons struck exactly as planned. Caine offered new details about the work that went into building the “bunker-buster” bombs and how the U.S. used them to burrow into the Iranian sites. He sought to show the level of destruction but did not directly address President Donald Trump’s assertion that Tehran’s nuclear program has been “obliterated.”
