15 Years in the Making: US Reveals How It Targeted Iran’s Deepest Nuclear Bunker

The Pentagon has unveiled unprecedented details about its June 21 strike on Iran’s Fordo nuclear facility, revealing a 15-year secret mission to develop and deploy bunker-busting GBU-57 bombs.

The operation, involving stealth B-2 bombers and precision strikes down concrete-capped ventilation shafts, was designed to neutralize one of Iran’s most heavily fortified underground nuclear sites.

While President Trump calls the mission a total success, early intelligence assessments suggest the damage may have delayed Iran’s program by months, not years.

The release of these details is part of a White House effort to counter media skepticism and assert the strike’s effectiveness.
