U.S. Used Bunker Busters in Warfare for the First Time

“The U.S. bombers that attacked Iran’s nuclear sites dropped GBU-57 Massive Ordnance Penetrators, bunker-busting bombs designed to destroy hardened underground targets, for the first time in warfare,” the Wall Street Journal reports.

“A dozen of the bombs were dropped on the Fordow enrichment facility, which is buried under a mountain, and another two were used against the enrichment site at Natanz, a defense official said. Tomahawk cruise missiles also were fired from submarines at Natanz and Isfahan, the official said. The U.S. was known to have produced around 20 of the giant munitions.”
