US Struck Iran's Fordow Nuclear Site With 30,000-Pound Bunker-Buster Bombs

The Pentagon confirmed that a weekend strike on Iran's deeply buried Fordow Fuel Enrichment Plant used 30,000-pound GBU-57 massive ordnance penetrators — among the largest conventional weapons in the US arsenal. The Defense Department reported the details on July 21, 2026. Fordow enriches uranium underground; the GBU-57 is designed to penetrate fortified sites. The strike occurred as the broader US-Iran conflict neared its second week.
