US Launches Airstrikes on Iran’s Underground Nuclear Sites: Fordow Hit with Bunker-Buster Bombs
Saturday 21 Jun 2025In a major escalation in Middle East tensions, the United States has launched direct airstrikes on Iran’s underground nuclear facilities. The Fordow site, a highly fortified uranium enrichment plant, was among the main targets struck early Saturday, June 21, 2025, using advanced stealth bombers and massive bunker-busting bombs.

What Happened?
According to Associated Press (AP), U.S. B-2 Spirit bombers carried out targeted strikes on Fordow, one of Iran’s most secretive nuclear facilities. The operation involved GBU-57 Massive Ordnance Penetrators, designed to destroy deep underground bunkers.
Former U.S. President Donald Trump confirmed the strike, saying:
“We hit three nuclear sites. The mission was a complete success, and all aircraft returned safely.”
Other Targets
In addition to Fordow, the strikes reportedly hit Natanz and a research center near Isfahan, according to The Washington Post. These sites play a central role in Iran’s uranium enrichment program and have long been viewed as strategic threats by the U.S. and Israel.
Global Reaction
International media, including The Guardian, have described the attack as a dangerous turning point. Experts warn the move could widen the regional conflict, possibly drawing in Lebanon, Syria, and the Red Sea region.
Summary
The U.S. struck Iran’s underground Fordow nuclear site using B-2 bombers and bunker-busting bombs.
Other targets included Natanz and a nuclear research facility in Isfahan.
The strikes mark a significant shift in direct U.S. military involvement in the Iran-Israel conflict.
Global concerns are growing over the possibility of a larger regional war.
