President Donald Trump recently announced that the U.S. has bombed three Iranian nuclear sites, officially entering the war. The bombing targeted Fordo, a key underground nuclear facility, and two other sites. The 'bunker buster' bomb is specifically designed to penetrate deeply buried targets.

Trump revealed the bombing on social media, stating that a 'full payload' of bombs had been dropped on Fordo and two other sites. The U.S. had been considering involvement following Israel's initial attack on Iran, with a focus on the American-made 'bunker buster' bomb, capable of penetrating fortified targets like the Fordo nuclear facility.

The Massive Ordnance Penetrator (MOP) is a weapon system designed to destroy well-protected facilities housing weapons of mass destruction. It can only be delivered by the U.S. B-2 Spirit stealth bomber.

The Guided Bomb Unit (GBU) 57, also known as the 'bunker buster,' is a GPS-guided weapon designed to attack deeply buried targets such as bunkers and tunnels. Weighing 30,000 pounds, the bomb has undergone updates over the years, potentially increasing its reach and capabilities.
