Senior Pentagon officials have revealed new details about the U.S. operation to bomb three nuclear sites in Iran, which was described as the "largest B-2 operational strike in U.S. history." The chairman of the Joint Chiefs of Staff, Gen. Dan Caine, said the strikes inflicted "extremely severe damage and destruction" on the targets at Fordo, Natanz, and Isfahan. The operation was carried out on June 21, 2025, with the president giving the green light after being advised by his defense secretary.

Key Takeaways:

  • The U.S. operation, dubbed Operation Midnight Hammer, involved seven B-2 Spirit bombers flying from Whiteman Air Force Base in Missouri to Iran, with another group of B-2s flying west over the Pacific as decoys.
  • The mission included more than 125 U.S. aircraft, including bombers, fighter jets, refueling planes, and surveillance aircraft, which used over 75 precision-guided weapons in the attack.
  • Initial battle damage assessments indicate that all three sites sustained extremely severe damage and destruction, with the chairman warning Iran against taking any retaliatory action for the strikes.
  • Defense Secretary Pete Hegseth called the attack "an incredible and overwhelming success" and described it as a "bold" and "brilliant" operation that demonstrated American deterrence is back.
  • President Trump announced the strikes on June 21, 2025, evening and warned of "far greater" attacks if Iran does not "make peace," stating that the sites "have been completely and totally obliterated."
  • The operation was described as the "largest B-2 operational strike in U.S. history" and included the first operational employment of the Massive Ordnance Penetrator (MOP), a bomb capable of penetrating deep into fortified bunkers.
  • The lead B-2 bomber dropped two "bunker-buster" bombs, known as the GBU-57 Massive Ordnance Penetrators, on the site at Fordo, with a total of 14 MOPs being dropped on targets at Fordo and Natanz over the next 25 minutes.
  • The operation involved a complex and tightly timed maneuver, with U.S. fighter jets clearing the airspace ahead of the bombers and a U.S. submarine launching over two dozen Tomahawk cruise missiles against targets at the site in Isfahan just before the aircraft entered Iranian airspace.
