In the US, they demonstrated how anti-bunker bombs work

The chairman of the Joint Chiefs of Staff of the US Army, Dan Kaine, showed footage of the GBU-57 MOP anti-bunker bomb in action.

“Unlike conventional bombs, this bomb does not create a crater when it hits, because it is designed to penetrate deep into the ground and then explode,” he noted.

Speaking about the attack on Iranian facilities, Dan Kaine added that all six bombs dropped on the Fordow nuclear facility exploded exactly where they were intended.
