According to the Wall Street Journal, GBU-57 ground drill bombs specifically designed to hit underground targets against Iran's nuclear facilities, in particular the Fordo nuclear facility, are likely to be used in operations. According to the Wall Street Journal, the GBU-57 drill bomb is a heavy drill bomb, 20 feet long, about 6 meters long; weighs 30,000 pounds, or 13.6 tons; it is the “most powerful bomb” in the world after nuclear weapons, and can destroy targets buried deep underground, so it is also known as a “bunker bomb.”
