The 30,000 pound munition, equipped by the U.S. B-2 Spirit stealth bomber may be the only aerial bomb that can reach Iran's Fordow nuclear site.

Israel's escalating conflict with Iran over its increased nuclear as brought up speculation about the possible use of one of America's powerful weapons in the conflict.

MOP s were developed by America’s air force when it found that its existing bunker-busters could not damage Iraqi bunkers during the invasion in 2003. A new weapon had to be rushed into service. The MOP aimed to smash even deeper and harder bunkers being built in Iran and North Korea.
