Massive Ordnance Penetrator (MOP)

The massive ordnance penetrator (MOP), or GBU-57, is the most powerful, anti-bunker, smart bomb that has ever been built so far. It was developed and produced by Boeing for the US Air Force to be theoretically used in a war against Iran to stop its nuclear weapons development program by attacking this country’s nuclear fuel enrichment facilities, which are protected in deep, underground, concrete bunkers in the Iranian mountains. The other likely targets to be attacked are in North Korea, which keeps a nuclear weapons storage in the mountains. Guided by GPS, the MOP can penetrate 60 ft (20 m) of concrete, being three times more powerful than the GBU-28 bunker buster bomb, which has been in the US Air Force inventory for the past few years. The US government has ordered 20 GBU-57 bombs, which were designed to be carried in B-52 Super Fortress and B-2 Spirit bombers.
