The United States recently announced a replacement for its GBU-57 MOP, or Massive Ordnance Penetrator, which is the largest bunker buster ever fielded.
The MOP went viral in recent weeks after 14 of these 30,000-pound weapons were dropped by seven B-2 Spirit stealth bombers over Iran’s underground nuclear enrichment facilities in Natanz and Fordow.
The GBU-57 is rated to penetrate upwards of 200 feet of earth or more than 25 feet of steel-reinforced concrete. In the attack against the Iranian underground facilities, the U.S. Air Force layered these strikes on top of one another to increase the munition’s maximum penetration depth.
However, for the future, the Air Force wants an even more capable bunker buster – and this is currently being developed under the name of “Next Generation Penetrator,” or NGP.
