Last April, the US military detonated the “mother of all bombs”—a GBU-43/B Massive Ordnance Air Blast (MOAB), with 18,000 pounds of explosives—over an ISIS tunnel complex in Afghanistan. This being the first use in combat of the giant MOAB, its use in Afghanistan generated widespread press attention. In many of the media commentaries, the GBU-43/B was described as the largest non-nuclear weapon in the US arsenal—as powerful, in fact, as the smallest nuclear weapons developed by the United States. In turns out, however, that the GBU-43/B is eclipsed by an even larger non-nuclear weapon, the 30,000-pound GBU-57 Massive Ordnance Penetrator (MOP), dubbed by some the “father of all bombs” to distinguish it from the MOAB. Originally designed to destroy underground nuclear facilities in Iran, the GBU-57 is now being readied for use against North Korea.
