The Air Force has deployed an upgraded version of the U.S.’s largest non-nuclear bomb -- a 30,000-pound “bunker-buster” that can only be carried by the B-2 stealth bomber [...] A fourth upgrade to the Boeing Co. bomb, the GBU-57, has been completed and the existing inventory is being retrofitted, [...] In May, the Air Force dropped three of the bombs from B-2s over the White Sands Missile Range in New Mexico, in a test that demonstrated the weapon’s effectiveness, [...] also known as the Massive Ordnance Penetrator, [OZ: don't confuse with 21,600-pound MOAB which] can only be dropped by pushing it out of an MC-130 propeller aircraft

Little authoritative information has been published about the capability of the GBU-57. A December 2007 story by the Air Force News Service said it has a hardened-steel casing and can reach targets as deep as 200 feet (61 meters) underground before exploding. The 20.5-foot-long bomb carries more than 5,300 pounds of explosives and is guided by Global Positioning System satellites,
