Military technology has created some fearsome weapons, such as the 5,000 lb GBU-28 Deep Throat bunker buster, 15,000 lb BLU-82 Daisycutter, 15,650 lb Russian ATBIP (Aviation Thermobaric Bomb of Increased Power), 22,000 lb Grand Slam earthquake bomb, and the 22,600 lb GBU-43 MOAB (Massive Ordnance Air Blast), but if you were hiding under 50 meters of hardened concrete, none of them were going to bother you. Not any more! The U.S. Air Force has just taken delivery of the first GBU-57A/B (Massive Ordnance Penetrator). It weighs 30,000 lb and will penetrate 200 ft of hardened concrete BEFORE it goes off. If you are reading this from an underground nuclear facility in Iran or North Korea, might we suggest some extended sick leave is (or soon will be) in order.
