Hugh Pickens writes "In an age of drones and lightweight weaponry, the U.S. Air Force's purchase of the first batch of 30,000-pound bombs designed to pulverize underground enemy hide-outs highlights the military's need to go after hard and deeply buried targets. The weapon's explosive power is 10 times greater than its bunker-buster predecessor, the BLU-109 and it is nearly five tons heavier than the 22,600-pound GBU-43 MOAB surface bomb, sometimes called the 'mother of all bombs.' 'Our past test experience has shown that 2,000-pound penetrators carrying 500 pounds of high explosive are relatively ineffective against tunnels, even when skipped directly into the tunnel entrance,' says a 2004 Pentagon report on the Future Strategic Strike Force. 'Instead, several thousand pounds of high explosives coupled to the tunnel are needed to blow down blast doors and propagate a lethal air blast throughout a typical tunnel complex' (PDF). Experts note that the military disclosed delivery of the new bunker-busting bomb less than a week after a United Nations agency warned that Iran was secretly working to develop a nuclear weapon and is known to have hidden nuclear complexes that are fortified with steel and concrete, and buried under mountains. 'Heck of a coincidence, isn't it?' says John Pike, director of Globalsecurity.org."
