World's Largest Bomb Used in Afghanistan: The bomb is so big, it can’t be dropped. It has to be pulled by parachute out the back of a cargo plane. And the Air Force unleashed it over Afghanistan. The BLU-82, a 15,000-pound fuel-air explosive bomb dubbed “Daisy Cutter,” was dropped on Taliban positions behind the front lines on Sunday, The Associated Press reported. It earned its nickname because it is detonated about three feet above ground, and it clears a 900-foot radius. Large weapons such as the Daisy Cutter are viewed not only as intense firepower, but also as psychological pressure on Taliban and al-Qaida forces.
