According to Pentagon spokesman Adam Stump, the 9,797 kilograms heavy, GBU-43 bomb, GPS-guided munition, which was first tested in March 2003, had eleven tons of explosives. It was dropped from a MC-130 aircraft in the Achin district of Nangarhar province. However, he did not give detail of the damages caused by the bombing.
