America Deploys Weapons in Gulf as Iran Sanctions Near and Tensions Mount:
"...the U.S. Air Force is continuing to fast-track modifications of a Super Bunker Buster--formally known as the GBU-57A/B at Eglin Air Force Base in Florida. Modifications would allow it to be carried in the bay of a radar-evading B2a Stealth Bomber, according to Eglin base sources. The B2a is one of only two airplanes that can carry the 30,000 pound bomb which is designed to cause massive concussions more than 200 feet below the earth where Iran is thought to have burrowed its nuclear program."
