Boeing delivers first batch of 30,000-pound bombs to Air Force

"The Massive Ordnance Penetrator is a weapon system designed to accomplish a difficult, complicated mission of reaching and destroying our adversaries' weapons of mass destruction located in well-protected facilities," Lt. Col. Melinda F. Morgan, a Pentagon spokeswoman, said in a statement.

Experts took note of the fact 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. That country 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?" said John Pike, director of Globalsecurity.org, a website for military policy research. "The military hasn't said what underground facility they need to blow up with this thing. Whether it's in Iran or North Korea or somewhere else, I don't know. But they've been asking for this weapon for years."
