Iran’s Underground Nuclear Sites Not Immune To U.S. Bunker-Busters, Experts Say [View all]

[Purveyor]

By Joby Warrick,

Western spy agencies for years have kept watch on a craggy peak in northwest Iran that houses of one the world’s most unusual nuclear sites. Known as Fordow, the facility is built into mountain bunkers designed to withstand aerial attack. Iran’s civil-defense chief has declared the site “impregnable.”

But impregnable it is not, say U.S. military planners who are increasingly confident of their ability to deliver a serious blow against Fordow, should the president ever order an attack.

U.S. officials say they have no imminent plan to bombard the site, and they have cautioned that an American attack — or one by its closest Middle Eastern ally, Israel — risks devastating consequences such as soaring oil prices, Iranian retaliation and dramatically heightened tension in a fragile region.

Yet as a matter of physics, Fordow remains far more vulnerable than generally portrayed, said current and former military and intelligence analysts. Massive new “bunker buster” munitions recently added to the U.S. arsenal would not necessarily have to penetrate the deepest bunkers to cause irreparable damage to infrastructure as well as highly sensitive nuclear equipment, likely setting back Iran’s program by years, officials said.
