U.S. Penetrator Bomb Could Put Iranian Underground Targets at Risk

Recent updates to a U.S. bomb designed to pulverize subterranean targets have been effective, the Pentagon's testing czar determined this week in an annual report.

The Boeing-developed Massive Ordnance Penetrator could be delivered by B-2 bombers in a potential attack on Iran's atomic facilities, some of which have been built underground, Bloomberg reports. Tehran has agreed to halt some of its sensitive atomic activities for the next six months while it negotiates a deal with world powers to resolve concerns about its potential to develop a nuclear weapon.


U.S. testing last year demonstrated that the Enhanced Threat Modification upgrade to the penetrating bomb has given the 30,000-pound conventional munition the ability to "effectively" destroy "selected hardened, deeply buried targets," concluded Michael Gilmore, head of the Pentagon's testing and evaluation office, in his report on major weapon systems.
