U.S. making bomb capable of destroying Iran’s nuke sites

PanARMENIAN.Net - Pentagon war planners have concluded that their largest conventional bomb isn't yet capable of destroying Iran's most heavily fortified underground facilities, and are stepping up efforts to make it more powerful, according to U.S. officials briefed on the plan.

The Wall Street Journal reports that the 30,000-pound "bunker-buster" bomb, known as the Massive Ordnance Penetrator, was specifically designed to take out the hardened fortifications built by Iran and North Korea to cloak their nuclear programs.

But initial tests indicated that the bomb, as currently configured, wouldn't be capable of destroying some of Iran's facilities, either because of their depth or because Tehran has added new fortifications to protect them.

Doubts about the MOP's effectiveness prompted the Pentagon this month to secretly submit a request to Congress for funding to enhance the bomb's ability to penetrate deeper into rock, concrete and steel before exploding, the officials said.

The push to boost the power of the MOP is part of stepped-up contingency planning for a possible strike against Iran's nuclear program, say U.S. officials.

The Defense Department has spent about $330 million so far to develop about 20 of the bombs, which are built by Boeing Co. The Pentagon is seeking about $82 million more to make the bomb more effective, according to government officials briefed on the plan.

Some experts question if any kind of conventional explosives are capable of reaching facilities such as those built deep underground in Iran. But U.S. defense officials say they believe the MOP could already do damage sufficient to set back the program.

Defense Secretary Leon Panetta, in an interview with The Wall Street Journal Thursday, acknowledged the bomb's shortcomings against some of Iran's deepest bunkers. He said more development work would be done and that he expected the bomb to be ready to take on the deepest bunkers soon.

"We're still trying to develop them," Mr. Panetta said.
