Pentagon eyes accelerated “bunker buster” bomb

WASHINGTON, (Reuters) – The Pentagon is seeking to  speed deployment of an ultra-large “bunker-buster” bomb on the  most advanced U.S. bomber as soon as July 2010, the Air Force  said yesterday, amid concerns over perceived nuclear threats  from North Korea and Iran.

The non-nuclear, 30,000-pound Massive Ordnance Penetrator,  or MOP, which is still being tested, is designed to destroy  deeply buried bunkers beyond the reach of existing bombs.

If Congress agrees to shift enough funds to the program,  Northrop Grumman Corp radar-evading B-2 bomber “would be  capable of carrying the bomb by July 2010,” said Andy Bourland,  an Air Force spokesman.

“The Air Force and Department of Defense are looking at the  possibility of accelerating the program,” he said. “There have  been discussions with the four congressional committees with  oversight responsibilities. No final decision has been made.”

The precision-guided weapon, built by Boeing Co, could  become the biggest conventional bomb the United States has ever  used.
Carrying more than 5,300 pounds of explosives. it would  deliver more than 10 times the explosive power of its  predecessor, the 2,000-pound BLU-109, according to the  Pentagon’s Defense Threat Reduction Agency, which has funded  and managed the seed programme.

Chicago-based Boeing, the Pentagon’s No. 2 supplier by  sales, could be put on contract within 72 hours to build the  first MOP production models if Congress signs off, Bourland  said.

The threat reduction agency is working with the Air Force  to transition the program from “technology demonstration” to  acquisition, said Betsy Freeman, an agency spokeswoman.

Both the U.S. Pacific Command, which takes the lead in U.S.  military planning for North Korea, and the Central Command,  which prepares for contingencies with Iran, appeared to be  backing the acceleration request, said Kenneth Katzman, an  expert on Iran at the Congressional Research Service, the  research arm of Congress.

“It’s very possible that the Pentagon wants to send a  signal to various countries, particularly Iran and North Korea,  that the United States is developing a viable military option  against their nuclear programs,” Katzman said.

But he cautioned against concluding there was any specific  mission in mind at this time.
The MOP would be about one-third heavier than the  21,000-pound (9.5 million kg) GBU-43/B Massive Ordnance Air  Blast bomb — dubbed the “mother of all bombs” — that was  dropped twice in tests at a Florida range in 2003.

The 20-foot-long (6-metre) MOP is built to be dropped from  either the B-52 or the B-2 “stealth” bomber. It is designed to  penetrate up to 200 feet (61 metres) underground before  exploding, according to the U.S. Air Force.

The suspected nuclear facilities of Iran and North Korea  are believed to be largely buried underground to escape  detection and boost their chances of surviving attack.

During a visit to Jerusalem last week, U.S. Defense  Secretary Robert Gates sought to reassure Israel that a drive  by President Barack Obama to talk Iran into giving up its  nuclear work was not “open-ended.”

Iran says its uranium enrichment — a process with  bomb-making potential — is for energy only and has rejected  U.S.-led demands to curb the program.
For its part, North Korea responded to new United Nations  sanctions, imposed after it detonated a second nuclear device,  by vowing in June to press the production of nuclear weapons  and act against international efforts to isolate it.
