Prompt Global Strike - U.S. Faces Choice on New Weapons for Fast Strikes

Via NYTimes -

In coming years, President Obama will decide whether to deploy a new class of weapons capable of reaching any corner of the earth from the United States in under an hour and with such accuracy and force that they would greatly diminish America’s reliance on its nuclear arsenal.

Yet even now, concerns about the technology are so strong that the Obama administration has acceded to a demand by Russia that the United States decommission one nuclear missile for every one of these conventional weapons fielded by the Pentagon. That provision, the White House said, is buried deep inside the New Start treaty that Mr. Obama and President Dmitri A. Medvedev signed in Prague two weeks ago.

Called Prompt Global Strike, the new weapon is designed to carry out tasks like picking off Osama bin Laden in a cave, if the right one could be found; taking out a North Korean missile while it is being rolled to the launch pad; or destroying an Iranian nuclear site — all without crossing the nuclear threshold. In theory, the weapon will hurl a conventional warhead of enormous weight at high speed and with pinpoint accuracy, generating the localized destructive power of a nuclear warhead.

The idea is not new: President George W. Bush and his staff promoted the technology, imagining that this new generation of conventional weapons would replace nuclear warheads on submarines.

In face-to-face meetings with President Bush, Russian leaders complained that the technology could increase the risk of a nuclear war, because Russia would not know if the missiles carried nuclear warheads or conventional ones. Mr. Bush and his aides concluded that the Russians were right.

Partly as a result, the idea “really hadn’t gone anywhere in the Bush administration,” Defense Secretary Robert M. Gates, who has served both presidents, said recently on ABC’s “This Week.” But he added that it was “embraced by the new administration.”

Mr. Obama himself alluded to the concept in a recent interview with The New York Times, saying it was part of an effort “to move towards less emphasis on nuclear weapons” while insuring “that our conventional weapons capability is an effective deterrent in all but the most extreme circumstances.”

The Obama national security team scrapped the idea of putting the new conventional weapon on submarines. Instead, the White House has asked Congress for about $250 million next year to explore a new alternative, one that uses some of the most advanced technology in the military today as well as some not yet even invented.

The final price of the system remains unknown. Senator John McCain of Arizona, the ranking Republican on the Senate Armed Services Committee, said at a hearing on Thursday that Prompt Global Strike would be “essential and critical, but also costly.”
