Air Force Tests 'Mother of All Bombs'

The Air Force dropped its largest non-nuclear bomb on a test range in Florida Tuesday, sending Saddam Hussein a powerful message about the weaponry Iraq would face in a possible war.

The 21,000-pound explosive is officially known as the Massive Ordnance Air Blast, or MOAB. Unofficially, the weapon has been dubbed the Mother of all Bombs, a reference to Saddam Hussein's claim before the 1991 Gulf War that that conflict would be the "mother of all battles."

Cheryl Irwin, a Pentagon spokeswoman, said the test was successful.

"It did what they expected it to do. Nothing malfunctioned," she said.

Neither Gen. Richard Myers nor Defense Secretary Donald Rumsfeld would say whether the MOAB would be used in a possible war with Iraq.

"Anything we have in the arsenal, anything that's in almost any stage of development, could be used," Myers said.

The Air Force also didn't offer details on how MOAB might be used. John Pike, a defense analyst with, said Tuesday it might be useful against Iraqi Republic Guard formations or even targets around Baghdad such as one of Saddam's palaces.

Rumsfeld suggested that the bomb, which was dropped out the back of a C-130 transport plane over a test range at Eglin Air Force Base, Fla., was also useful as a psychological weapon.

"The goal is to not have a war," he said. "The goal is to have the pressure be so great that Saddam Hussein cooperates. Short of that ... the goal is to have the capabilities of the coalition so clear and so obvious that there is an enormous disincentive for the Iraqi military to fight against the coalition and there's an enormous incentive for Saddam Hussein to leave and spare the world a conflict."

A Pentagon official who had seen video footage of the test said the bomb produced a tall cloud of debris that billowed into the sky but did not resemble the mushroom-shaped cloud of an atomic explosion.

Some area residents felt the bomb's detonation but said the explosion was not as big as they had expected.

"It was kind of weak," said Patricia Sariego, a receptionist at the Best Western hotel in Navarre, on the southern edge of Eglin. She added that the blast shook doors.

On the diplomatic front, the United States and Britain faced the prospect of defeat for their U.N. resolution giving Iraq until Monday to comply with disarmament demands. It appeared the countries might agree to a short extension of the deadline.

Rumsfeld even suggested that Britain's participation in combat was in doubt, but later he appeared to back away from that idea.

"Until we know what the resolution is (going to say), we won't know the answer as to what their role will be," Rumsfeld said of the British military, which is deploying 45,000 troops to the Gulf.

"And to the extent they are able to participate -- in the event that the president decides to use force -- that would obviously be welcomed," he added. "To the extent they're not, there are work-arounds and they would not be involved, at least in that phase of it."

Asked whether that meant the United States was mulling an invasion of Iraq without Britain, he said, "That is an issue that the president will be addressing in the days ahead, one would assume."

Later, after reports that British officials were surprised by his words, Rumsfeld's office issued a written statement stressing his main point in the news conference was that Britain supported obtaining a second U.N. resolution and that both countries were working to achieve it.

"In the event that a decision to use force is made, we have every reason to believe there will be a significant military contribution from the United Kingdom," Rumsfeld's statement said.

British Prime Minister Tony Blair faces enormous public opposition to his stance in support of Bush.

In London, Blair's office told The Associated Press: "This does not change anything. We are still working for a second resolution. We are not at a state of military combat but there has been complete cooperation between the United Kingdom and the United States throughout on the military planning side."

The U.S. commander who would lead a war against Iraq, Gen. Tommy Franks, met in Amman, Jordan, with King Abdullah II on Tuesday. Franks' office was releasing few details about his schedule, although officials said he was headed to Afghanistan to visit U.S. troops and then to the Persian Gulf. His last stop will be his Gulf command post at Camp As Sayliyah, Qatar.

Over Iraq, two American U-2 surveillance planes flying on behalf of U.N. weapons inspectors aborted their missions after Iraq raised objections. There were conflicting reports on the circumstances. An Iraqi official described the incident as a "technical mistake" by the U.N inspectors; Pentagon officials said it was too early to know who was to blame.

At a joint news conference with Rumsfeld, Gen. Richard Myers, chairman of the Joint Chiefs of Staff, said the number of American forces now arrayed against Iraq exceeded 225,000 and more were en route.
