Missteps in the Bunker
Sunday, September 23, 2007; Page A01
Just after 9 a.m. on Aug. 29, a group of U.S. airmen entered a sod-covered bunker on North Dakota's Minot Air Force Base with orders to collect a set of unarmed cruise missiles bound for a weapons graveyard. They quickly pulled out a dozen cylinders, all of which appeared identical from a cursory glance, and hauled them along Bomber Boulevard to a waiting B-52 bomber.
The airmen attached the gray missiles to the plane's wings, six on each side. After eyeballing the missiles on the right side, a flight officer signed a manifest that listed a dozen unarmed AGM-129 missiles. The officer did not notice that the six on the left contained nuclear warheads, each with the destructive power of up to 10 Hiroshima bombs.
That detail would escape notice for an astounding 36 hours, during which the missiles were flown across the country to a Louisiana air base that had no idea nuclear warheads were coming. It was the first known flight by a nuclear-armed bomber over U.S. airspace, without special high-level authorization, in nearly 40 years.
The episode, serious enough to trigger a rare "Bent Spear" nuclear incident report that raced through the chain of command to Defense Secretary Robert M. Gates and President Bush, provoked new questions inside and outside the Pentagon about the adequacy of U.S. nuclear weapons safeguards while the military's attention and resources are devoted to wars in Iraq and Afghanistan.
Three weeks after word of the incident leaked to the public, new details obtained by The Washington Post point to security failures at multiple levels in North Dakota and Louisiana, according to interviews with current and former U.S. officials briefed on the initial results of an Air Force investigation of the incident.
The warheads were attached to the plane in Minot without special guard for more than 15 hours, and they remained on the plane in Louisiana for nearly nine hours more before being discovered. In total, the warheads slipped from the Air Force's nuclear safety net for more than a day without anyone's knowledge.
"I have been in the nuclear business since 1966 and am not aware of any incident more disturbing," retired Air Force Gen. Eugene Habiger, who served as U.S. Strategic Command chief from 1996 to 1998, said in an interview.
A simple error in a missile storage room led to missteps at every turn, as ground crews failed to notice the warheads, and as security teams and flight crew members failed to provide adequate oversight and check the cargo thoroughly. An elaborate nuclear safeguard system, nurtured during the Cold War and infused with rigorous accounting and command procedures, was utterly debased, the investigation's early results show.
The incident came on the heels of multiple warnings -- some of which went to the highest levels of the Bush administration, including the National Security Council -- of security problems at Air Force installations where nuclear weapons are kept. The risks are not that warheads might be accidentally detonated, but that sloppy procedures could leave room for theft or damage to a warhead, disseminating its toxic nuclear materials.
A former National Security Council staff member with detailed knowledge described the event as something that people in the White House "have been assured never could happen." What occurred on Aug. 29-30, the former official said, was "a breakdown at a number of levels involving flight crew, munitions, storage and tracking procedures -- faults that never were to line up on a single day."
Missteps in the Bunker
The air base where the incident took place is one of the most remote and, for much of the year, coldest military posts in the continental United States. Veterans of Minot typically describe their assignments by counting the winters passed in the flat, treeless region where January temperatures sometimes reach 30 below zero. In airman-speak, a three-year assignment becomes "three winters" at Minot.
The daily routine for many of Minot's crews is a cycle of scheduled maintenance for the base's 35 aging B-52H Stratofortress bombers -- mammoth, eight-engine workhorses, the newest of which left the assembly line more than 45 years ago. Workers also tend to 150 intercontinental ballistic missiles kept at the ready in silos scattered across neighboring cornfields, as well as hundreds of smaller nuclear bombs, warheads and vehicles stored in sod-covered bunkers called igloos.
