TRACKING THE WEAPONS
Huge Cache of Explosives Vanished From Site in Iraq
By JAMES GLANZ, WILLIAM J. BROAD and DAVID E. SANGER
BAGHDAD, Iraq, Oct. 24 - The Iraqi interim government has warned the United States and international nuclear inspectors that nearly 380 tons of powerful conventional explosives - used to demolish buildings, make missile warheads and detonate nuclear weapons - are missing from one of Iraq's most sensitive former military installations.
The huge facility, called Al Qaqaa, was supposed to be under American military control but is now a no man's land, still picked over by looters as recently as Sunday. United Nations weapons inspectors had monitored the explosives for many years, but White House and Pentagon officials acknowledge that the explosives vanished sometime after the American-led invasion last year.
A Lost Stockpile
Two weeks ago, on Oct. 10, Dr. Mohammed J. Abbas of the Iraqi Ministry of Science and Technology wrote a letter to the I.A.E.A. to say the Qaqaa stockpile had been lost. He added that his ministry had judged that an "urgent updating of the registered materials is required."
A chart in his letter listed 341.7 metric tons, about 377 American tons, of HMX, RDX and PETN as missing.
The explosives missing from Al Qaqaa are the strongest and fastest in common use by militaries around the globe. The Iraqi letter identified the vanished stockpile as containing 194.7 metric tons of HMX, which stands for "high melting point explosive," 141.2 metric tons of RDX, which stands for "rapid detonation explosive," among other designations, and 5.8 metric tons of PETN, which stands for "pentaerythritol tetranitrate." The total is roughly 340 metric tons or nearly 380 American tons
Five days later, on Oct. 15, European diplomats said, the arms agency wrote the United States mission in Vienna to forward the Iraqi letter and ask that the American authorities inform the international coalition in Iraq of the missing explosives
Dr. ElBaradei, a European diplomat said, is "extremely concerned" about the potentially "devastating consequences" of the vanished stockpile.
Its fate remains unknown. Glenn Earhart, manager of an Army Corps of Engineers program in Huntsville, Ala., that is in charge of rounding up and destroying lost Iraqi munitions, said he and his colleagues knew nothing of the whereabouts of the Qaqaa stockpile.
Administration officials say Iraq was awash in munitions, including other stockpiles of exotic explosives.
"The only reason this stockpile was under seal," said one senior administration official, "is because it was located at Al Qaqaa," where nuclear work had gone on years ago.
As a measure of the size of the stockpile, one large truck can carry about 10 tons, meaning that the missing explosives could fill a fleet of almost 40 trucks.
By weight, these explosives pack far more destructive power than TNT, so armies often use them in shells, bombs, mines, mortars and many types of conventional ordinance.
"HMX and RDX have a lot of shattering power," said Dr. Van Romero, vice president for research at the New Mexico Institute of Mining and Technology, or New Mexico Tech, which specializes in explosives.
"Getting a large amount is difficult," he added, because most nations carefully regulate who can buy such explosives, though civilian experts can sometimes get licenses to use them for demolition and mining.
An Immediate Danger
A special property of HMX and RDX lends them to smuggling and terrorism, experts said. While violently energetic when detonated, they are insensitive to shock and physical abuse during handling and transport because of their chemical stability. A hammer blow does nothing. It takes a detonator, like a blasting cap, to release the stored energy.
Experts said the insensitivity made them safer to transport than the millions of unexploded shells, mines and pieces of live ammunition that litter Iraq. And its benign appearance makes it easy to disguise as harmless goods, easily slipped across borders.
"The immediate danger" of the lost stockpile, said an expert who recently led a team that searched Iraq for deadly arms, "is its potential use with insurgents in very small and powerful explosive devices. The other danger is that it can easily move into the terrorist web across the Middle East."
More worrisome to the I.A.E.A. - and to some in Washington - is that HMX and RDX are used in standard nuclear weapons design. In a nuclear implosion weapon, the explosives crush a hollow sphere of uranium or plutonium into a critical mass, initiating the nuclear explosion.
A crude implosion device - like the one that the United States tested in 1945 in the New Mexican desert and then dropped on Nagasaki, Japan - needs about a ton of high explosive to crush the core and start the chain reaction.Full Story (http://www.nytimes.com/2004/10/25/international/middleeast/25bomb.html?th)
