U.S. erred on nuke delivery (Detroit Free Press)

"The U.S. military mistakenly shipped four nuclear-missile detonators to Taiwan in 2006, then failed to detect the error for more than a year, the Pentagon admitted Tuesday.

The incident raises concerns about relations with China, which already opposes U.S. arms sales to Taiwan. China claims the self-governing island as its own and has threatened to attack if Taiwan makes its independence formal.

Also, this was the second time in recent months that Pentagon officials acknowledged losing track of parts of the country's nuclear arsenal. Last September, a B52 bomber was mistakenly loaded with nuclear-armed missiles and flown across the United States to a military base in Louisiana. At the time, Pentagon leaders called the incident isolated.

The fuses mistakenly sent to Taiwan had been shipped in March 2005 from Warren Air Force Base in Wyoming to the Defense Logistics Agency warehouse at Hill Air Force Base in Utah.

Pentagon officials said they didn't know how the detonators had been sent when Taiwan had ordered helicopter batteries, or who was responsible."
