As the second Iraq war loomed and created new chemical weapons threats, Air Force commanders in the Middle East heard that the Pentagon was developing a new hand-held chemical agent detector said to be better than equipment they were using.

So they begged in late 2002 for 100 early models to be bought and sent to them.

Officials complied, at a total cost of $1 million. Trouble is, they knew manufacturer's tests showed the detectors didn't work well in hot areas or under battle conditions. And they didn't wait for other planned tests, including some at Utah's Dugway Proving Ground, which would conclude that the equipment is not worth purchasing until it is improved significantly.

So, a Defense Department Inspector General report says the Air Force not only wasted $1 million on unreliable detectors, but it may have put airmen at increased risk while they depended on the equipment. The report says officials appear to have violated a variety of federal laws and military rules to do that.

The Pentagon also ordered the Air Force to cease using the 100 detectors that were bought and to collect and return them to military testers working on improving them.

The information is in documents obtained by the Deseret Morning News through a Freedom of Information Act request.

Inspector general documents say the military began developing a new hand-held chemical arms detector after the first war in Iraq, when "a major deficiency identified was the inability of U.S. forces to effectively detect and identify chemical warfare agents."

British Aerospace Systems was chosen as the contractor to develop a "joint chemical agent detector." After the 9/11 terrorist attacks, that company also began marketing a virtually identical commercial version called the "JCAD ChemSentry."

Amid such marketing, the inspector general report says, Air Force Central Command overseeing the Middle East erroneously "perceived that the JCAD ChemSentry technology provided greater operational capacity than the capabilities of fielded detectors" it was already using.

The command filed an "Unusual and Compelling Urgency Need" request asking officers who oversee development of the detector to buy and send 100 models. When told it would take three months to verify that need, Air Force commanders said that was unacceptable and that they would buy commercial versions directly from the manufacturer.

In response, the military's JCAD Program Office decided to go ahead and buy the requested detectors quickly. But instead of purchasing them as part of its normal programs to test and verify the early military version, it opted also to buy the commercial model instead.
