Congressional review faults USAF decision to award tanker contract to EADS/Northrop

Washington/Paris: The EADS/Northrop combine took a heavy blow yesterday when the Government Accountability Office (GAO), a review arm of the US Congress, urged the US Air Force (USAF) to reopen the $35bn (£18bn) refuelling tanker deal which it had awarded to the combine.

The GAO agreed with Boeing, the losing contender, that there were flaws in the process that resulted in the EADS/Northrop Grumman aircraft being selected in preference to the one offered by Boeing.

The GAO report stressed that its decision focused on the errors in the selection process and was not an assessment of the merits of the two aircraft competing to replace the USAF's fleet of ageing tankers. According to GAO officials, the USAF made "significant errors" that could have affected the outcome of a very close competition, including flawed cost assessments.

Though the GAO ruling is not legally binding, the USAF has committed itself to following any recommendation made by it. It said yesterday that it was reviewing the decision. It has 60 days to respond to the GAO findings.

The USAF tanker contract is likely to be one of the biggest contracts in Pentagon history, potentially worth $100 billion with follow-on orders. The current $35 billion deal was to build 179 midair refuellers over the next 15 years which would have replaced the USAF's current fleet of Boeing KC-135 tankers.

The fleet, on an average, is 47 years old.
