Rockwell International Corp. has denied concealing low subcontractor bids during contract negotiations with Hill Air Force Base's Ogden Air Logistics Center.

A 1988 report by the federal General Accounting Office contends that Rockwell overcharged the Air Force by more than $1 million in a $38 million contract for supplying seven parts for the GBU-15 guided bomb.The report says Rockwell failed to inform the Air Force of updated, lower supplier prices for three of the parts while concluding the deal, as required by the Truth in Negotiations Act, the GAO said.

In a prepared response Friday, Rockwell spokesman Vince Vinci said Rockwell International's Missile Systems Division denies the GAO's allegations made during congressional testimony Sept. 7.
