United Technologies (UTC) has been ordered to pay $473 million plus interest to the US government for making false claims and overcharging on military engines.

The lawsuit concerns claims made about Pratt & Whitney F100 engines used to power Boeing F-15s and Lockheed Martin F-16s.

According to the US Department of Justice, UTC subsidiary P&W overcharged the military from 1985 to 1990 because the company "inflated its estimated costs for some purchased parts and withheld data that would have revealed the overstatements".

The case has been ongoing since 1999. In 2004, a federal judge found against P&W and fined it $624 million, which P&W appealed. In 2008, another judge found P&W liable for $84 million, which P&W and the US government both appealed.

UTC announced its intention to appeal the latest ruling as well. Neither UTC nor the Department of Justice responded to immediate questions.
