Boeing Company has won an order valued at $324 million to provide France with a mid-life upgrade of its Airborne Warning and Control System (AWACS), the Pentagon said.

The E-3 AWACS Sentry aircraft is based on a Boeing 707 airframe and is used by the United States, Britain, France, NATO and Saudi Arabia.

The Pentagon informed Congress about the possible AWACS sale to France in September 2008 as part of an effort to maintain full interoperability with U.S. and other NATO coalition partners.
