Defense News – Western navies are preparing for wartime scenarios where they may face degraded operational conditions, including a loss of satellite communications, navy commanders from the U.S. and France said at the Paris Naval Conference this week. The French navy includes two or three days of drills under “back to the ‘80s” conditions whenever it deploys its carrier strike group, which means operating without satellite communications, Navy Chief of Staff Adm. Nicolas Vaujour said at the conference.
