PARIS — France is taking appropriate measures after a naval officer's use of the Strava exercise app enabled journalists to geolocate the Charles de Gaulle in the Mediterranean. On March 13, a naval officer used the Strava exercise app during a morning jog.

A French newspaper used Strava data to locate a naval officer and reporters used a satellite image taken on the same day to locate the Charles de Gaulle in the Mediterranean. A French newspaper said it believes the officer was jogging on the Charles de Gaulle or one of its escort ships.

Col. Guillaume Vernet, a French military spokesman, said the reported use of the Strava app by a naval officer does not comply with current guidelines. "In the course of their duties, sailors are regularly made aware of the security risks associated with connected devices, the use of social media in their private lives and the potential for geolocation through digital applications," Vernet said.

"To prevent any disclosure of information relating to a vessel, different levels of restrictions on the use of connected devices are applied within the French navy. These levels of restriction are determined by the command, depending on the level of threat," he said.

On March 13, Rear Adm. Thibault Haudos de Possesse, commander of the aircraft carrier group, briefed reporters in a video call from aboard the Charles de Gaulle. The carrier was escorted by multiple warships, including French and allied-nation frigates.

The Charles de Gaulle was carrying 20 Rafale fighter jets, two Hawkeye surveillance planes and three helicopters. The deployment of the Charles de Gaulle in the Mediterranean this month was not secret.

The Charles de Gaulle is a nuclear-powered aircraft carrier with a displacement of 42,000 tons and a length of 261 meters (856 feet).

A French newspaper said that divulging the carrier strike-group's location almost in real time on a public digital platform is dangerous as the Iran war continues.
