PARIS — Dutch regional broadcaster Omroep Gelderland was able to track the Royal Netherlands Navy air-defense frigate Evertsen in real time by sending a Bluetooth tracker to the ship by military mail. The frigate is part of the carrier strike group around France’s Charles de Gaulle aircraft carrier currently deployed in the Mediterranean Sea.
The tracker was discovered while sorting mail on board, though only after Omroep Gelderland had been tracking the Evertsen for 24 hours, the broadcaster wrote on its website on Thursday. The Dutch Ministry of Defence said it’s taking measures in response, according to the broadcaster.
The tracker incident comes after a Le Monde reported in March it was able to locate a French officer taking a 7-kilometer run around the deck of the Charles de Gaulle while the carrier was at sea, through data from the officer’s connected watch via the running and cycling app Strava.
“You do want to be able to intercept such a tracker,” Rowin Jansen, assistant professor of national security law at Radboud University in Nijmegen, told Omroep Gelderland. “Commercial satellite images are currently released with a delay for good reason. You certainly don’t want to make it easy for terrorists to send a similar package and track a ship’s location in real time. You then run the risk of having missiles fired at you.”
The broadcaster described sending the Bluetooth tracker, a gadget used for example to find keys, to the frigate in an envelope using the military postal service, following online instructions from the MoD on how to send mail to military personnel.
While the ministry checks whether prohibited or dangerous items are sent by mail by X-ray scanning packages, Omroep Gelderland noted that online videos showed envelops not being scanned, so decided to pack the tracker in a postcard, with the gadget going undetected and simply mailed.
“In a large-scale conflict, everyone needs to ask themselves: What can I contribute to the safety of our men and women?” said retired Lt. Gen. Mart de Kruif, as cited by the broadcaster. “So you should no longer rely on existing rules, but on what is necessary. We’re still a bit naive, and that mindset needs to change.”
Omroep Gelderland mapped the route of the tracker from the Dutch naval base in Den Helder to Eindhoven Airport, and then on to the port of Heraklion in Crete, where webcam images showed the Evertsen moored at the quay.
With the frigate departing the port on March 27, the broadcaster said it was able to track the vessel sailing west along the coast of Crete before setting an eastward course. The tracker then went permanently offline 24 hours later near Cyprus, it said.
The MoD has made adjustments in response to the reported incident, including no longer allowing greeting cards with batteries to be sent to the Evertsen, and the ministry will further review the guidelines for military mail, a spokesperson told Omroep Gelderland.
The tracker was found during mail sorting aboard the frigate after it set sail, and while the vessel could be tracked at sea, this would not have posed an operational risk, according to the MoD.
Defence Minister Dilan Yeşilgöz informed parliament about the incident on Thursday evening, Omroep Gelderland said.
