Officer Leaks Location of French Aircraft Carrier With Strava Run (bbc.com) 86

schwit1 shares a report from the BBC: A French officer has reportedly revealed the location of an aircraft carrier deployed towards the Middle East after publicly registering a run on sports app Strava. French news outlet Le Monde first reported the officer, referred to as Arthur, logged a 35-minute run on the app while exercising on the deck of aircraft carrier Charles de Gaulle on 13 March. He used a smartwatch to record his run and upload the activity to the app, the paper said, creating a map that showed his location. [...] The location of the vessel was said by Le Monde to have been northwest of Cyprus, around 100km (62 miles) from the Turkish coast, with satellite images capturing the carrier and its escort. A representative from the French Armed Forces said the officer's behavior "does not comply with current guidelines," which "sailors are regularly made aware of."

    Does anyone seriously think that any country that might have an interest in the location of that ship doesn't already know exactly where it is?
    • This. Isn't the point of an Aircraft Carrier to establish dominance? It isnt a surprise attack vessel. When a carrier strike group moves into your neighborhood, you know. They want you to know.

      Yes. Actors with interest here is Iran and its proxies, and their reconnaissance capabilities are exceedingly oversubscribed right now. Whatever access to reconnaissance data they still have, they're most certainly going to be very grateful for narrowing down the scope of the search.

      The primary defense of the aircraft carrier is to hide at the sea, and stay highly mobile, making long range targeting by ballistics impossible. For those not in the know, most anti-ship ballistic missiles are targeted at an area, and fire up their radar only after they're quite a while into the descent, meaning you need to know approximate location of the carrier group for ballistic anti-shipping missiles to have any effect on them. Otherwise it just arrives in the area, and there's nothing within range of its radar because carrier group is long gone from last reconnaissance data. Or even worse, there's another group of vessels in the area missile locks on to and hits, and it has nothing to do with the conflict. Which Iran and its proxies have been doing for years.

      So this not only put the carrier group in danger, it also put civilian shipping in the area in danger. Massive fuck up.

        Good luck hiding something the size of an aircraft carrier in the busy meditterenean. Its probably seen by the the crews of dozens of ships every day.

        • by Luckyo ( 1726890 )

          It's exceedingly easy, because this data is exceptionally time sensitive. Assume extreme red capability, i.e. say missile can track targets within 50km radius upon arrival in the sector and has perfect accuracy with its inertial system and faces zero degradation from EW assets.

          Carrier groups are generally rated to travel at around 30 knots combat and aircraft launch speeds. Let's assume it's going with oilers and not conducting active operations, so it's probably going to be as low as 20kn.

          So this slow ass

      • This are not "ballistic" missiles but "cruise" missiles.

        Ballistic means, you shoot in an arc, and it gets down in an area where the end of the shot is.

        Close to that end, ofc. you could use radar and fins and rockets to adjust your drop down.

        Typical anti ship missiles are ground/sea level hovering low flying (the opposite to ballistic) missiles, which indeed switch on radar on the last moment.

        • by Luckyo ( 1726890 )

          Cruise missiles lack range needed for this sort of work, are unsuitable due to being far too slow at those ranges, and finally as Ukraine war has shown are exceedingly vulnerable against any fast jet assets.

          This is why Russian anti-carrier group strike asset package involved massive wings of supersonic bombers firing dozens to hundreds of such missiles into a single carrier group from a fairly close range and very high altitude and speed.

          • I pointed out that you used the word "balistic" wrong.

            No idea about the other points.

            No idea about Russian tactics. Anti ship missiles like Exocet touch surface as soon as possible and approach the target in a height around 10m ...

            • by Luckyo ( 1726890 )

              As usual, you're wrong on everything.

              Long range cruise missiles fly high to conserve energy most of the flight, and only go low once they get close enough to were they can afford to lose energy flying in much denser atmosphere.

              Exocets are short range cruise missiles. They're utterly unsuitable for Iran to attack anything in the Med. They're barely suitable for working in the Gulf from Iran's perspective, as even there, they wouldn't be able to reach many places without exposing the launcher.

              Almost all long

                And last post you claimed cruise missiles are not used for attacks in ships. Now you claim they are.

                Make up your mind.

                An Exocet is not a cruise missile, it is a farking rocket. Get your terms right.

                Almost all long range anti-shipping missiles of the kind that Iran could use to attack shipping in the med are ballistic.

      • Even if what you said is true, no one is sitting around scouring Strava for locations of aircraft carriers to launch ballistic missiles. If the carrier is moving then the same theory still applies, not a massive risk.

        Also it's trivial to locate an aircraft carrier group close to your country. This isn't a small strike force.

          As for the rest, Luckyo already said it. As a former carrier TAO, s/he's right. Targeting data is ridiculously time sensitive because your circle of error probable [wikipedia.org] falls off spectacularly and is compounded by modern carrier tactics.

                      an aircraft carrier isn't much of a "rapidly moving target" and in this case doesn't need to be tracked all the way across the ocean; the enemy only needs to know when it's within effective range.
                      but figuring out its location can be as simple as having someone ask the right person a simple question
