I would have thought so too but Naval Gazing has a short series [0] on why it's not as dire as one might think. An aircraft carrier's location being "secret" in this case is just one layer of the survivability onion [1] anyhow. (Caveat that as someone who takes a casual interest in this, I can't vouch for accurate this is at all.) [0] https://www.navalgazing.net/Carrier-Doom-Part-1 [1] https://www.goonhammer.com/star…

Not hidden from nation states with access to real-time satellite imagery, but more rustic guerilla operations usually don't have such sophisticated access

Just poor ones - how much could it cost to get a scan of the oceans once weekly or daily? 10 million dollars?

Seems we need a new digital category for Darwin Awards. This is the modern way to die of stupidity — use your fitness watch app to log your miles on an online app instead of locally — so reveal your operational location. The US had one of its secret bases in Afghanistan fully mapped for anyone to see by its residents logging their on-base runs. Now, the French aircraft carrier is pinpointed en route to a war zone. Ye…

No amount of OPSEC lectures or packet inspection is going to sufficiently keep the carrier's private information private. There's thousands of sailors on these things. When details like its location and readiness level actually need to be secret, all regular internet access should just be cut off. Radio silence. I assume this person had internet access to use Strava because the carrier isn't yet in some higher level of readiness and its location isn't yet considered much of a secret.

Cruising speed of Charles de Gaulle is 27knots which would give the runner a pace of around 1:10mins/km depending on direction. That would really screw up your Strava stats

I occasionally see civilians on Strava doing the same thing, running laps around the deck of a cruise ship. The speeds and distances look ridiculous.

101 assumptions programmers make about running apps.

Mediterranean maybe (although I'm not sure), but it's actually very hard to find a ship, even as large as an aircraft carrier, in the ocean. The empty space is just too big. Satellites have hard time taking pictures of every square mile of a sea to find any ship, yet alone the one you need.

Ships are giant hunks of metal and radio emitters. They light up on SAR satellites[0]. Sentinel-1 gets whole earth coverage and a revisit time of 1-3 days[1] with two active satellites. And that's the public stuff, if you can afford a fleet or even some extra fuel to steer them into interesting orbits you can get faster revisits.

There is a french company (https://unseenlabs.com/fr/) that specializes in tracking ship at sea through observing their RF emission from space. Cool tech. I'm pretty sure their main clients are not all civil...

Tracking an aircraft carrier should not be difficult for any state (satellite images). The fact that civilians can do it too now is interesting. It would be another matter if that was tracking a nuclear submarine...

No, this is notoriously difficult. The earth is vast and a carrier is tiny in comparison.

Err, no. The consensus and available evidence including washed up components seems to be that it crashed in the Indian Ocean, that's the (also vast) space between ~Australia and ~Africa, bounded in the north by Indonesia, the Indian subcontinent, and Arabia. It crashed somewhere in the eastern portion, not far from Indonesia and Australia. Currents then took parts as far as the Maldives/Sri Lanka, IIRC. The Pacific i…

Are you making the same point as the person you said "err, no" to, or are you correcting the inconsequential details while not addressing their main point?

No. literalAardvark's main statement, "[It] crashed in the Pacific," was incorrect. contingencies's comment corrected that.

Aircraft carrier speed... 33 knots or about 35mph[1] Boeing 777 speed 554mph[2] So about 16x! [1] http://www.navweaps.com/index_tech/tech-028.php [2] https://en.wikipedia.org/wiki/Boeing_777

Honestly pretty crazy, although that must be the max speed. The carrier was going about 10 mph in this case (per Strava).

They don't normally go that fast from what I understand. That is their top speed in reserve they can use for evasive maneuvers, they don't want to go faster than their support fleet or deal with the high maintenance running at threshold will cause.

It's like when you drive your car you're not normally redlining it since that will kill the engine if you do it all the time.

To be fair, I would assume that the base, or in this case the carrier, is the only place where they would have the reception to broadcast their location, right? You probably don’t have cell service while out and about planting weapons on massacred civilians.

Typically you'd record your run with GPS, no need for cell service, sync it to your devices occasionally and that's when it might be uploaded, or later.

Not every damn thing needs to be “social”.
