France's aircraft carrier located in real time by Le Monde through fitness app

>> Pretty hard to hide from a satellite I'd imagine.

Clouds. (Radar sats can see through clouds but can also be jammed.)

But even on a clear day, most of the people looking to target a carrier these days (Iran/hamas etc) don't have their own satellites. But a real-time GPS position accurate to few meters? That could be tactically useful to anyone with a drone.

An active fitness tracker might also give away the ship's readiness state, under the assumption that people aren't going to be doing much jogging while at battle stations.

This is a common problem across militaries. It is difficult to stop soldiers from leaking their location if they have access to mobile phones and the Internet. Individual cases are usually a combination of naïveté, ignorance, and an unwillingness to be inconvenienced.

It still happens in Ukraine, where immediate risk to life and limb is much more severe than this case.

Iran is being fed intelligence by Russia, so they definitely have that info.

I kind of understand that, although of course i completely disagree with their line of thinking. Iran is everyones problem and open conflict like this would have been hard to avoid down the road. Point is they had months to anticipate this latest conflict, why did they do absolutely nothing to mitigate this? Why was the UK apparently completely unprepared? Europe's economy is suffering, more then America. Why do we even bother with a Navy if we don't wan't to use it?

Also what military support did they drop exactly? Ukraine isn't part of NATO, and the US has been carrying 90% of NATO since forever. I will point out that it was the US, through a combination of bombing and diplomacy that got rid of the Houthi threat to shipping. Nobody else succeeded.

> It's not a declaration of war to project your military power to a region you have an interest in.

There was no declaration of war by anyone so far, and I doubt Iran would wait for an official letter telling them they're allowed to sink a US allied carrier, especially now that they killed the leader's wife, son, dad, and a bunch of relatives (plus the only dude who the US could reasonably negotiate with)
