I seriously doubt there is a country on earth which lacks the capability to detect an aircraft carrier's presence in the Mediterranean sea. We are not talking about stealth vehicles.

We couldn’t find a commercial jet (MH370). Both, while it was still flying in the air and after it was presumably lost in the ocean. They couldn’t track it in the air nor can they still find its remains after looking for it for so long. This problem is not trivial.

There's a nonzero chance military intelligence agencies of multiple countries know exactly where that plane fell, but none can say anything, because that would reveal the true extent of their capabilities.

The Indian Ocean is both larger and has significantly less traffic than the Mediterranean. And a 777 is about 16x faster than a carrier.

It's pretty hard to hide it from anything . Its surface is ~17000 m² (a tennis court is ~260 m²), and is 75 m high (~ 25 floors building - probably half of it under water, but still). And that's a mid-sized carrier according to Wikipedia. It's not built for hiding at all, that's what submarines are for (and that's where our nukes are).

But the ocean is very very huge to find it still.

Am I supposed to believe we live in a world where this exists, yet carriers are impossible to find and track on the sea?

Besides, modern fighter jets have radars with 400km detection ranges against fighter sized targets.

A dozen of them or more specialized sensor aircraft could cover entire conflict zones.

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.

>Satellites have hard time taking pictures of every square mile of a sea to find any ship, yet alone the one you need. That's why satellites use radars and scientific instrumentation magnetometers to find stuff like ships or even subs underwater.

There might be some secret technology that we're unaware of but as far as we know magnetometers can only be used to detect underwater targets at very short ranges. I highly doubt that they're used on military reconnaissance satellites.

Those suffer from the same problem. There's a lot of ocean, and if you don't know where to look then you won't find what you're looking for.

>if you don't know where to look I mean fuck, I can pretty easily find the strait of hormuz on the map, pretty sure intelligence agencies can too and just look there for the carrier. If I can't find the carrier there, then I can plot the course between France and hormuz and do a brute force search over that course taking into account such a ship's relative velocity, since it's not like the carrier is gonna zig-zag th…

Seems to have come as a shock to the US government.

Is an aircraft carrier's location supposed to be secret? Pretty hard to hide from a satellite I'd imagine.

It’s like trying to find someone you see in a street view image from a maps provider. The data will always be at least an hour old and that’s a hundred times as long as it takes for the person to be impossibly labor-intensive to find. Carriers are easier to find once you’re on the ocean in close proximity than someone in a city is, but then so are you — and the carrier has armed warplanes whose job is to prevent you…

Are we talking about Strava, or satellites? It's not obvious to me that exercise data is any more real time or easy to find than satellite tracking.

Shots across the bows are a pretty universal signal.
