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.

And American carriers never operate alone, it's a whole Carrier Battle Group there.

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.

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.

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.

Maybe stupid question but how would Iran do it? They don’t have any ships in the area and also don’t have any satellites that could take pictures, right? Or does getting told by Russia count?

Yes, Russia helps Iran target our troops and (likely) sailors.

But don't you dare suggest that hanging a portrait of Putin in the White House is inappropriate, or a Republican might get mad.

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 through south america and the north pole on its way there to avoid detection. Is what I'm saying something sci-fi?

Many countries do not have ready access to satellite imagery, much less realtime satellite imagery. Iran, for example.

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

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

>> 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…

Iran has their own satellites. They are also allied with Russia that has satellites and launch capabilities.

You would only need to find it once, potentially at a port, and then you can follow it.

This capability is available only to few countries on planet. Not all of them.

I admit I'm incredibly naive on this subject, but what makes it so hard to track an object as large as an aircraft carrier when starting from a known position such as a naval port?

If Charles de Gaulle turns off AIS, how does North Korea find it?

What's funny is I can imagine the sailor not understanding how the code works and properly setting up a "privacy zone" while at port to mask his location and verifying it was working while there

then of course while at sea, it's the same ship but different location

not like your home or workplace typically relocates itself

imagine being a coder at Strava trying to figure out how to deal with that, it's techically not possible

However it's a great marketing opportunity for Stryd footpod which can track distance without GPS

I wonder what a moving deck at even 10mph would do to a Stryd though

The GPS must have added 10mph? But it's all relative to the deck vs the sea, hmm
