This is kinda cool. Two US Navy carriers imaged with synthetic aperture radar from space. I'm pretty sure this is Norfolk. Don't know the carriers, but it should not be too hard to figure them out.

That is indeed Naval Station Norfolk.

To be precise it is Pier 14.

The Carrier on Berth 14S (lefthand aircraft carrier) is the USS George Washington (CVN 73). She berthed here 13 Jan 2024 after 13 days at sea conducting FRS/TRACON qualification.

The other is USS Harry S Truman on berth 14N. She berthed here 23 Jan 2024 after a four days at sea for trials after an extended 14-month PIA (Planned Incremental Availability).

The aircraft carrier USS Dwight D. Eisenhower is missing from this photo because it is submerged.

These decoy silhouettes are supposed to fool automated visual recognition systems. I have my doubts.

Especially if there are systems which pair more than one look angle.

Meanwhile, I'd be curious what you could find carrier-wise with Bellingcat's marine offering ? https://www.bellingcat.com/resources/2023/05/11/peering-beyond-the-clouds-a-guide-to-bellingcats-ship-detection-tool/

At quick glance, this appears kinda alarming--somebody can use an American satellite to find the location of US Navy forces in the open ocean. Of course, this doesn't provide info on the exact location of the ships, and the US Navy knows that bad guys are looking for them. But it's again a testament to how readily available this technology has become.

A decently sized SAR constellation could track every ship in the ocean simultaneously in real time. Will have huge consequences for Naval warfare.
artist, so take opinions expressed above with a well-rendered grain of salt...

It'll be interesting to see if China expands its SAR system in GEO beyond a single location, for example: https://spacenews.com/china-launches-first-geosynchronous-orbit-radar-satellite/ though I imagine you have a lower orbit constellation in mind.

Not really. The various major military forces already have some sort real time tracking of surface naval units.

It is only during hostiles between major entities that interesting events will be play out.

Almost all civilian surveillance satellites have shutter control by their controlling authorities. Who will not hesitate to curtail viewing during contingencies.

SAR satellites in LEO are easy targets for direct ascent anti-satellite missiles. They even provide a guide path for the missiles to home in on.

Also jamming of the SAR satellites have to be consider during hostilities. Which will drastically degraded the capabilities of surveillance satellites with radar.

There is a huge difference with the operating environments between peace time and after hostilities have started. Reminder that the Russians bricked the Viasat satcom network during the start of their Ukrainian adventure.

There are restrictions on the specifics of what commercial providers can provide to third parties, but there are no remote-control-off-buttons on commercial satellites. The assumption has long been that any asset out in the open will have been observed by adversary satellites anyway (so don't leave things out in the open if you don't want them seen), and even degraded image restrictions are used very sparingly. You can go ask Planet for high resolution images of Groom Lake and get them, for example.

USS Eisenhower, probably getting ready to head home.
