And here's a clever twist on the story: J-15 fighters off the carrier Shandong, with smoke--and photographed from Landsat on November 26.

Forum member Deino is a rock solid source about chinese aerospace technology. Including their carriers.

One of the reasons that I kept this thread going is that I think that the factors that made the early story interesting--the leak of satellite photos of a Soviet aircraft carrier under construction in the 1980s--still remain valid today. Until a carrier actually goes to sea, one of the only sources of information on its construction is satellite imagery. Today that imagery is commercially available and prolific. So it allows us mere mortals to get information that previously was only available to a few governments.

Sentinel imagery shows USS Eisenhower 280 km off the closest Houthi-controlled area, which is beyond the range of most, but not all, of their missiles.

There has been lots of speculation about if/when/why the US may seek to attack the Houthis that have been targeting merchant and naval ships. But the politics of that are like a ball of spaghetti.

AIUI Djibouti is the only major port near the Bab el-Mandeb Strait and the Southern part of the Red Sea is within strike range of the Houthis (about 175 km). International naval vessels have to go much further afield to find another port for resupply of munitions, bunkerage and supplies plus personnel transfers. As in how long can International naval vessels sustain operations in the area if the Houthis degrades the port of Djibouti and make underway replenishment hazardous.

The Eisenhower and it's escorts and support ships are within range of drones at 280 km offshore. While it is likely that the warships can fend off drone strikes, not so much for the support ships.

Remember that the Houthis are in a medium level shooting war with the pan Arabic coalition for many years. There were some drone attacks on oil production facilities.

Sentinel 2 imagery shows the Eisenhower in around the same location.

China has now moved its new carrier (003) to drydock for further work.

To date, photos of China's third carrier, still under construction, have come from satellite photos, pictures taken out of the window of a commercial airliner, and a small number of ground-level photos (taken from a building or crane). It's mostly been satellite photos that have provided new information. Now Chinese television released a short bit of video showing the carrier being moved.

As time goes on, the commercial satellite photos provide less and less useful information. But they will probably provide the next indication that the ship is getting ready for sea trials.

Update: a nice graphic showing China's existing carrier, it's new-build carrier, and the USS Nimitz.

They are repainting the flight deck. It is half painted with orange primer right now.


Update: repainting continues.

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.

Not a carrier, but something very interesting--USS Seawolf with her bow off.

USS Connecticut I believe.  Seawolf Class.  Smoked into an undersea pinnacle at damaged the bow.

Will need to replaced the forward sonar array and everything else inside the bow dome along with the dome itself. Likely to be at that drydock until at least 2026. Complicating the maintenance schedule for the rest of the Fleet submarines.

If the boat didn't have a recent build nuclear reactor aboard, the USN might consider scrapping it and build a replacement. The submarine from what I understand might have sustain structural damage from impacting with a seamount that reduces its' service life.

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.

Looks like they are almost done with repainting the deck.



Update: a couple of photos from an airplane to provide a better look.
