It is possible that later 052Ds are retrofitted with CGT30 according to an official interview posted a few days ago

Wow. So this means the gas turbine output goes from 28MW -> 33.5MW, or an extra 5.5MW per shaft, or 11MW in total?

That should have a nice impact on top speed, as well as improved reliability and extra power generation for sensors and weapons.

When do you think this was first introduced? Or, how many ships already have this new turbine?

Do you think the Type 055 also got this upgrade for its second batch?

Though AFAIK they don't have IEP hence turbines are only for propulsion, I'm pretty sure they have separate turbo-generators. So it isn't as big of an upgrade as people think it is unless they also upgraded the generators.

Wait what's a CGT-28 again?

Basically, from this news report screenshot:



Though yes, we do have very little solid information available for the CGT-28 for the time being, and unlike the CGT-30, we aren't even sure whether the CGT-28 will be adapted for marine propulsion usage.

Anyways the main speculation on CGT-30 is due to the fact that it is advertised to be able to directly replace GT-25000 without modification to the mounting system etc.

Well, this development would be golden indeed.

However, considering that Baotou was commissioned back in the final days of 2021, yet the article posted by SOYO from several days before mentioned that the new GT work happened only two years ago (i.e. sometime in 2024), it does sound rather odd for them to just swap out the CGT-25s from inside the ship hull (which would necessitate opening the deck and associated structures) and install CGT-30s for such a young DDG.

But then, I suppose the ship designers have already considered such upgrades before or during the construction stages of the ship.
