055 Large Destroyer Thread II

[antiterror13]

Is there any confirmation that the 2nd batch of Type 055 (i.e 055A) have Integrated Electric Propulsion (IEP) MVDC and 4x CGT-40 Gas Turbine ?

To me it is a massive upgrade. It seems China has 3 other ships with Integrated Electric Propulsion (IEP) MVDC 054B, Type 076 and Type 003

No, there are barely any known changes to the new batch, 003 and 054B are also not IEP. 076 is the only surface PLAN vessel to feature IEP.

Someone remind me of status of hulls 15 & 16?

Doing such massive changes to the 055's propulsion and onboard electrical power system (swapping CGT-25M to CGT-40M, converting COGAG to MVDC IEPS, etc) inside the hull would require the degree of changes to the exterior visible superstructures that would've become apparent to any normie observers long ago.

And given what we've observed on the 9th and 10th 055 DDGs (which basically have little to no changes) - The answer is a resolute No.

Also, as mentioned by @Tomboy - As of present, only the 076 LHD (and the 2000-ton integrated test platform USV) has IEPS.

They could at best have CGT-30 because it fits the same space as CGT-25. This would be a huge upgrade already.

you meant QC-280? CGT-30 is for industrial (not marine)

CGT-30 is marine as well and its called M variant.. there are rumors of CGT-30M GTs on the newer 052D DDG..

looks like you totally missed this news. see this information down below.

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.



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.

Some more information on the switch to CGT-30M GTs on the newer 052D DDGs, by SOYO on Weibo.
