Bad choice of name. Obviously the marketing team do not understand whale shark's behaviour.

Why not just call it as it is, type 052E, "E" for export.

Whale sharks are slow and fall prey to several creatures. They don’t even attack back since they are filter-feeders. The whale shark is often prey to a variety of fish that includes sharks, blue marlins, killer whales, and humans.
Humans are fish!

If Type-052E (or whale shark) happens, it will be similar to US Burke's destroyers Asian versions that Japan and SK uses.

A major signal that whoever orders these vessels, they are becoming an important ally of China. My money is on the Saudi's for many reasons that I don't want to start discussing. They probably ordered 4.

Sorry, can we discuss the likely max speed of the 052D? I am aware that the most common open source estimate is 30kn and US sources frequently cite this as well. Then again, the stats stated for the export version state max 28kn; however all stats given seem to be all over the place. Such as length in between the batch 2 and 3 estimates and the stated tonnage lower than all estimates etc.

Based on what I could piece together from searching the forum, the 2x UGT25000 (?) gas turbines appear to be similar to the LM2500+ (based on a Chinese paper posted in the propulsion thread), so approximately ~30MW of power with slightly lower efficiency of around ~36%.

With ~7650 tonnes gross for the lengthened ships and a rather narrowly shaped, streamlined hull, around 30kn should be possible or not?

If we estimate with 159x17x6 (Lwl,B,T) and Cb 0.45-0.5, then something with 80-92k shp should atleast be able to hit 32.5-35 ±2 kn. I would expect closer to 50-60k shp for something that only reaches 28kn.

Even without estimates if we look at some old ships like the WW2 Atlanta-class cruisers, those had close to 56 MW of power at ~7,400t and hit 32.5-33.5kn in service. That's pretty close in terms of tonnage and power to the 052Ds. 28kn would imply propulsive efficiency decreased significantly rather than increased in the intervening years which is basically impossible.

To put it another way, at 80k shp (60 MW), I would expect even a vessel-shaped like a brick to hit at least 27kn.

The French Aquitaine class is 6000 tons displacement and has 32 MW (CODLOG) propulsion power at high speed. Its top speed is 27.5 knots.

The Horizon class frigates are 7,050mt displacement and have 46,6MW turbine power (CODOG) for high speed dashes. Their top speed is 29 knots.

I think the vanilla 052D is in the vicinity of 7,700 mt. The stretched version should be around 8,000 mt. Given that they have essentially the same propulsion as the Type 052B, I find the 28kt top speed plausible.
