Any comments ?

Germany would recommend against the 88mm as a primary or secondary armament. Great War experience says that the 88mm, while a useful AA weapon, is too light for use against destroyers, it simply doesn't hit hard enough to effect target.

Really ? Do you mean it would be better to change the 88's against 105's or even the 125's ?

Yes. Germany would definitely recommend the 105mm over the 88mm for naval use. The 125mm would be even better for anti-surface use, though it may or may not be superior for AA service.

the Xia - Class:
replace the 88's with 105's


the M - Class:
replace the 150's with 203's or with 230's
replace the 88's with 105's
=> it's a great redesign, so this modifications should be done if the Class is completely redisigned
=> the replacement is done in the Advanced M - Class


the Hong-Ming - Class:
no changes, because the 125's is good enough against destroyers and the 88's is only against light vessels and for AA use

**********************************
will present the redesigns as soon as possible
**********************************

what exactly is the point of 18mm belt armor and 10mm deck armor?

And 5,500 tons is a lot to pay just to get 6 125mm guns going 32 knots. I mean, there's DDs that do that just as well.

I still don´t understand why a small navy such as the Chinese needs or can affort three different CL classes of very similar size. Doesn´t look like a clever plan to me....

Regarding the designs - you seem to prefer long, slender hulls with low BCs. It is my opinion the M-class could be improved using a more common hull form.

Ok, thats outside of Dutch expectations.
As for German advice regarding more effective guns, Grr...

I don't see much merit in an AA cruiser of any kind unless/until China has a capital ship that requires the protection.

Since you don't have much trade protection or capital ship escorting to be done, I'd recommend China concentrate on fast, powerful striking cruisers - a slightly larger M class, with better protection, would be quite the pain in the arse for your enemies.

Actually they do. They inherit the former Formosan carrier and battlecruiser. Also they are planning building a carrier designed by the Australians.

Ah, yes. Forgot about that.

Hopefully the Aussie design doesn't include a remote-controlled scuttling charge.

I will refrain from commenting on that. Everything I say, can and will be used against me!

Germany doesn't necessarily recommend replacement of the 150mms on the M-class design. That would result in a rather different ship, and that's not the intent of the recommendation. Germany would simply recommend replacing the 88mms on the M-class with 105mms, because the 88mms are too small to have much effect on hostile destroyers. The 150mm weapons are fine as is, no need to change them.

The ships of the Xia-Class should protect the Chinese BC and the carriers.

Interesting designs. I´d never build them that way but would all players build identical ships - where´s the fun?

Still I´d like to comment on two things.

In OTL the Dutch build a sister to CL TROMP which wasn´t completed when the Germans came along. So the Dutch Navy send this unit to the British to have her completed. Well, actually the latter turned the ship into a small AA cruiser with 10x4" guns and some Hazemeyer 4cm AAs etc. In fact, they build a ship very similar to your re-designed XIA on 2/3 that displacement. So if I had to decide which design I´d take the Jacob van Heemskerck would always win hands down.

Your new M-class features 10 8" guns on less than 10kts. Combined with a weird mix of 10,5cm and 88mm guns I´d says that´s overkill. While armed to take on the heaviest CAs in WesWorld she lacks the armour to stand up even to light cruisers and the speed to get out of harms way should she really be seriously encountered.

Of course there is one good thing: Both designs will be good for interesting stories if you plan to have them involved in something in the near future. And they both proof the Chinese shipbuilding industry in not yet up to the standards set by the big players - which probably is the most reasonable that can be said about both designs, IMHO.

That is more or less exactly what I intend with the designs.

Britain, France, Germany, or the all the other great seafaring nations would certainly NEVER build these ships, because they have enough experience, how the vessels for the tasks have to look like. But the chinese ship builders didn't have these experiences. China must first of all make these experiences themselve, and I think these designs are wonderfully suited for that, right?

Maybe chinese ship builder will shake their heads in a few year if the look back, but at present these designs are in their eyes okay.

I'd be a bit worried whether the M class has enough beam to mount triple 8" turrets. Also, the contrast in armor between the smaller Xia and the M is rather marked, and ought to be noticed.

Is there a minimum beam for mounting triple 8" turrets ? I don't know ?!?!?!

Uuuuuppppssss is there a fault ??? Yes . Will be corrected.

(only 8" twins and thicker armor)

I would definitely trade some of that deck armor for more belt/turret armor: right now the belts and turrets are pretty lightly armored for a ship with 8" main guns, while the deck is rivaling that of ships more than twice as large.

Also, there's still an error:

Quoted

Main guns limited to end-on fire
- Recoil effect (Restricted arc if above 1.00): 1,13

Ie, you've got too many guns with too much recoil on too small a hull. Widening the hull would help some.

Try looking at some of the RN's CA designs for suitable ships in the range you are trying for.

Other than that, China might be better off asking Japan to design them an updated Yokino class CA.
