Possible AC for NUS

[Sachmle]

I took the stats on the RN Lion class BCs and toned it down to fit a type 2 slip and swapped out the 12" for 9.2"s as she's not a BC, but an AC.

[Borys]

Good!
I'd say overarmoured, but small navies have to go for quality.

Borys

How thick would you recommend for the armour? 5" belt? Or do you mean the turrets and barbettes?

Yes - I think a 4-5" main belt and 6-7" turret faces should suffice.

And I think two funnels will be enough.
Borys

[P3D]

Pretty extensive armor compared to my Furies, although bit thinner. Overall, pretty much comparable - and overarmored if you want her to face only 6" gunned CLs - that's why I have a design on 2-3000t less with reduced armor.

As a note, a Fury would disengage from ships of similar strength on a commerce raiding/protection mission until reinforcements arrive - most of the time.

[Borys]

I like this version better.
Like P3D noted - the job of such ships is to chase down/chase away the 6" armed cruisers.

Now, thinking of it, in N-verse the heavier armed version cost less than 1$ and BP more.
For a small fleet like yours maybe a heavier-armoured ship would be better.

The KK would had tried to build a 10,000 tonner with like armament.

[Sachmle]

I tried. Would cost me too much speed, or a MB turret.

[Jefgte]

Very good AC with a strong hull.

Just a question:
Do you think that 4" guns are enough to repulse 1916 DDs ?



Jef  ;)

[Sachmle]

Maybe, maybe not, but 6s are too heavy to fire fast enough to hit 1916 DDs often enough, and I don't have a 5"/127mm.

[Jefgte]

Iberia & Peru use 120mm guns.



(I use 120mm for secondary armament on my old EC &  new AC)



Jef  ;)

[Sachmle]

Yes..could trade, but would take year to make "Own" versions..

[P3D]

Do you think that 4" guns are enough to repulse 1916 DDs ?

A few 4" hit in the machinery spaces would slow down the DD just as fine. The main advantage of larger shells is the longer  range IMO.

With a broadside of 5x4" and 8 9.2" guns capable of taking out a DD from distance I won't be much worried about a 28kts ship vs destroyers.

[Sachmle]

And since it's 6x4 and 8x9.2 I'm even less worried.  ;)
