11"/45 are the only feasible option, the 12"/40s are too old for duty. The 11"/45 are on the other hand, modern guns. Don't get me start about how the 13"/35 have no range at all and have no turret to go with it. The only modern gun I above 11" is the 14"and it is too heavy.

The displacement was the result of the need for a long waterline length to achieve the max speed with the required stability ratings, though I can try without.

But the armor does allow it to stand up to any BC without backing down, even BBs. 13"  belt sloped 20 degrees is something to be feared.

But I think more than an effective commerce raider the design seems more inclined towards a fast battleship. Under-armed, but able to try down large forces nevertheless. Faster BCs have more speed, but not the armament or armor to compete. Having a large armament is useless against BB-style armor.

Slower BBs can not hope to catch up with the ship.

All the following designs employ a 20 degrees sloped belt.


If I went for an increase in tonnage and gave it the 14" twins (that I just remembered I had!).

4 guns is pointless, you need at least 6, and that's BARELY enough, for Fire Control spotting.

The 24cm one has promise, but why slow it down? 29kts won't outrun the last 2 classes of Dutch (who are now cozy w/ MK and have bases close enough to you to worry about) Frigates, will barely (0.50kts) outrun the new French (who are friendly with Indochina, who you want to immolate) Croiseurs de bataille, will barely outrun (1kts) the DKB (who, despite the Dutch trying to weasel us out, are still friendly with the MK and Indochina) 11" armed Motke's (yes, we know..treaty and all, but one must prepare for the worst and hope for the best), won't outrun the (4+yrs older by completion) Swiss (10") Interceptors and barely (1kt) outruns the Swiss (14") Inflexible's. If you're going to down gun that far (20-25cm) you better speed up.

[Logi]

I was going for the 24cm because I thought I had it (my internet was down when I made the design) but I realized by checking I only have a 250mm and it's a L35. I guess we know what gun I'm developing next.

Probably going to revert back to the 11"/45 or downgun to the 195mm/50.

[Sachmle]

19.5/L50 isn't a bad weapon....for killing other cruisers. It's certainly not anything for a capital ship to be afraid of. However, presuming you have triple turrets (since RRC seems to like triples) a pretty tough customer for other cruisers can be had w/ 4x3x19.5. Just remember what I said about speed, cuz it will apply even more so w/ a smaller gun. DKB has been toying w/ various ships bigger than kleine (small) kreuzers, but smaller than große (large) kreuzers (i.e. Battlecruisers) and have not decided what, if any route it will take. We have designs w/ 19.4cm/L50, 21cm/L45, and 24cm/L45. The 19.4 lacks punch, the 24 weighs a lot, the 21cm seems a nice compromise, perhaps you should try something in that size range.

[Logi]

The RRC actually likes Quads, but the jump from 8-12 due to quads is hard to swallow.

Hmm I was thinking of going 21cm/55 Quad route. Nice firepower, range. Just nicely between the older 195mm/45 and the 240mm/35.

Here's a 21cm/55 Quad Version.

8" belt is pointless w/ a 1.5" deck. If you're fighting something the has big enough guns that you need an 8" belt, it will cripple you by punching through your 1.5" deck long before you close to damaging range w/ you 21cm. An 8" belt will stop 12-13" at long range, 10-11" at medium range, and 9" or smaller at most ranges. However a 1.5" deck will be defeated by 14" at 8,000yds, 13.5" at 9,000yds, 12" at 12,000yds, 11" at 13,000yds, 10" at 14,500yds, 9" at 16,000yds, and finally outside FC range, 8" at 19,600yds

[Logi]

Using P3D's ballistic program, I get penetration by the 21cm @ ~16,000 yds out. For the belt, penetration by the 21cm @ ~11,000 yds in.

Upgrading the deck to a 2.2" deck, with get penetration by the 21cm @ ~18,200 yds out. That is outside of FC range. However, upgrading the belt will get penetration by the 21cm @ ~9,600 yds in.

My solution is to increase the thickness of both belt and deck by 1". That extends the immunity zone against it's own guns to 8,600 yards (as opposed to the previous 5,000 yards).

Against normal weight 21cm shells, the ship now protects against @ ~9,000 yds out (belt) and @ ~21,500 yds in (deck). Thus the immunity zone against normal weight 21cm shells is 12,500 yards.

Using NAaB w/ the following settings
Vertical Armor: 8" German new KC 'n/A' (New Type) @ 20* w/ 12" wood and 2" High Tensile Steel WWI backing
Deck Armor: 2.2" German Krupp "High-% Nickel-steel (1894-1918)
Projectile: 8.2" 335lbs Total weight, 333lbs body weight Avg. L/3.2, L/3.4 APC (0.50-cal-KCa/A@30-deg, TNT, and delay-fuzed) (1911-1918)
2400 muzzle velocity
8 ballistic coefficient

An 8" Belt of KC n/A at 20* is impervious to a "SuperHeavy" 8.2"/L55 shell from just inside 5,000yds and out.

A 2.2" Krupp High % Nickel steel deck is impervious to a "SuperHeavy" 8.2"/L55 shell from 19,250yds and in.

Basically, you can cut you belt. IF you want an immumity zone against your own gun of ~8,500yds and closer you only need a ~6" belt.

However my original point was not that she couldn't stop her own guns, it's that she would be crashed by any number of EXPECTABLE enemies at RANGE due to her thin deck. I'd cut the belt/turret face/barbette to 6", the turret other to 3" and put the extra weight into the deck. At 2.2" she's still vulnerable to  anything over 11" at FC allowable ranges. Last I checked 11" was the smallest heavy gun used by your probable enemies. Remember, no one fights fair. They're not going to send their 8" gunned CA to stop you, they'll send their 13-15" gunned BC to stop you, and at 18,000t you're in the bracket where it's not really that cost effective anymore either.

Interesting, decreasing the armor for the turrets yields this:

A 9" Belt of KC n/A at 20* is impervious to a "SuperHeavy" 8.2"/L55 shell. It seems at any feasible combat distance.

That's a lot of armor for a cruiser...I like it.  But then I liked trying to build Armored Cruisers outside Washington Treaty like restrictions in WesWorld (Battlecruiser equivalent armored cruisers with 8-10" guns and high speeds)...Or basically what Rohan would do for a Combat Cruiser.
