Too wide beam and shallow draft - B:D is 4:1, it should be around 3:1 to save a few tons.

In an effort to narrow and deepen the ship w/o dropping the BC to a ridiculously low number I had to INCREASE weight, but I used it for more speed and a longer/deeper belt and thicker CT armor.

On a 170m hull you have enough place to install directly 12TT & no reload.
The advantage is that all TT are directly operational - no reload time -

Excellent design slightly larger guns, same torps and mine layout as the Italia Taranto class but with more modern engines and about a 1000 less tons and only 1 knot slower.

Ammo - 154 per gun (last), 1848 total vs 2000 vs 1600 - so 2nd.

Mines - 0 - 3rd
Stability - 1.22 - 1st
Stability - 70 - wash
Seakeeping - 1.04 - 3rd
Survivability shell - 3,973 - 1st
Survivability Torp - 0.8 - 3rd

Total  (inc ties)
Liepzig - 6
KK1921b - 8
Taranto - 6

So..Leipzig is only 5,000 tons, with coal firing 1912 engines and antiquated main guns layout. The coal firing actually makes her a better merchant raider because she can refuel from any prizes.  Despite "6" points, I really don't think she's in the same league. Although both KK1921b and Taranto have speed advantages, both would have difficulty finding a range where they could penetrate Leipzig's armor without getting holed in return- though Leipzig's casements limits her current longer ranges until the 0.8 shells come into use.   Overall I'm not sure this is a good method of comparison.

On the other hand, against DDs she's may be more effective at tracking than the Kk1921b, considering it's twin 150mm gun houses have a rotating weight of 47t which is close to that of the gun mount criticized on the Omahas which came in at 51.8t  The Taranto's 42 ton mounts are light in comparison.

(note- Liepzig is only 120m, so for belts this is 141% vs 110%and 119% coverage, 1st by that measure, would be 7/8/5)

Like I said an Excellent design so is the Leipzig class given her technical limitations and as a raider she has a real advantage.

The Taranto class has a clear advantage over the KK1921B in that there are currently two in service and 4 more under construction that will soon finish.   Heck one was lost in the recent fighting with New Zion and New Swiss.

I really like all the Designs and if I could have gotten 31 or 32 knots for the 1000 tons less weight I would have but I think thats because you will be using the 1917 Engine Tech instead of the older tech I had to use.  Italia just got the 1917 Engine tech so any new Cruisers will be using it.

Hey Dont Forget that I can also sacrafice some sea keeping if my ship is going to be primarily used in the Mediteranian Ocean.  Given that My Ships can stay in the Med or Rift seas and never be more then 2000 NM from a Port  I could even sacrafice range.

My own comparison to my own design. I did not include yours snip as you posted the design whilst I was formatting.

I did not include throw weight else the U1922A would have placed 2nd behind the Leipzig and 1st if we only counted the guns that could be brought to bear on one side.

He says it's so they can run at high speed longer and/or stay on station longer w/o refueling. I'd also through in that they could refuel destroyers off the CL if it was operating as a leader.

Yes, that is true. Keeping up speed can be important. Other reasons as well. This one is a raider, hence the very high range. (also helped with seakeeping, but I could always fiddle with freeboard) For the BBs, well the MK is done being a coastal only force. There are bigger fish to fry that require moving away from the shore. but thets not completely jack the thread.

I like the design, its a good little CL
