A. Torpedo Bulkhead, unneeded. Waste of tonnage.

B. Rather thin belt and deck for this size ship.

On the SS, no. But in reality, that would be a waste of tonnage, as adaquate beam for the TDS to work is not available. I, personnally, consider 80 feet to be the minimum.

If the Nverse Dutch decided to build a treaty cruiser, I think it would be faster. As it is now 31 knots would mean that this ship couldn't even run from the CSA's fast new armored cruisers (for instance) or many of their contemporaries. And with this armament and armor, this ship certainly couldn't fight one of those. In fact, I suspect it would have trouble with two 6" armed cruisers.

You'll find many here are hostile to the treaty cruiser as a concept, and for good reason. The 10,000 ton/8" Washington limit in many ways imposed uncomfortable limitations on the signees.

Personally, I think the Dutch would benefit greatly from a more "conventional" 150mm armed cruiser, of say 7000ish tons and 31.5 knots or so, but that's just idle speculation on my part.

Some things.

1. I have three years of infrastructure to catch up on.
2. I don't have a gun calibre family that makes sense. Its either too heavy or too light per class band.
3. 7000 tons is 7BP and 7$. I only have 19 per half year to play with. I therefore need to budget to build the cruisers for a fleet that had destroyers that we tacitly agreed now would not have 8 or 10 120mm guns and pass themselves off as light cruisers. We retconned that to make sense.  
4. Speed speed speed; in the real naval world it didn't matter. One knot or two knots, once you hit the engagement range bands you were getting medium calibre ladders and hits every thirty seconds. or less......

See here.....

55 k/h ~ 30 knots ~ 15.3 m/s  459 meters in 30 seconds
60 k/h ~ 33 knots ~ 16.5 m/s  485 meters in 30 seconds

<0.00946% bearing correction in gun lay at 10,000 meters to cover the 26 meter difference?

Is it any wonder that I don't see top speed as critical? Its the ability to dodge.  


   


 

TexanCowboy

And once those extra three knot's start adding up....and dodging will take you farther off of your course, slowing you down even more.

Gun caliber: 250 mm, 6 of those, would be my preference.

maddox

Pity about the length, now you'll need those rare type 3 docks and slips even more.

damocles

Respectfully disagree. The chase the splash solution does not change the essential gunnery problem here which is that you confuse baseline track stern chase with each bearing range solution which is an independent event and not calculable as anything but an independent event.

Also who assumes that if you chase that you are being wise here? There is such a thing as sailing into a Kaufman or Arleigh Burke ambush.
==============================================
Four shell ladder is the minimum size for optical fire control. I have some 4000 tonners designed with 6 x 150mm but then those are pack fighters not intended to operate as lone wolves so 1 and 1/2 ladders is acceptable.

Something this big though may have to engage two 4000-7000 ton targets.

You have some weight left you can use (1.05 composite). I'd try for a little more speed, I think you may get 1kt out of it, but it will drop your seakeeping more to do so so you may have to go to 10,000t light so you can add some freeboard to make up for the extra speed. 28kts isn't 'slow' per se, but there are things that go 30+ knots that would eat this for lunch and want a second helping. I understand your philosophy on strategic vs tactical speed, but being unable to run from a superior enemy is a bad thing. This is why top speed is somewhat important.

1. Most of them are bigger and shorter ranged than this ship.
2. Money and time.
3. 1 knot over 28 knots over a 5 minute gun duel  adds 1542 meters or 7/8th a nautical mile I can cover at 29 knots as opposed to 28 knots. It isn't worth it.  Two knots and I bust the 10,000 ton limit. (See 2)
