Logi's Design Studies

[Logi]

My take on Tan's fast battleship. In the effort of designing this ship to be 30 000 tons, I wasted about 2~3 000 tons on fuel just to meet the standard. I posted this design here, because I felt it would be rude to do so in his thread.

The engine specs are assuming the 1916 engines limit is 40 000 shp per shaft.

- Recoil effect (Restricted arc if above 1.00): 0.91

this is Bad (very very bad imho) that translates to literaly any damage and the ship is limited to end on fire.  While im not one to tell others what to build i would personaly consider widening her out a bit more, or perhaps lowering the freeboard a bit (I know it will play hell with your seakeaping).  Personaly id try to get nothing over a .75 at the highest

OH and 20K at 12kts is a little extream I would think (if you are at 60% fuel i bet she gets preaty livley though)

[Borys]

With the 13" gun, you could use the Italian 320mm as reference for older versions, and the French 330mm as reference for new.

[P3D]

I am repeating myself on the belt. Covers everything but protects nothing against high caliber guns. Freeboard is too high. You don't really need to be able to go round the globe on one tank either.

RRC plan on converting the coastal battleship, Shengzi, into a battlecarrier. The waterline was changed, bow and amidship lengthened, engines changed, and back half of the shiptorn out and replaced with a semi-flight deck. Purpose of this reconstruction is to test the pausibilty of a battlecarrier. If it indeed proves useful, the RRC may consider plans for carriers. If not... well...

[P3D]

No superfiring turrets (should have two). No end belt. Upper belt is superfluous if you don't have casemates. Main armament is underarmored compared to belt. Too high freeboard. Ship could be a bit more compact - reduce beam and length to save displacement. The ship is not fast enough that it'd need to be long.

[Logi]

I accidently forgot  to fill in the end belt, my bad. Lowered the thickness of the end and upper belts, increased thickness for main armament. Reduced freeboard.

4000 tons misc weight and 4000 tons of coal are representing the flight deck and structures to keep and maintain the aircraft.

I'd say the rules do not allow CVs built to mercantile standard - no way you could have all aviation equipment covered by a mere 2% of displacement.

[maddox]

Total weight spend on aviation is 12Ktons.  Displacement is 14Ktons light.

2%? 

Copy paste from the SS file below,

Miscellaneous weights: 6.000 tons, 26,6%

And that's doubled by the rules on misc weight vs fuel.

[P3D]

The new mercantile standard rule allows only up to 2% weight allocation for military stuff. Rule says

"A ship in government service may be built to mercantile standards if armament and armor take up no more than 2% of the ship's weight at normal displacement.  Such ships could include colliers, transports, survey ships, and others."

But shouldn't other military stuff included in it? Anyways, it should be discussed after the war, so as not to distract Rocky.

Rule 1

Play the game, not the rules.

[Korpen]

Rule 1

Play the game, not the rules.

That does not mean that one should ignore rules completely.
If we were talking about a merchant conversion with a fly-off and landing platform, one could argue merchant standard makes sense, but  not in a full-blown carrier. I think aircraft facilities are military, and should be included in the 2%, at least in purpose designed ships
