      - Stern:      16.40 ft / 5.00 m
      - Average freeboard:   22.31 ft / 6.80 m
   Ship tends to be wet forward

Ship space, strength and comments:
   Space   - Hull below water (magazines/engines, low = better): 73.3 %
      - Above water (accommodation/working, high = better): 189.3 %
   Waterplane Area: 73,510 Square feet or 6,829 Square metres
   Displacement factor (Displacement / loading): 108 %

Would be the second biggest ship in Navalism. I'm fairly interested in the difference of design philsophy between the New Swiss and the DKB. On one end we have the Alaska design, about 10,000 tons less, and with 4 triples of a lesser caliber, like a soft kill design. On the other had we have this, heaver, bigger guns, and with 4 twins.

I like twins. Triples are OK, quads are the anti-Christ. Manly, I don't like the ABY layout, I like balanced fire. IF I use triples, there would be ABXY, so 12 guns and that's HEAVY. Now, I could go 4x3x15" but the it would weigh more, or 3223 ABXY and the weight drops, but so does the broadside weight.

The Swiss design is cheaper, faster, and would be finished earlier. It also uses 6 twins, not triples. Swiss philosophy is to soft kill the enemy before sinking them with torpedoes. Swiss battleships support the destroyers, not the other way around.

6 twin?!?!  :o. Why? Triples are much more efficiant, and you can get 12 guns with two less turrets.

The Rock Doctor

Six twins look cooler than four triples.

They do provide more redundancy,and may enjoy better rates of fire.

TexanCowboy

True, but since the Swiss seem to enjoy light-weight ships, and 4 triples are definatly lighter than 6 twins, you have to wonder. That is exactly why all my ships in the future will mount triples.

Guinness

I don't think the Swiss have a triple 14" turret.

Desertfox

Awesomeness > practicality... ;D The Swiss do have triple 14" turrets, but the ROF for the twin gunned ship will just own every other ship out there. Also triples are logical, can't have the Swiss be logical.

Finally, I can't have this ships unless it has twins:

and this Concludes your lesson on why the NS have never won a War... They get low on DDs by the end of the first year and from that point on they have insuficiant Naval power to do anything

(Nothing Personal DF but I watched what happend during the 2PW and saw what was left after it your Capital ships fared far better than your DDs)

Haven't lost a war either. In fact I have not lost a battle where my officers have fought as they where supposed to. And well, when have I fought where the odds where on my side? When you are outnumbered 4-5 to 1, doesn't matter how good your ships are.
