Offered to Orange. Being that Erwhon's capital ships are built abroad, it's not too surprising that our first export design isn't up to par with the other entries.

Serious Battlecruiser you have here elft177.

Walter, quite a lot of 2nd and 3rd armament, don't you think? Not that it's bad it just catch my eye.

I'm not going to comment on all suggestions btw, but they are all considered.


The French anti-Orange design made me think. In the end I decided to try out how much firepower and protection I could stuff into a size 2 hull at the expense of speed and range. It's nothing serious, just a design study, but here take a look:

Well armored, well armed.

But, stability is low, for battleships we aim for 1.10, with some leeway.  seakeeping is good, maybe you can lower the freeboard a bit, gaining some stability and weight for secundaries. (also, you asked for 6 to 7" secundaries, but this design uses 5")

Also, a suggestion, get a few of the secundaries  superfiring, will improve firearcs a lot.

[Walter]

Walter, quite a lot of 2nd and 3rd armament, don't you think? Not that it's bad it just catch my eye.

2nd and 3rd? Quite a lot? Actually I don't think 2x2x2 is a lot of guns so that's where the smaller 4th armament comes in. :)

Anything above 1.05 I consider good enough (though the more the better). Adjusting trim to gain stability is also an option since lowering freeboard would most likely result in the loss of the "good seaboat" rating. The secondaries asked for were 6" or 5" and I agree with having some of them superfiring.

[maddox]

By lowering the freeboard with on avarage with 20-30 cm it's perfectly possible to retain the good seakeeping, and gain some stability too
, as well more weight for armor, and less hull to protect.

It's all a balancing act, but the seakeeping is important for the OR, as these ships sail the worst waters on earth, the roaring 40's.

By lowering the freeboard with on avarage with 20-30 cm it's perfectly possible to retain the good seakeeping, and gain some stability too
, as well more weight for armor, and less hull to protect.

I'd have to check it with SS, but I doubt that seaboat quality will remain above 1.20 with a 20cm drop and I seriously doubt it will it get stability to the level you are thinking of. :)

[maddox]

It's a way to get the last bits out of a hull, never said it was holy.

[Walter]

Just tried it out by lowering the freeboard by 20 cm.
Stability... 1.02
Seaboat quality... 1.20... rounded up (so no longer good seaboat rating).
Gained... 0.01 hull strength.

I still say that adjusting trim is better. :)

[maddox]

Walter, your way is costing gun platform steadyness.    :)

[Walter]

Getting better stability on this ship has a price. And besides, I only think gun platform steadiness is worth it if you can get it to 70% or beyond (naturally without compromising the ship's stability).

[Nobody]

Played with your suggestions a bit, but I suppose the ship is just too small to hold 3 quads. The only reason for the good seeboat rating was the ridiculous low speed anyway.

I wondered how you managed to make the ship that small Desertfox, but without torpedo bulkhead and only 3 inches of deck its not that surprising.

Walter I obviously meant all 6" guns are 2nd and all 5" guns are 3rd battery ^^


Now lets take a look at this. Any suggestions how to increase seakeeping? I think the freeboard is already pretty high (same as Bismarck's). You think bow and citadel splinter protection will do me any good?
