Orange Capital Ships - Old Thread

[swamphen]

The battlecruisers being built would be a shameless copy of the Brandyburger SKs

Call my laywer!!   :P  ;D

Building ACs is a good idea, if AC means a fast cruiser with 8-9" guns to kill PCs and run away from BCs

Ergo GK1909 (which I should try to squeeze another knot out of. Hmm by then I might be able to use AllOilFiring...and they're kind of a "Versuchs-Kreuzer" anyway...)

[Desertfox]

Stop copying my ideas (ie AC)! Now where did I leave my lawyers?

Some refinement on the ship - an extra 400t allows lengthening the belt, and placing a few torpedo tubes into the hull.

Redesign of the 6x14" BC. I have to use those turrets I paid for. Range decreased from ~7000 to 6000@12kts, added displacement, some finetuning for better armor, deeper draft and there it is.

[The Rock Doctor]

She's starting to look over-armored for a battlecruiser.  The block-coefficient is on the low side for a capital ship, even a fast one.

She's starting to look over-armored for a battlecruiser.  The block-coefficient is on the low side for a capital ship, even a fast one.

This is not a battlecruiser any more, range was reduced.
BC is yes, low, but it is like with the HMS Nelson  (BC ~0.50). The hull was lengthened in order to keep the powerplant - and thus the machinery spaces need to be heavily armored - small.

Orange Fast BB laid down 1907 (Engine 1909)

Still think she is over-armoured and undergunned for ship that size, but to each their own i guess.

[Earl822]

Right, far too much armour for her speed, loose at least 1 inch from the main belt. 6inchers won't be QF for long as they'll soon run out of ready ammo, reducing the rpm right back down. She is too big for a BC at the moment, and if your planning on tackling the Kaiser Wilhelm II class you'll want more main guns as with ranges closing the German ships greater number of main guns will tell heavily. In fact she can't absorb as much damage as her German Opponent.

[P3D]

Orange has a few 13.5" turrets from France. My option is to build either two of the 6-gunned fast BBs - having the same speed as my BCs. Or build one ship with 5T3x13.5" with 23kts, and a displacement of 27000t, and then my two other 6x12"BC would have 1kts that they cannot utilize if in the battleline. Something will be built, for political reasons.

My ships are overarmored to historical designs, but we are speaking of 5-7ky fighting distance, not the 10ky+ the Dreadnought was designed for, and they are battleships not battlecruisers. Not everyone has fire control. For the high speed, blame the escalation on the DKB, which decided to take Orange as enemy #1 - and I do not really have other big concern. I can neglect building cruisers, as I do not rely on overseas commerce. The DKB cannot.
14" armor will stop 12" uncapped projectiles at 7ky. Not 13.5" ones.

Undergunned - a twin 13.5" is roughly the equivalent of a triple 12" in weight. And it would be 6 gun vs. 8 gun the most time, not too big advantage to the Germans, with my broadside being heavier, and able to punch through his armor, but not vice-versa.

Better flotation for the KWIIs: 1 knot speed makes 4000lbs difference there.

As we are talking mostly un-capped AP shells, scatter is much more likley.
And i still say they are undergunned for a ship that size, i have a 21kts design with 10 35cm guns on 20k ton without giving up too much armour...

[The Rock Doctor]

Given that the seas around the Cape can be rough, have you considered reducing the armor (the deck perhaps) a bit and raising the overall freeboard a bit?  I know the seakeeping value is fine, but I wonder she'd be wet aft, and whether it would impair gunnery from the turrets there.

Unfortunatly true. :(

I do not have the luxury to build slow, 21kts ships  unlike most players.
My primary requirement is 24kts speed so Swamphen's twins could not escape (0.2kts difference is negligible). With 1909 engines if I have 8x13.5" guns, it would be vulnerable to 12" or even 10-11" guns, and I won't get much more firepower so  that's not an option.

True, I might go back to the first BC design which did have 1.50 seakeeping and higher freeboards aft. But the 13"/4m stern freeboard is pretty much what the first German BCs had, and they were supposedly designed for the North Sea.

[P3D]

Heeding Rocky's suggestion, I decreased deck armor thickness, and belt depth, and incresed freeboard by 1'. Range was increased.
