It's a fast battleship -I stole the bow turret idea from the RN's Lord Nelson class.Thanas wrote:You still have the same end-on fire problem as I do. Ergo, no broadsides for you either.
Post the report you got?Thanas wrote:Hmm. Methinks that Springsharp is a bit bugged in that regard as even the Iowa has that limitation when I know that it did not in real life.
Perhaps its making some assumption about the recoil-absorbing mechanisms that are incorrect when it comes to the Iowa?Thanas wrote:Hmm. Methinks that Springsharp is a bit bugged in that regard as even the Iowa has that limitation when I know that it did not in real life.
Maybe at lower values, but IIRC even historic ships were below that composite strength. I shall have to ask some naval experts I know for clarification.Thanas wrote:It will however results in a cracking hull, thereby making the ship far less worth. At least that is my understanding of it.
Maybe, but usually if COmposite strength is 1.00 then it won't give a warning, from what I see.Fingolfin_Noldor wrote:I think it's not composite strength that is throwing out the warning, it's cross-sectional strength.

I'd remove the 8'' - not good enough against battleships, but too slow-firing against destroyers closing in. Placing them in casemates is a bad idea, as they might not be usable due to seaway. Increase the size of your 4'' guns to 5-6'' to have a good secondary battery, and keep a few 4'' as heavy anti-air battery. The 2'' guns will not be helpful either, I'd remove those too.Norade wrote:With a normal weight of 50kt this is the pride of the Portuguese navy and is expected to be finishing sea trials and receive her commission no later than March of 1925. That is assuming she isn't scrapped on the drawing board.
Any comments, I'm trying to design a heavy ship that can swing with others of her weight class while running down smaller ships.

Because turbo-electric drive has in fact been used on capital ships. The US Navy used it on the Tennessee and Colorado class battleships, as well as the Lexington-class battlecruisers/carriers. The unbuilt South Dakota class battleships also used it, so it seems likely the USN would have continued using the setup had it not been for the WNT. The disadvantage of the system is that it weighs somewhat more than a conventional turbine setup, (which is probably why it was not used on the later treaty battleships), but the advantage is the machinery arrangement is more compact and flexible, allowing better underwater compartmentation, and more hull volume to be devoted to the torpedo defense system. Other advantages include the ability to switch the propellers from forward to reverse far more rapidly, and to run them in reverse at maximum power. Unfortunately, Springsharp doesn't actually sim the weight/volume differences; not yet anyway.Thanas wrote:I'm not sure why you have steam turbines and electric motors listed.
