Those events didn't transpire in my AU. There is no Great Britain, no Japan or United States in my AU. You are asking the people from my timeline to predict the future and see events from an alternate reality and then design their ships to be perfect.

Again, if you invoke real solutions, you must face the real consequences. Those solutions have reasons. A lot of those reasons are called PHYSICS.

One correction. The steam catapult was trialed on the HMS Perseus, not HMS Theseus.

Does anyone understand what he is talking about?

Unfortunately Krases, Tobius has forgotten that for most of us we are here to have fun drawing our ideas. We do not care about PHYSICS, as most of the PHYSICS Tobius bangs on about were not always known by the designers of the early 20th century. A lot of shipbuilding of that time period was by trial and error. The errors lead to more understanding of PHYSICS. You almost have to be rude to Tobius before he will leave your thread alone and let you get on with what you want to do.

The two by triple turreted 16" battleships came about by the AU I was working with designing and building (two) 12x16" battleships of a size of the US South Dakota Class (1920's). I let the Washington treaty cancel them but put the 8 triple 16" turrets into storage for use later. The first four triple 16" are used aboard two 'pocket battleship' killers with a fore and aft armament. The second pair of ships are the ones above.

It should not be difficult to make the ship a bit faster if required and make space for your helicopter deck. I am quite happy to help if you want to PM me with questions.

Wanted to do a Destroyer Leader with a layout like the British Nelson class BB. Has 6x5" dual purpose guns.

This is an escort destroyer I wanted to make, instead of three 3" guns, it has a single twin 5" DP turret stuffed into the front...both these ships may be a bit front heavy.

And a super battleship because whatever. Mostly an excuse to try and layout those 60mm, 30mm and 15mm secondaries.

Don't bother with 15mm AA, after about 1940 it is found by countries that the shells lack the size and knockdown power. 30mm would be the minimum to carry. Most countries that had the time to be able to do some research were looking at 40mm+ to 100mm fully automatic weaponry (though these weapons did not enter service till just after wars end 1946+).

If you do not already have this page bookmarked, it is probably the most useful on the web for us amateur designers:

With the DD's you will need to move the guns back from the bow a bit more to balance the weight issues.

I dont really want to make perfect weapons so much as I want believable ones. Like the 60mm is like an american 3" AA gun and a 40mm, but with a lower mean rate of fire between the two. Really heavily looked at the Molins gun for inspiration. Heres the only video I could find of it firing.

https://www.youtube.com/watch?v=_xVvaQNlq54

The 30mm I looked at a lot of German weapons, but there is also the American 28mm gun I like. Mine is like that, but slightly larger and without the teething problems (or the teething problems were worked out) http://www.navweaps.com/Weapons/WNUS_1-1-75_mk1.htm

The 15mm I sort of imagine as being a bit outdated, its fast fire rate being much loved in my worlds 1930's, but by the end of the war it was only liked for its reliability, despite not actually being very useful. The war would be practically over by the time it was truly proven to be not useful.

This is a 2x3x16" 35,000 ton BB I did for one of my AU's. I would be happy for you to use it as a start point for the BB you are looking to produce. Remove the aft centreline 5.1/130mm DP guns and leave the broadside turrets. Give you plenty of space aft for your heli deck. It is a 30 knot ship on 140,000shp. The AA are twin and quad 40mm.

Ive started to use your drawing, I will post something when I have created work that is more substantial. I knew in theory I was able to do this, but didn't sit down and actually try to do it. I moved over from 300 ppi to 72 ppi, set stroke width to .25ppi and now when I rasterize it typically comes out to the one pixel thickness standard in shipbucket. I feel like I did this before but then forgot I did it. ><

So yeah, getting adobe illustrators CAD like features to work for making shipbucket drawings would be really handy.

Yeah nevermind, that ended up being more of a pain than just using photoshop to build things.

Anyways, I am trying to build a "super Fuso" because I always liked the Fuso's look. Problem is, how am I going to cram a ton of AA in there? Ive actually been thinking about that more and more, how can I really jam more AA into a battleship and what sort of layout really aids that design choice. Probably less turrets is better.

No battleship was ever exclusively built as an 'AA' ship. All were designed and laid down as battleships to fight other battleships. That when they were completed their roles had changed to being AA support ships for the carriers is just how short a time that it took the Aircraft Carrier to replace the battleship as Queen of the Seas.

So any Battleship you design is going to be armed to fight other Battleships first. Aircraft a long way second. So don't go overboard with AA on your designs too early. You also have to remember that your AA requires shell hoists and magazines below their turrets/mountings. Space has to be found for that as well.
