WesWorld

I know this ship can be considered a waste of money and resources, because obviously she cannot compete against most of the vessels already in service, either in Wesworld or in the real one.

She´s small, not too fast, but a hard nut to crack. Think of her as the best a secondary or minor power can get built. In fact Spain in the late 20s was considering to build 4 small BBs (23000t) similarly armed with 8-9 12in guns.

Well, since I´m not anymore an active player, you can consider this project as a private initiative, not backed by any goverment. Opinions?

Interesting, but you've pointed out most of the shortcomings already

Given my inability to run springsharp, feel free to represent yourself as Canadian Vickers or whatnot.

Why not a midships crossdeck catapult? It looks like the hangar is there already.

I did not use the midships catapult mainly for two reasons:

- I needed some place to put the boats
- And I wanted to space the secondaries, putting the catapult there would mean I´d have to move those two mounts and get them too close for my taste to any of the other mounts.

and I've seen worse uses of 20,000 tons.

I think the aftmost 20mm mounts are going to have a hard time from blast.

Thanks for your words, and yes I know those mounts are problematic, but at that moment I couldn´t find a better place, I was busy with the main superstructure...

BTW, for the people that likes a bit more firepower, those 8 12in guns can be replaced by 6 13,4in guns without any major change to the design. The only difference is that I had to get rid of the armoured conning tower.

Trying to post legible historical projects...



Historical RN designs from 1927-1929.

Note that the closest design has only 8x10" on 21000tons and 25knts speed.

Lovely picture but need HACS.

I knew I was forgetting something... I´ll edit the picture for tomorrow.

I envy your drawing skills, Gravina.... :o)

Is the hangar lift (or retractable roof?) large enough for a floatplane?

You all may remeber my attenpts at small BB.
After much thinking I ended up with a full size ship of the line.
So un intentionaly I repeted historical attempts at small BB.
Starting small and ending with a full size version.

Looks big enough, especially if it's got folding wings.
