While yes this is not a weapon, or even something you expect in that matter, i have comes up with my entries, this is 3 hulls with turret location shown by the black spots

In the left side we have a reversed Dido Class Turret Arrangement, this is also originally HMS Dreadnought planned design
.
In the right side we have the origina HMS Dreadnought Turret Arrangement, with 1 extra guns, that is how the turret were arranged in HMS Dreadnought
.
And then
In the middle we have what appear to be Admiral Fisher being drunk, stating "lets put all the turret we can have on a single ship, so there you go, that's the abomination that you have built

Now, even though the middle turret arrangements is already ridiculous enough, one of my ship..., now non canon on my remade timeline, is the Fantasma Class Super Dreadnought, that thing was 37.000T in displacement and it has 10 Turrets and 20 Guns, ABXY Configuration on the first 4, the ABXY is a normal centerline, and then you have the very unorthodox part of the ship, wing turret, 3 of them on each side, the freeboard so low that your casemates (which is a hell to make) is flooded with a spray of refreshing sea water, except its a spray times 1000x

Something that i also want to originally build, is 6 or even 8 guns turret, its thicc af and as wide as Yamato Space Battleship lenght (metaphorically)
.
The others is something that i think Kerlowo will be very mad at me, yes, indeed Kerlowo, its a Gast Gun, but the caliber is 16-Inch, oh god, i have a feeling im gonna get scolded by that fox XD, because realism forbids i rather not, im still mindfull about realism, despite not too much, but... Eehhh... You know what? Close enough to be counted as "realistic"

Anyhow, there's nothing else that is special, only some turret arrangements template, maybe you want to build a ship like the middle one, i don't know
.
If this were not WW2 Only Challenge, i would have gone ahead and pull up my Super Graviton Cannon and Wave Motion Gun, Anime's Strikes Again Damn It
