The Ohio concept is a fabrication by WG, it’s design does not even exist in the form they produced it as, its a weird mishmash of around 3 or so designs and tillman turrets.
The A-150 by comparison is as possible as Montana as there are images of the gun barrels for the A-150 project in a field after the war.
Should add that the barrels were scrapped and used for reconstruction efforts so I guess that makes them not unique as they ended up being used for civil works.
The gun barrels dont actually count as major parts (because they are literally useless on its own) unless the breeches were also made, but it looks like they weren’t, and the ship was never laid down. Suggestions specify that they have to be MAJOR parts.
Oh tnx to both you, and @Lolman345 , I remember Japan had a few planed BBs that where converted to carriers due to pre war treaties, or lack of resources and combat loss during the war, I just got confused as to which ones.
And is that your quantification or the suggestion teams stance on the matter? Such sounds like a fantastic question to ask them since I’m pretty sure you do not know the answer to this.
