[Okay guys, here's what's going to hit the waves in the early '40s. Keep in mind that these designs aren't even IC brainstorms yet, I'm just giving y'all a sneak peek as to where Brazil is going. The reason for the heaviness is because Brazil can't put the hulls in the water to compete with the major naval powers, so instead it's going for a high power/hull ratio. Btw, CanisD's CA2-D springstyle was a huge inspiration for the Amazonas.]

Couple comments:

For her displacement, she's not very well armed, or especially well armored, though she is fairly fast.

The small bulges are not going to provide much of any benefit vs torpedoes.

Try putting a transom stern on her, you'll free up a lot of tonnage for other purposes.

[Compared to the current crop of Brazilian cruisers, she's pretty well damned armed. Certain better armed than any other CA that she'd some up against and is well-armoured enough to slug it out with the new Argentinan BC. Anyway, here's the next-gen battlecruiser.]

[This one's interesting. The first design is a ruse, designed to make everybody think that Brazil's sticking with the 12.01" guns post-Cleito. There are minor differences, but nothing inconsistant with revisions or the standard understating of capabilities, at least until the main guns are put in and it becomes apparent that the new battleship isn't anything any one BB in the world wants to tangle with. Probably won't carry the name Brasilia into commission, though.]

Large Cruiser or Battlecruiser...it would be hard to call it a Heavy Cruiser, but maybe an Armored Cruiser due to her belt armor verses her main battery.

These, armed with the 12"/55 cal would be effective cruiser killers and could wound older battleships, or some of the battlecruisers, but would have to flee anything with serious armor and teeth.

The 14"/45 and 14"/50 guns on the other hand can be a threat to modern battleships, which is why Chile is going that route for battleships rather than the 340mm guns of the Nordmark built Lattores. Chile will not be replacing those guns like it really wants to due to cost issues. Thus leaving the 10" and 12" guns to the anti-cruiser work.

[Heh, you saw the guns on the new BB and BC, right? 16.73" monsters. I'm going to have fun building the new BB, just for the subterfuge alone.]

425mm guns...interesting choice. Like to see how you manage to get those built.

Though I doubt those guns will be alone in size by 1941.

Megalomania runs wild again.

I will be intrigued to see if Brazil has the resources and the infrastructure with which to tackle one or more of these projects.

[Filipino technical advisors.]

[As it stands right now, I couldn't build any of these ships even if my Type 3 was open. However, Rio is going to be heavily upgraded to build heavy fleet ships.]

I'd love to put my Kamatari CB against your "Maximum 305mm Battleship" and my Yamato BB against your "Super Battleship."
:-)

Sorry, I forgot who was advising you.

So how do these various designs fit into Brazilian naval strategy?

Mercinary Navy designed to hurt people and break things?

[Well, it's been pointed out that Brazil simply can't put the hulls in the water that other nations can. So, I've decided to build my fleet around a core of very heavy and very hard hitting ships supplemented by a swarms of torpedo boats and destroyers. In a way, it's taylored to the local environment because no other nation can match them on a ship-for-ship basis and in another it's taylored to the submarine heavy navies of the SAE and other nations.]

Your planing a Yamato...treaty maximum I trust?

Of course not

Super Treaty non-compliant 62,000 tons armed with nine 18.1 inch cannon in three turrets.


Hmmmm....I'll avoid hindsight on that one and stick to the nearly treaty sizes ship for my meglomania.

Well, the ship was treaty compliant until the ships were completed and the builders realized that the designers used imperial for the dimensions and not metric and metric for the armament instead of imperial.
"And we always wondered why those ships looked so big when we were building it..."

And who says that I will be building the 62,000 ton, 46cm armed version? I could easily go for something different like an Iowa design or perhaps a Bismarck design with 41cm guns

[There wasn't anything especially wrong with the Yamatos, it's just that when the USN took out their supporting fleet they died. Of course, that's the story of any battleship in the situation they were in.]

They wouldn't be alone now, with the Obukhoff 420mm/53 firing an 1150kg shell...
