Just some ships I did on a whim, with help from our favorite Scourge of the Pacific. Whether they are built at all, much less in '42, depends largely on just what my priorities are.

Are your two midships 6" turrets supposed to be amidships, or are they supposed to be on the ends?

They're part of the superstructure; the amidships mounts are more towards the ends of the superstructure, but I'd still classify that as amidships.

Heh heh

Do you want me to try to outclass those, or have a cheaper (and slower) version?

If you want them to superfire the main turrets (like the RSAN Ophions, for example) they'd be end mounts. If they're in between the fore and aft superstructure, then they're amidships.

Frankly, I'd feel better if you could outclass both designs.

Okay, I understand now. Thanks.

Three ships in SS (though I can't say I will build any of these three) I suppose I'd build two of one or one of two classes, either to replace the pre-dreadnoughts, or the dreadnoughts.

I might modify the designs to reflect secondary and other small weapons changes Chile goes through in the next decade.

Oh and these obviously don't outclass the Brazilian ships, but they are either cheaper or have a larger main gun.

Isn't it though....gives you a reason to build them in 1942.

Dreaded Monster of the North™ to keep the South Americans awake at night

I thought that was the job of the United States Navy.

Though this Great White Yamato might be something, I know the Japanese have got better up their sleeves.

Chile's ships, at least the first two are probable as replacements for the exisiting battlewagons, the third is possible, but a little too expensive for Chile at present, especially with the Oyama-class building.

ShinRa: I'd work on the seakeeping, if I were you. Can't see that thing making it out of the North Pacific or North Atlantic without some ability to ride out rough weather well.

Ithekro: Meh. If things work out like I hope, I'll start closing the gap, at least in terms of modern hulls in the water. I have a feeling that you'll always be ahead of me on a one-for-one basis because of the generation gap.

Not quite sure how to improve seakeeping for it. I also seem to have forgotten to put the range on that version, and now I'm trying to get the longitudinal strength back up to 1.00

As long as we are defending our respective Oceans, I don't see a problem. Chileans in the Pacific, and Brazilians in the Atlantic. Ample coverage for the continent against treaty battleships and treaty cruisers. If the treaty holds the South Americans will have superiority in several types of ships, but will forever be out numbered by the Treaty nations...but that makes sense logically. If you can't outnumber someone, make something that can outfight them one on one or one on two if you can.

Try bringing the speed down to 28 knots or so. Big gun ships like that can't be fast battleships.

My big ambition is to gain a Pacific coast, however any fleet there is likely to be my backwater/reserve fleet where old ships that are still too useful to be scrapped are sent.

Interesting, there are 4 nations that Brazil would have to tangle with in order to gain that Pacific backwater fleet. Colombia, close to Atlantis. Equador, close to Iberia (presumedly). Peru and Chile round out the list.

As for the individual ship superiority, that didn't help Yamato as much as the Japanese hoped.

Well, I'm not going to give too much away on how I plan to gain a second coast. However, given how much we've talked, you can probably guess how I'd do it.

As for the Yamato, it was sunk by aircraft after Japan lost most of its carrier force. Given that Yamato's AA defenses were, um, rather pathetic, it isn't surprising she was pounded into scrap.

Acctually her AA was reasonable, the lack of carriers is the more presise reason why she was sunk, as were the Prince of Wales and Repulse. The lack of air cover meant the BB's lacked the only true weapon that would counter aircraft effectively.

Yes. Muteki Nippon. :-)

Seakeeping should improve when you add range. A lower BC will also work.
