RSAN units laid down or modified 1945

Disclaimer: Not sure if I posted any of these designs before. So bear with me if it is double or previously posted designs are a bit different. Lost most old data and tried to recover some. You may also get some hindsight of what will continue 1946+, though I maybe will not post reports for those years.

It does seem that a large number of craft are contemplated. However, many are rather short-range vessels. The purpose of the mix is unclear.

Well, at some point in time after evaluating events in South America and potential threats on the northern flanks in Africa I decided it would be good for the RSAN to have some amphibic component. There wasn't much available and with an unstable neighbor to the North of Gran Uruguay...

Idea is to have some low cost assets for short range activities if needed, while some bigger ships are made to follow international trends. Especially British dock ships impressed a lot...
The Glorieus is a direct results of the RSAN not having their own large transports. In some news during that war in South America it was mentioned that RSAN had to hire civilian ships to get their troops from Cameroon and other places to Uruguay. With that in mind I thought bying some liner that turned out to be too expensive for the line that originally planned for it, ought to be a good idea.

Anyways, I have no issues if you rate the RSAN approach to this topic kind of erratic. That's most likely a good evaluation after all. RSAN admirals see these things abroad but not on their ship lists. So they requested them... :)

IMO the Magnificent class are costly and unnecessary, and if built would have actually influenced Atlantean cruiser design significantly (Atlantis is into 1947 and still hasn't built any cruiser larger than 14,000 tons). Only the Chilean, Colombian and Mexican fleets have ships in that weight class, the SAE's more traditional enemies (Brazil and Argentina) have nothing close to this size that isn't a BB or BC so its unclear just why the SAE would need such large cruisers. That said if the SAE did build them it would likely spark Atlantean designers to dust off some of its larger auto 8" designs that were part if its current cruiser procurement project and makes its 1936 Neptune design look more useful as well.

Well, not sure if I can follow your argument here. RSAN cruiser design always was more evolution than revolution. Guess there is no despute. Hence I see that class more in line with the Radiance and Vengeance classes. In fact, they were meant to be upgunned Vs and although it took some time they were actually meant to counter potential threats like the British Iron Dukes than any South American designs, though these were evaluated too.

After the Thunderer and Leviathan class BBs it became obvious BB design somehow has reached a peak for the RSAN. There were bigger, potentially more powerful BBs out there and other nations were building lots of large carriers, the RSAN had only a few of, and older ones. And then there were some years where Super Cruisers were en vogue. How to counter them? Carrier doctrine was still in the making, experience late-30 or early-40s showed their value but also their weaknesses. A carrier, by that time, was not a reliable counter to a super cruiser gone raiding, IMHO. Heavier capital ships fast enough and with a decicive edge over a super cruiser were too costly if build for that purpose alone. If the RSAN would resume capital ship building programs, then those new ships would be made to counter foreign capital ships. Design studies showed they would be too slow to hunt cruisers. As a results, RSAN designers turned on improving their existing designs, giving them what was needed to either ensure dominance over foreign design or at least ensure mission kill capabilities. Add to that good and long experience with the 25cm calibre and there you are.

I agree it is unfortunate for you I provided my details so late. Sorry.

No quibbles from me, just nice to see some new RSAN ships.

The Magnificent Class are perhaps the pinnacle of the super-cruise vogue, now nations are mainly going for 7.5-8-9in autos to get the job done.
Amphib ships are always good to have, even Argentina has dabbled in this field. The RN should probably look at its provision harder.

I'm surprised that the SAE would base its need for super cruisers on British ships but I'm not going to quibble too much about that. I'll say though I'd expect them to build more carriers rather than super cruisers as their carrier fleet is aging rapidly and few replacements are being built. As for Amphibious ships, its not a fad for the SAE to build them, its a necessity for most navies now and it makes sense for the SAE to play catch up in that area.
