Theres any number of 9.2" to 12" guns on the market for that matter.

Interesting

Interesting to see that I've sparked some interesting debates.

Sounds like many international representatives wish for the Oyama-class or similar design to be built instead of the radical (and controversial) Tylor-class.

I might have to oblige the nations of the world...but not without a few oddities. Interesting to note the sale of new arms is not restricted by the Treaty. Though the 10 inch/50 cal were originally going to be ordered from Vickers as there were the only company I know of that built such a weapon (for the Rurik). Most of the other arms were to be ordered from Nordmark, as those systems would be familiar. The 8.2 inch manufacturer was still not realized, as I don't know who has designed at 208-210mm/50+ cal rifle. For ease the design might have been reduced to a straight 8 inch model, either British or American. If the 8.2 inch is dropped altogether for 10 inch then that won't be an issue.

A thought I just had....what would the radical Tylor-like ship do if it was a tin-clad (aside from be shell bait) like many of its real world contemporary cruisers. This would allow for thin armor to be placed all over the ship, but would be vulnerable just like all the other cruisers in the world. The weight saving might allow for a more creative engineering design for the boilers and turbines, and perhaps a heat exchange system for the section between the magazines and the boiler rooms.


Of course the original idea for this cruiser was for a simple enlarged Blucher-like Armored Cruiser and then later an enlarged Rurik. The speed issue is what has enlarged this design into a near capital ship. The simple enlarged Blucher is only 625 feet long and does I think only 28 knots (17,000 tons). A similar version of this ship (older in style with coal engines) would have been proposed for alt-naval's Hispanic Federation instead of a Battlecrusier. This would have been only 505 feet long and had a speed of 24 knots (14,500 tons).

We'll see what Chile does in 1926 when the Type 3 slip is completed. However, more material will appear in this threat as more work is done and more comments arrive.

So...

BLÜCHERs uniform main battery was what made her superior to any AC ever build - for good reason.

However, BLÜCHER had some drawbacks and the most serious contributed to her sinking: magazins couldn´t be placed where they should be because of her wing turrets and machinery layout.

BLÜCHER also had a much higher bc to get a spacious hull form to allow those wing turrets. That´s also a reason why her dimensions were smaller. Try and use a reasonable block coefficient for your design and see what you get.

TAYLOR is far from being an enlarged and faster BLÜCHER, she´s an inefficient and less capable ship - relative to other ships of her era.

That´s it. Enough said.

Home now.

I'll pass around what I'm smoking later, once the new delivery systems are built.

It's an Armored Cruiser....what do you expect from a non-treaty nation? It is far superior to anything currently in the Chilean inventory, and with the exception of speed, follows the Armored Cruiser concept in a logical fashion (well the original concept did anyway). It does not follow the fashion of the world, which went to Battlecruisers and Heavy Cruisers once Battlecruisers became something you could not built.

As for the bc, what use it having it higher? I seem to not know the concept behind the bc standard. I was going for a lighter ship to keep it from being a battleship weight when it doesn't have battleship armor or guns. The majority of this ships weight is from her engines it seems, as the first concept was about 17,000 tons at a reasonable 24 knots. Would not a destroyer hull form be for fitting with a higher speed ship?

I might play with the three designs again, but the original concept was to have 16 main/heavier guns to allow the vessel to potentially target two ships at once in a era with no radar. 8 guns seems to light to me, even if they are 10 inch guns. I might go with the Libretad concept instead of the Tylor, and replace the two centerline triple 8 inch for twin 10 inch gun turrets. or a single triple 10. It should fit on the deck fairly easily...I imagine SS with say it will work for the engine as well (as it does for the Tylor), though my drawing of it might not suit the actual needs of the engines.

"Would not a destroyer hull form be for fitting with a higher speed ship?"

Indeed, but do you think the fine lines of a DDs hull provide a hull bulky enough to install heavy machinery and heavy armament (barbets/magazins)?

They are all much better than their predecessors.

12 guns in 5 mounts on Libertad? 3-2---2-2-3?

I'd lose the 150mm guns and just use the 110mm gun (4.33" not 4.3")

Do you know RTNS Sans Souci from Tarrantry? She would appear to be what you are after, just smaller and cheaper. 18.000t 32knts+ speed 12x8" guns, 190mm-150mm belt and 115mm-125mm thick deck armour.

Wow, talk about a resemblance between Sans Souci and the Atlantian Vengeance class BC's!

I agree with RA on this one, the perfect design for a fleet looking to gain an edge in the South American theatre.

12 guns in 5 mounts on Libertad? 3-2---2-2-3?


Yes. The original 13 guns in 5 mounts was too unstable for the ship's mass...so the 3-2---3-2-3 was dropped, as was the older concept...14 guns in 6 mounts..3-2--2-2--2-3.

10 inch guns somehow suit my thoughts more than the 8 inch, since the only reason the nations of the world did not go higher than 8 inch was due to the treaties. Without the treaty, as we saw in WWII, the guns sizes would increase to that of the previous generations' battleship guns (Alaska-class).

Tylor will likely be laid down in Q2/1926...we'll see what happens after that. Though expect the unexpected...at least for the Tylor.

That drawing is by Fantasque, who is one of the "Big Five"; wb, Theodore, Rick Robinson, Lord Herrick ( i think)

Lord Herrick has done most of the cut & paste drawings on the website. Fantasque is a teacher at the French école de guerre (or School of War), and so he knows quite a lot more about ships. He has done a few small ships' covers and designed a few ships more accurately than with Springstyle.

Fantasque and I were arguing a bit with the others about Sans Souci. We wanted to go with a mini-Hood whilst some others had a more american influence. As it ended up, she now has smaller Hood hull form. He punched a few numbers in and she can actually make 35knts on 120.000shp after her US refit.

If you want more drawings, best thing is probably to post a message on the Naval Fiction Board.
