More progress worrked 8" 40s three forward 2 aft Note spnsonsns only have ninty degree travel rang. Note gave guns 45 degree elevation if desired have to work on side view but after eight hours looking at dotts I'm seeing them ;)

Yes she has portholes, note some are open and some closed you see single yellow dot it's a cover closed and locked, if there is blue porthole and lid to the right it's open.

Some problems:

1) The lines is too abrupt. And the fact that superstructure sides are dircetly connected to the hull sides isn't wery usefull: it just make additional problems for seamans.

2) The two-level sponsones is, probably, not a good idea. Yes, they were used by some navies, but they are heavy and crampy.

3) Not enought desk air vents for the hull so huge.

More design, first the Big Guns note six foot tall man:

You have to design what goes in Barbette or sponson before you can design them, You've seen the Barbettes now a Sponson:

Under the 1.5 deck sponson Dilandu how about water tanks: to use the space ;)

15 feet is the minimum diameter to fit the 8"/40s

As I understood it most older ships had portholes because there where no forced ventilation and without those portholes it would become unbearable hot below deck (depending on the weather ofc).


No, the problem was simply a comfort. Crews, locked in the porthole-less metal box wouldn't be exactly happy about that.

Moders warships has less portholes as the anti-nuclear precaution, not because it somehow affect ther integrity.


Agreed, but with a couple of caveats.

Lack of ventilation did create significant habitability problems, which is one reason sailing warships spent so much time with wind scoops rigged to direct wind down into the interior of the ship, Powered ventilation did make a significant change in that respect.

More to the point, perhaps, one wartime discovery was that scuttles (portholes) increase flooding as a ship settles deeper into the water. As a result, you will see no scuttles lower than the "flooding deck" (I use that term for clarity avoiding a whole plethora of technical terminology), or the boundary deck which is supposed to keep the core compartments and vital systems unflooded and protect the ship's essential buoyancy even if other compartments higher in the ship flood.

One of the most telling comments on the thin armor of the last 2 WWI BCs of the British Grand Fleet (Respite and Renown) was that when they arrived at Scapa Flow "The scuttles in their hulls revealed the inadequacy of their single strake of thin armor to all the world."

It's also worth looking at the Russian (Hey, Dilandu!) Imperator Pavel class battelships laid down in 1903 or 1904 but heavily reworked post-Tushima. Some of the Russian ships lost there flooded through their scuttles as they took on water through other holes in the hull and settled deeper into the water. The Russians responded in Imperator Pavel and (I think) Andrei Pervoswani (sorry about the spelling, Dilandu; I'm shooting from memory here) by eliminating all scuttles from their hulls. And, IIRC, both ships enjoyed a reputation (deserved or not; I have no supporting documentation either way) for being unhealthy vessels because of that. It's worth noting, however, that IIRC, no last-generation USN battleship (all designed in the 1930s and 40s, well before the atomic bomb was more than a gleam in Enrico Fermi's eye) had portholes or scuttles in the hull at all. I may be wrong about that, but I don't think I am. If anyone has more ready access to his reference books than I do and can chime in to correct me if wrong, I'd appreciate it.

Yeah, they was't good in that therms. ;) Their engineers was so worried about the effect, that HE shells may have on their unarmored parts, that they simply armored ALL battleship's hull instead. However, it was not a good idea, as it turned out that their impressive armour area was too thin to stop the heavy AP shells that became the main instrument of dreadnought's long-range warfare.

Engine room KH VII four cylinder Uni-flow triple expansion engine, two HP cylinders cranks set ninety degrees allow starts with no dead spots where you would need jacking gear to turn the shaft by hand. exhaust from HP cylinders goes into blue receiver tank to power mid pressure cylinder, exhaust from mid pressure cylinder goes into yellow receiver tank to the Low pressure cylinder. The exhaust goes in green pipe down to the condenser in the bilge green line going up is heading for the vacuum pump. Larger diameter pipe on bottom collects condensate separating from vacuum exhaust steam.

Space above for crane to lift massive cylinder heads. Information on various marine steam engines here http://en.wikipedia.org/wiki/Marine_steam_engine and the uniflow type here http://en.wikipedia.org/wiki/Uniflow_steam_engine

No way! The engine MUST be inside the citadel, or for what reason you have a armored belt at all?


No one real ironclad or battleships ever have engines in the rear! One good shot, and all the engine would be out! And they are heavy, real heavy.

The engine must be in the citadel.

P.S. And if i remember correctly, the RFC stated that the berbettes go through the hull down to the armoured deck.

You are going to run the shafts through the rear magazine? Yah smoke a bearing in there and a big boom! drop a shell on the rotating shaft for even more excitement! Most of the engine is below the water line add a little armor if you are paranoid.

Sigh.

The ship has two screws and two shafts.

They are nowhere near the rear magasine.

For good example:

Please, show me ANY battleships with such ridiculous engine emplacement. I couldn't recall any.
