Re: Royal Navy Super Battleships and Battlecruisers
I wasn't here for a while sorry. All designs I described were well before 1930 or so. Some experinece with diving shell existed (there were such a hits during Great War), but G to N class had very limited protection against such a shells. Some extension of belt over magazines, but none over machiner...

Re: Vanguard and Bismarck
I was away for a while. Sorry To be correct - first to designs inboard inclinded belt were British. On whole line that ended with G3/N3 (see description on other thread), that ended with Nelson. No such detonation on outside hull is not worse than on livin spaces, if ship is properly designed. Sure ...

Re: Royal Navy Super Battleships and Battlecruisers
Now, after some years, I found mistakes in my description about battleships.
All battleships designs were with two shafts, not four as I described.
I upgraded dragings, but can't attach here. Even 300 kb image gets "too large" message. Sorry.

Re: Vanguard and Bismarck
As I understand the main reason allies went to single deck armor plate was to defeat bombs, not shells. Both. Reason was simple. With increasing power of shells allies goes to conclusion that detonation of shells had to keep out of ship. Multilayer protection was designed in such way to force shell...

Re: Vanguard and Bismarck
BTW Americans used for calulation of deck 0.5*weather_deck + armour_deck + 0.7*backing So relative for Iowa would be 1.5*0.5 + 4.75 + 0.7*0.5 = 0,75 + 4,75 + 0,35 = 5,85 inch = ~147 mm if we add weather deck If not - some trajectories were such that shell could omit weather deck and strike just armo...

Re: Vanguard and Bismarck
That is sort of calculation I name „creative counting” Call whatever you want, but you are not arguing with me. You are arguing with scientists and engineers from Krupp and the Kriegsmarine, As should be obvious for everyone English is not my primary language, so possibly I misunderstand something....

3x3.3 m is tiny?
Then there were not any "not tiny" plates on battleship.
And there were more than one better plate.

Re: Vanguard and Bismarck
Slight? Armour the same thickness had 100 fs advatage on perforation limit, and was ~50 mm thicker,... There were no 5" plates to recover from Tirpitz. The closest to 5" from Tirpitz available at that time would have been from the 120mm scarps. There's the claimed difference: 120mm vs 127...

Re: Vanguard and Bismarck
No, AFAIK just a prototype that could never been used at the intended pressure..... Your source, please? 4 guns. According to Campbell. No mountings. Add: to be sure about which gun we are talking about. Lion 1939 was to be equipped with Mk II or Mk III guns. Slighty different in construction, but ...

Re: Vanguard and Bismarck
I forget.
those ranges at which olates were expected to be penetrated are from official documets. Not calculated by me.

In case of "unreadable graph" see this one https://www.dropbox.com/s/sc0b0fm3196xvb7/KGV_against_NC_SD.pdf?dl=0 I made only one with such principle to show "unknown area" and other important things. Still not all - turrets/barbettes for example nor forward/back bulkheads not incl...
