Re: Hood v Vittorio Veneto

I think, there is some misunderstanding here. I’m not trying to say that Littorio had weak armour. I’m trying to say that overall performance of that spaced array was not as great as 460 or 500 mm of Krupp Cemented single plate ( or what ever value ) Against British shells it was “slight better” tha...

Re: Hood v Vittorio Veneto

I do agree, but I haven't yet seen a final comparison table that can be universally accepted...... Me too. And I think it will never be done. To make thing the same, there is need to use various corrections, and recalculate tables. Sooner or later ( I think very soon ;) ) someone will state, that w...

Re: Hood v Vittorio Veneto

And I forget. In 1948 tests when attacked by 14" shell angle of impact 45 degree was used. So don't say that "on hull inclination" was ignored. It was 30 degree descend of shell +15 degree of inclination (or other combination). Structure gives no better protection than solid plate. Against British s...

Re: Hood v Vittorio Veneto

Once again about British tests Those tests in 1948 was later, than test of reconstructed Littorio’s plate. As it was discovered “slight advantage” of that protection, next series of trials were done to determine optimal configuration ( except distance between plates – that was constant ). Yes in tho...

Re: Hood v Vittorio Veneto

The British tests that you quote are flawed, as they did not use the materials used by the Italian or German navies, did not properly space the plate, and did not decline the plates at the historical angles used in foreign battleships. What exactly was flawed? External plate was 2.75” face hardened...

Re: Hood v Vittorio Veneto

Be very careful with data of performance of guns on navweaps.com It is various mix of data collected from various sources, but problem is that not always is stated what is source of penetration data! More – data for different guns are for different situations. In this particular example of British 1...

Re: Hood v Vittorio Veneto

there was no concrete in between, just air, to facilitate the "precession" motion. It is some time, since I have read Bergano’s “The Littorio Class”, so my memory could be flawed, but I remember, that “air” was between plates over machinery spaces. Over magazines that space was full with concrete o...

Re: Hood v Vittorio Veneto

the belt of Littorio's was inclined 15°. Sorry, by bad. I based on memory. But 12 or 15 makes small difference in reality, I think. More difference will be due to hull shape, or how many shells gun fired before action, so if will have more flat or more stepped trajectory. I know principle of decapp...

Re: Hood v Vittorio Veneto

Many depends of kind of shell striking plate. Post war, British tested decapping array. Short conclusion was, that if oweral thickness of that array ( main plate + decapping plate ) is more or less the same as caliber of incoming shell, than there is no difference between protection of such a array ...

Re: Royal Navy Super Battleships and Battlecruisers

You welcome. As I see some interest, I put part two. Before I put any new drawing, some long, boring text is needed, to fully understand logic behind those drawings. As soon as was decided that new battleships were needed, there were need to decide how they should look like. Design was to be started...

Re: Royal Navy Super Battleships and Battlecruisers

To understand logic behind those designs, You have to come back to the end of Great War. In 1919 started committee to investigate if battleship, as a kind of ship, is something that Royal Navy needed. There were some sounds, that battleship is dead. Future weapons will be light forces, submarines, p...

Depends how many splinters penetrated bulkhead.
One splinter is enough to make some flooding, and there is no need to kill anybody.

Re: Battleship Vanguard Armor

they would have been better off making Vanguard a 3 turret ship, and taking the guns and turrets from a Nelson class battleship. Actually Vanguard was 4 turret version of Lion. In early 1939 after examination of production capacity it was clear that limiting factor of starting new battleship is pro...

Re: Why was Rodney and Nelson so slow?

I think better question was "why Nelsons were so fast" ;) But seriously Nelsons were more ore less direct response to Colorado and Nagato. After WNT Britain did not need extra battlecruisers. Only ships of that class were in Japan – 4 Kongos, and Britain had Hood, Repeir, Refit and Tiger. Hood stron...
