Re: Vanguard and Bismarck

In case of sinking battleships by gunfire alone I hardly find anyone (modern when sunk) if magazines not detonated.
Some Russians ships were sunk this way on tsuschima battle but other examples?

Re: Vanguard and Bismarck

I have always liked the Vanguard. The old 15" twins were good weapons and the Vanguard included many improvements based on war experience with the KGVs. Vanguard was also the first British warship built using extensive electric arc welding. And I alway hate Vanguard. I could see some of its advanta...

Re: Vanguard and Bismarck

Could You give data from live tests? I have boxes and boxes of documents. Unfortunately, because of my present circumstances they are in storage and they are not handy. Nonetheless, if I recall correctly the British study that found that no British battleship gun could defeat more than about 5-inch...

Re: Vanguard and Bismarck

Hi Maciej, is the Bismarck IZ diagram you posted above referred to the KGV 14" or to the British 15" gun ? The title says 15" but then you speak about KGV guns.... Hi. Bismarck protection is against 15" British guns using Cardonald shells with "new gun" muzzle velocity. I made a lot of various grap...

Re: Vanguard and Bismarck

If we thrust Nathan Okun research, IZ graphs should be more or less like this https://www.dropbox.com/s/q3mnjp6o1efz4ld/Bismarck_vs_Vanguard.jpg?dl=0 and on the same picture Bismarck, Vanguard and modernized Hood (after full modernization that never happen) https://www.dropbox.com/s/5f6xx96w08nwjuc/...

Re: Teleportation: H Classe in place of Bismarck

British 14" shell falls at 18.2 degrees and 476m/s at 18km. According to navweaps.com But it is for 2400 fs muzzle velocity, so with considerably worn out guns. PoW guns were new, and some of them had measured MV even higher than nominal new. On warships1 board Phill Golin put some time ago exact v...

Re: Vanguard and Bismarck

History turns circes. In 70thies of XIX century in Barnaby era, British build battleships with AoN scheme. The only real thred was heavy AP shot/shell so logic was quite simple. In early 90-thies of XIX century British recognized increased performance of heavy guns, and the same time thred from medi...

Re: Vanguard and Bismarck

In terms of firepower the Bismarck was more powerful. Its 15" guns were more modern than those used by Vanguard. The barrels were significantly longer which creates greater muzzle velocity. This translates into greater belt armour penetration and greater range sans supercharges. Supercharges were a...

Re: Vanguard and Bismarck

But Bismarck had better compartmentation, doesn't she? If so does that mean that she was harder to sink than Vanguard with the compartmention offsetting the advantages that Vanguard has, to say deeper belt ? Maybe Bismarck also had a better armor scheme below waterline to her advantage? I'm not so ...

Re: Vanguard and Bismarck

I wonder if a more powerful main armament could be installed on Vanguard. So with the TDSs being equal Bismarck should have had the better overall protection. In short - Yes. Vanguard was not what Royal Navy want, but what was possible with existing limitations. British wanted Lions (A bit shorter ...

Re: Hood v Vittorio Veneto

I don't want to start another thread.
I don't remember if Littorio lad centerline bulkhead through mahcinery spaces. Was it present or not?
So there were 2 or 4 turbine rooms and 4 or 8 boiler rooms?

Re: Serious design flaws in King George V class Battleships?

My last post in this topic. It become boring. M.v. IS the single most important component in perforation... Sorry Maciej. Oh yes. So why there were any development of new shells? So British WWI shells were superior to German at Jutland. For sure. Kinetic energy will not lie. Maciej, 16x133 is worse ...

Re: Serious design flaws in King George V class Battleships?

We are a bit off topic here, so taking some posts into new topis will be welcome, I think, but I add repeat here. ... If muzzle velocity is that stated on Navweapons, then the 16"/L45 MkII had the slowest m.v. of the ships enumerated - so it is impossible to have more penetrating power , at least in...
