For Bismarck the volume of the 6 boiler rooms + 3 turbine rooms is 10,250 m3 (9,835 m3 without the cable alley).
The turbine rooms alone are 4,660 m3 (4,520 m3 without the cable alley).
boiler rooms + turbine rooms: 11,003 m^3
turbine rooms: 4,517 m^3

Re: Battleship Bismarck: A Design and Operational History

M I is machinery in regard of propulsion (boilers, turbines etc. but also smoke stacks and piping). M II is auxiliary machinery (for capstans, rudders etc., but also the heating installation). M II was 1400 tonnes IIRC.

2756 t for Bismarck (135000 hp at 58 kg/cm2).
This is from the weight List M I (2800 tonnes at 115000 SHP norm. and 138000 SHP max.) from Dezember, 30th 1936 including 252.2 tonnes water and 32 tonnes of 2 spare propellers.

Re: Battleship Bismarck: A Design and Operational History

No, I don't have primary sources to support my theory, but in my experience ship building is always a weight saving issue.

Re: Battleship Bismarck: A Design and Operational History

But Brooklyn wasn't a German warship. The German battlecruisers in WW I required 4 sets of propellers, shafts and turbines to be fast enough. Due to technological progress the German battleships of WW II required just 3 sets and were even faster.

Re: Battleship Bismarck: A Design and Operational History

IMHO the reason for a 3-shaft propulsion was simply the fact that it was sufficient for the required speed.

Re: Some questions about the battle at the Denmark Strait

Hello Sean, I'm sure that I'm right, unfortunately I can't find the document where I've read it. Anyway, the bars are only alongside the main artillery and in case of Bismarck also in the vicinity of the secondary artillery (height is about 35-40 cm). There are pictures of Bismarck with fenders and/...

Re: Some questions about the battle at the Denmark Strait

Besides the fact that the picture is heavily censored/retouched, I tend to yes.

Edit: There were small fences to prevent that the cartridges rolled over board, because brass was a very scarce material. After a battle they were collected and stored in their cases in the cartridge chambers.

Re: Some questions about the battle at the Denmark Strait

Taking into account a certain degree of uncertainty I tend to "yes".
