Re: Secundary guns turrets

The new Bismarck´s book mentions that a secondary turret´s crew became locked in their post because the turret scuttle was deformed and could not be opened. Why couldn´t they escape from below deck?

Re: Secundary guns turrets

Marc, in Brower´s book there are two scuttles in the barbette, they do not show up in your plan. Which is correct?

Re: torpedoes

Here is the article of the Argentine project, it was developed by an Italian engineer that had made something similar during the war. Sorry it is in Spanish, but there are some pictures so you can get an idea of the device, the engine would be an DB605. https://issuu.com/archivohistorico/docs/revist...

Re: Main armament hoists

Admirable synthesis! Thanks! Was there any manual backup for either (I must admit that there would be difficult lifting about a ton 15 m by hand).

Re: torpedoes

About radio guidance for torpedoes, yes, there is no way for this unless you deploy an aerial above surface. Anyway, here in Argentina somebody tried exactly this, radio guidance and (stranger yet) explosion engine propulsion, air admitted via a kind of snorkel, will look for pictures. It had a larg...

Re: torpedoes

Well, long range torpedoes use mid course guidance thru a cable, receiving target data from the parent platform, the torpedo onboard sensors have not the space for the sensitivity needed for a 50 km detection. I must say that I am in a mistake with this, the wonder-propellants were not available unt...

Re: torpedoes

Yes, but not every navy had a CV, so you can say that there was a need for the the torpedo yet.

Re: torpedoes

I have ever wander about this. Why the surface torpedo disappeared? Nowadays it is clear that missiles are faster, but back in the 60s there were almost no anti ship missiles aboard, while the torpedo had already evolved to the guided monopropellant powered device that gave them about 50 km range wi...

Secundary guns turrets

Hi. In Bower´s AOTS it can be seen that the forward turrets had an under deck structure, just like main guns´ ones, with a lower shell and powder room. The four after ones do not have this. Were the loading arrangements different between both?

Main armament hoists

Hi guys. I want to clarify this. How many hoist there were in each turret? What was the motive power of each? And which its function?

Re: Battleship Bismarck: A Design and Operational History

Thanks Bill for your answer. Couple more things I really do not like: -guns calibers en mm, I understand this for the Germans, but do not for the British, for the sake of historical accuracy the originals caliber designations should have been used, ie inches for the RN -the same with the distances, ...
