Re: Officers of the Kaiserliche Marine

I suggest Holger Herwig's Luxury Fleet. Available on Kindle at Amazon. Been 15 years since I read but his research notes should provide some breadcrumbs for you. Thank you for the recommendation, I had been concerned Herwig would be too general, glad to see it might be more useful than I thought. T...

Re: Was the battleship Bismarck really the best of its time?

Verily. Compromises are the fact of life. Protection + Mobility + Defense = 1. No truly 1/3 + 1/3 + 1/3 warships out there? Even if there are, is that a good idea?

Re: Broadsides

The stress of the cannons was factored into the design. I don't know of a loss due to recoil shock. https://www.historicnavalfiction.com/ge ... g-a-cannon

Re: Ships boilers

Many thanks for your reply, what is a 'pit snipe' and how did it get its name The "pit" probably arose from Dante's Inferno. You go down, down, down, down to get there. And it's hot as hell most of the time. In the coal fired boiler days that doors had to be opened to add coal, so the heat gradient...

Re: Ships boilers

Gentlemen, Not sure where to place this, but here it is anyway. A question I have often wondered about, when a ship sinks could the sudden rush of cold water cause the boilers to explode? With an internal pressure of (up to) 1200 psi and temperatures of (up to) 900 F and a sudden failure of the str...

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 lar...

Re: Ships blowing up when the rolled over

Thanks for your replies, i believe Scharnhorst actually blew up underwater after he went down, perhaps there were still fires burning new the magazines? The powder has its own oxygen, so a sealed compartment that is subjected to great heat (such as compression by dept of water) could cause the powd...

A triple tube mount doesn't take up much space and it's another string in the bow.

Re: Ships blowing up when the rolled over

As far as I understand things, it is not the shells that explode in a magazine explosion, but powder bags. A ship that capsizes has taken heavy damage and may have some fires aboard. These fires as well as red hot fragment can ignite these powder bags. With enough powder to fling many large caliber...

Re: Jammed rudders and damage to prop shafts

I was on a guided missile cruiser that experience a rudder failure back in the '70s. Luckily this wasn't in confined waters, unless you consider the Panama Canal to be such. The skipper was about to beach her to avoid damaging anything when the glitch cleared itself.
