Re: A bomb that didn't sink Lutzow

Hello OpanaPointer, Did that movie also include the campfire scene from Mel Brookes' Blazing Saddles? It should have. :lol: Most of the flatulent gun slingers were less than 44 years old, so they would have appeared in die Grosse Fart. Some might have been babies at the time, so they could have don...

Re: Torpedo angle of attack

Yes guys, the control would ultimately fall to the depth rudders, but how? The rudders would push the tail down, so the nose will be pushed up, but that attitude would be maintained for all the travel, as the torpedo would constantly accelerate to the bottom because of its heaviness. The question i...

Re: Torpedo angle of attack

I do know that the special torpedoes used by the IJN at Pearl Harbor were modified so as to hit the water closer to horizontal.

Wouldn't gyroscopic stabilization keep the torpedos running level?

Yeah, I would have been more verbose if they hadn't come for me right then.

Re: A bomb that didn't sink Lutzow

The Tallbuoy remained unsuspected in the mud of the former "Kaiserfart" canal :lol: (German is good for jokes!) When John Wayne starred in his first big budget film, "The Big Trail" the production company shared expenses with a German film company that was making a similar movie. Wide shots and "ra...

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...
