Re: closing up bismarck during daylight action

I don't think any WT doors on naval vessels are or have ever been electrically operated. To my knowledge they are all hand operated. Certainly every ship I've visited was like that, as were all the submarines I served on. They all required a sailor to shut and dog them, and the same sailors could op...

Re: Pom pom with director Mk IV vs Bofors 40mm with Mk 51

Well, a circular screen of an HVT would have the screening ships often less than 2,500 yds apart, so well within 2500 yds and attacker would often be trying to fly between the screening ships.

Yes some deflection, but nothing like that required to engage the same aircraft attacking a different ship.
True, but of course you would be trying to do that as well.

A torpedo bomber would not be flying directly at the ship. There was quite a lot of lead involved.

Re: 3-shaft propulsion

You could also look at the Montana/Midway powerplant layout. They have a four shaft arrangement where the after engine rooms power the outboard shafts and the forward engine rooms power the inboard shafts. This results in an arrangement where the long shaft runs go down the ship's centerline instea...

Re: Redesigning Bismarck

IIRC when the IJN tested Yamato's aux rudder they couldn't turn the ship at all with the main rudder centered. It was essentially useless.

Power is not measured in MHz. I'm guessing Kw?

Re: How close was the final battle?

Hello Mr. Crandell, you write: "Then why did Bismarck stop firing when she had to maneuver to avoid the phantom torpedoes reported by Prinz Eugen?" Bismarck stopping fire is highly unlikely. We don't have any image for Bismarck turning to starboard to 'avoid torpedoes', but we have PG fil...

Re: How close was the final battle?

My two cents on how close the last battle was: Not close at all! Two versus one is a clear thing on my mind: Lets say, Bismarck's shots get too close to Rodney's liking. Rodney starts to chase salvos, i.e. maneuvers defensively. This denies Bismarck to get hits on Rodney, while Rodney also has trou...

Re: Gun precision / dispersion

I believe full salvos (in the US case nine guns) made it easier to determine MPI on a late war PPI display.

Byron, wow! I hadn't thought of the different weight measurements. Good research!

Re: Size of French Naval Artillery

I believe HMS Victory had two 68 lb carronades in her bow for the purpose of blasting the opposition's deck with grape shot at very close range. I believe even Victory's gun deck had "only" 36 lb guns in the broadside. They tried 42 lb brass guns for a bit and they turned out not to be pra...
