The Bismarck Tribune: Man gets 5 years in prison after drugs found hidden during Bismarck arrest
Man gets 5 years in prison after drugs found hidden during Bismarck arrest
Re: Bismarck and her contemporaries by Bgile » Wed 5:50 pm There seems to always be a significant number of duds when heavy armor is encountered. However, a dud can sometimes be even more damaging than a bullet which explodes. For example, suppose a shell failed to explode and instead was deflected through the bottom of the ship?

If Bismarck had trouble steering with propellers alone, other factors caused that most likely: Her big size when compared with P.Eugen? Convergent design of her propeller shafts? Did the Hipper or Scharnhorst classes have convergent shaft designs too?
Bismarck´s steam plant was a high temperature/high pressure on, at 58 kg/cm2, while the American´s was a little lower at 40 kg/cm2. Bismarck´s steam would attain a higher steam jet velocity, what would need a matching high rpm turbine for efficiency, which Bismarck´s single reduction gearing could not reach.
Bismarck's draft at 49406 tonnes = 10.2 meters. so we subtract 170cm from this @ 48.437 tonnes/cm = 8234 tonnes or 49406 -8234 = 41172 tonnes, which is less than I thought, but if we consider that Scharnhorst could make 29 knots with ~118000 shp, @ 39000 tonnes, this actually fits, considering the poorer L/B of Bismarck, so my estimate above, is a bit optimistic. Again, this only makes sense ...
