I think to remember that on "Scharnhorst"'s triple turrets (whose guns were fired usually within the same salvo) the central gun fired first, followed (within 10 to 20 milliseconds delay) by the lateral ones. I don't know whether delay coils were implemented on Bismarck's too. Bye, Alberto Delay co...

its the same.

but sometimes if you use muzzle energy, it may be confound with muzzle velocity and
weight of propellant charge is more intuitive to energy I would say.

In this case, the angle of fall indeed appears to be about 19 degrees, but the projectile is shown in plan (why are the views not aligned?) as approaching from 40 degrees forward of the bow. A bit of mathematical (or geometric) manipulation, which I will not go into in great detail here, indicates ...

There may be some confusion here from the DS battle, where one of the three hits by POW did penetrate a boiler room, where five stokers suffered serious scald wounds. The shell dived under the belt approximately in this way and detonated in the proximity of the torpedobulkhead -blue -E-werk out of ...

I made also a visualisation of the E-Werk hit uncertainty of UW trajectiory has to be observed. projectile probably hit the static wave trough generated by shipmovement the 12,5 m distance is determined by the likely arming distance for the british fuze as the projectile detonated at contact with th...

More importantly, there was a loss of more than 1000 tons of precious fuel. Fuel tanks had been contaminated by seawater, and the fuel distribution system forward had been seriously damaged. the projectile obviously damaged all watertight walls on its way through the ship my conclusion from descrip...

My take is the Japanese had better observation of the destroyers and targeted them, leaving the two BB outside the clusters of torpedo tracks. The Japanese were 100% dependent of visual observation and the slightly closer destroyers may have been clearly identified first, leading to them as the aim...

Regarding the POW salvo plot
this chart contains distances, but these distances are not the distance as measured by the rangefinders, but the distance of the expected shell travel from the firing solution.

So Campbell's account said that Bismarck's 3rd salvo from the fore turrets, just before Rodney obtained 1-2 hit(s) on them to take them out of action achieved a 'perfect straddle' with shells landing, fore, aft and to both sides. In short, he seems to have described the shells as almost hitting but...

its my opinion that decapping was a new feature to the Kriegsmarine in 1935/36 but well established in about 1938/39.

I could find a armor schemes for H-Class and also for P class cruisers using a decapping plate + main FH armor plate for vertical protection.

One wonders where the 350mm number comes from if not original docs (alternate version?). From Erich Gröner "Die deutschen Kriegsschiffe 1815-1945". During WW2 he was responsible for type recognition foreign marines. In a early stadium of construction 350 mm was primarily choosen. But weight restric...
