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...

Scharnhorst had 320 mm belt.

for Germany the optical rangefinders at least on the capital ships were triaxially stabilised. A feature wich was recommended by NavTecMisEur also for use on american ships.

Weapon how about a 38 cm SK C/34 with 865 m/s and elevation 35 dgrees from a early design study. Range about 42,5 km Flightime 85 sek impact velocity ~500 m/s at 20 km the shell should be about 25 m/s faster then the Vo 820m/s Version. and somwhat mm more penetration versus vertical armor plate (~44...

Hello everybody,

@ Thorsten Wahl,

Bye Antonio

Turret D is trained nearly 90 degrees it should be about 45 degrees forward to fit the early time.

Few little things regarding reliability of timing of PoW -- My problems with wording and timing POW 05:37 Enemy sighted range 38000 Yard The rangefinders failed to develop a satisfactory range plot before opening fire KTB PG enemy sighted at 05:50 at 30 km obviously an excellent performance on the b...

I see what you are saying and meaning. Whether report for the time says north westerly winds - force 4 (means 5-7,9 m/s) this is almost right angle to the course of the ship once a puff of smoke is released and lost ist initial propagation velocity, hes driving with the wind 10 seconds after shoting...

they produce a indentation.
If memory serves this happened to Seydlitz during the Jutland battle 1916.

I suggest you to carefully look at all the other photos of the German squadron during the battle and at the very famous Schmitz-Westerholt paint of the salvo that sunk the Hood in order to realize how the main guns smoke was leaving the warships behind them, 210 kg RPC 38 nominally produce about 20...

oh my fault 290 hm = Feuereröffnung british ships thx -----nevertheless completely incomprehensive for the timing if distance at 5.50 = 30 km given the approach velocity of 1450 m/min 290 hm should be reached within less then one minute but the 3 mins from KTB give us about 4,35 km distance shorteni...
