Re: British v German rangefinders

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.

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

Re: Jasper, Schmalenbach and 6 salvos...

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...

Re: Jasper, Schmalenbach and 6 salvos...

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...

Re: Jasper, Schmalenbach and 6 salvos...

To start: I didnt follow this thread actively. But the Picture "Bismarck feuert seine erste Voll-Salve" appears as -at least- its second salvo to me. Its strictly my opinion, the smoke that can be seen near the aft turret cannot be from PG as the blast from the shooting would move it to port not beh...

There seems a typing error in several documents regarding the distance of the Denmark strait battle 290 hm should be 208 hm correct value can be found in Akte Unternehmung der Kampfgruppe Bismarck zum Handelskrieg im Atlantik Funkspruch 25 Mai 1941 Uhrzeitgruppe 0401, 0428, 0417, 0443 ...

Re: Battleship for Freedonia

Where is Freedonia situated.

Atlantic - Pacific.

Does Freedonia require limited rawmaterials (Iron, Steel alloys, oil) or is it a exporter. Are there antagonistic interests to anyone?
