Re: PoW's gunnery VS BSM's gunnery

still showing that the "green" PoW had the pool of personnel in the royal navy was significantly larger than it was the case in the Kriegsmarine, the core of personnel came from older battleships. So a "green" crew appears questionable. Both german crews were also "green" in this context. @wadinga ...

Re: PoW's gunnery VS BSM's gunnery

We can derive from data, that if target and /or own ship changes course, speed and so on, an automated firing solution seem to lag somewhat. It requires additonal observing of target movements and additional manual corrections to overcome the potential error by lagging. Experience(how the whole syst...

Re: PoW's gunnery VS BSM's gunnery

Between the closing of the firing circuit and the Moment when the shells leaving the barrel, ther is some delay, so it requires some correction. And this correction is the Vorzündwinkel, wich describes all variables involved in the complete process (for instance ship movements, delay of the electric...

Re: PoW's gunnery VS BSM's gunnery

My sense of it is that Bismarck would have been equipped with remote power in train. The main firing procedure uses Höhenfernsteuerung mit Seitenvorzündwerk "remote control for train with Seitenvorzündwerk" "Seitenvorzündwerk" is a uniqe german feature, not used by any one other nation in this time...

Re: Target data

Nice reference from Thorsten too. Wonder how they knew black line "true" distance? Were both ships running on surveyed-in railway lines for instance? both ships were observed by shore "Langbasisgeräte". Accuracy of the Langbasisgeräte was significantly better then the usual range measuring devices ...

Re: Bismarck Alternate Propulsion

... So maybe a Bismarck-heavy ship, longer and thinner (30m maybe?), with 2x4x35/38cm in order to fit (and save weight) 16x12MZu42/58 large diesels on 4 shafts for 144.000hp? With triple 15cm superfiring over the main turrets achieving the same 6x15cm broadside as IRL. Hopefully 30kts might be achi...

Re: Bismarck's armor against long range hits

1) against 50 mm + 80 mm ther were several perforations on Scharnhorst(La Pallice) and Tirpitz (Tungsten)but no detonations the double impact on wheather deck and main armor deck obviously rendered all fuzes from 1600 lb armor piercing bombs into duds. 2) against 50 mm + 110 mm all bombs that hit br...

Re: Bismarck construction flaws

I always wonder the slop portion of bismarck's turrets is weard. Is it too light for 180mm at such an important place? whats the distance you expect a penetration. the forward 180 mm slope had a projected hitable area of maybe about 100 m² at 10 km. for Bismarcks guns the 50% zone of impacts at 10 ...

Re: Richelieu and Jean Bart

Decapping would obviously increase resistance, but by how much I'm not sure - so I'm not really sure how to judge it against against a single-thickness deck. the problem appears more difficult. and ist not only the effect of decapping one has to taken into account. If protection is increased or not...
