95mm is more incline to bend instead of spalling I think. to be precise MAD over magazines 100 mm (scarps 120 mm) Wh (Zeichnung Panzerabwicklung „Schlachtschiff F“ gültig für Panzerdicken, im Laufe des Baues geändert, Geheime Kommandosache) German homogenous armor plates possibly from from Tirpitz ...

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...

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 ...

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...

Warm welcome from me.

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...
