As Captain Dove of the Africa Shell said to Captain Langsdorf, this is all on paper. It isn't battle tested, which would need a new version of the River Plate battle, where Langsdorf follows the long range tactics. I'm inclined to think that Navy Weaps is a bit on the conservative side, but of cour...

In german this error is known as Kantfehler. It was automatically corrected by the fire control system. The turret was trained opposite to the roll and the elevation was slightly increased until the barrels are occupying the same orientation within space as without roll.

Kriegsmarine destroyer captains were instructed to search for signs of use of radar at the enemy at least since 1940.

The Allies systematically achieved an absolute air superiority about the Atlantic past 1940/41 and continuosly increase the density of air reconnaissance. Only border areas in the north are partly excluded from this. Under such circumstances any attempt of a sortie of non air protected and air assis...

according this piece the ballistic properties were nearly the same. w.z.B.w.

In the other case we have a shell exploding next to an approx 4" bulkhead and another 1.5" bulkhead some distance behind it. It appears to me that there is a difference between these two cases. I question whether frags even get beyond the 4" bulkhead. Isn't that enough thickness to s...

I read somewhere that the hit occurs at around 4,5 m below WL, if i neglect a wave trough this depth is conform with ~15 meters underwater travel

What was the minimum thickness of plate to start the fuze of the british shell? in general the pentrated thickness for hit No 1 should be able to start fuze action, as it passes through 35 mm and 60 mm Wh as far as I can see; regardless from this, the beam of the ship was to low for a detonation wit...

I have marked the potential impact site with a red circle

front partial charges contain more wax to decrease impact sensitivity I think, but could be wrong, only in APC and base-fuzed HE. Nose-fuzed HE would have had a uniform composition throughout as there was no need to desensitize the forward TNT blocks, and since these were around the gaine, it would...

It is interesting to me how you choose a straight ballistics model with no comment about yaw in this case, where if you are describing In the case of deck pentration there are statements regarding yaw in the Unterlagen zur Bestimmung der Hauptkampfentfernung.... in other german and also in british ...
