I have problems in understanding british armour efficiency diagrams especially the vertical protection.
obviously they greatly understate the armour penetration performance of all guns versus vertical armour.
line in red minimum performance(Perforation, projectile whole and fit to burst) of the 38 cm Psgr according german fireeffect tables versus 14" FH armour
(even the performance of their own projectiles is not in line with armour testing.)
to make a difference; for horizontal penetration performance of the german gun there was good agreement between german fireeffect tables and british expectations in the upper diagram.
the armour efficiency diagram for Tirpitz completely ignores the additional protection provided by the scarp for vertical protection and the upper deck for horizontal protection
