1. The breechblocks of our modern cannons and quick-loading cannons. The breechblocks of our ship's guns, which have been introduced since 1880, belong to the class of horizontal wedge breechches, except for the falling breech block of the 5.2 cm 8. K. L/35. Since 1889 they have been introduced as q...

even
if the original term QFG had no direct reference.

wrong it has "something" to do with the breech.

you have to shift the lower picture by about 1-2 m. look at the transverse bulkheads.

shared similar armor schemes. .... your description appears to short somthing more comprehensive: Excerpt from "Unterlagen zur Bestimmung der Hauptkampfentfernung..." Based on the experience of Worldwar I and as a result of the development of weapons, armor protection has been improved pr...

Armament Kreuzer Typ P Screenshot 2023-11-15 115900.png as the 28 cm turrets were not available the Kreuzer Typ P was transferred into Schlachtschiff Typ "O" May - July 1939 secondaries remain of the same type. in Addition ther is no 15,9 cm Gun in the Admirality manual for guns Screenshot...

MWa considers a dependence between (Seelenlänge)and relative muzzleenenergy and accuracy of a gun.

Its my opinion that Yamatos guns could overmatch the sideprotection of Littorio.

The thickness of the decapping plate could be insufficent against this shell.

Remember the german indication was approx 20% of caliber thickness.
I think we have a borderline case.

with regard to german radar for italian ships. The Germans as far as the available documents provide, never intended to give Feinpeilung and Messkette to the Italians;-->only the basic device. the german specialist wich visited the italian ships for preparation of installation of german Funkmess con...

As to the overmatch: At 10km vs. Yamato’s projectiles had a 6° angle of fall. At 5° Tirpitz side protection, the 320mm belt + 120mm scarp @ 68° from vertical + 45mm torpedo bulkhead, gave a LOS thickness of 631mm acc. Thorsten Wahl. A spaced array type protection is strongly dependend on adjustment...

Im not sure if protection of Tirpitz may be overmatched by the sheer size of Yamatos projectiles.

if they do then Tipitz is in grave danger

what means DZ?

Underwater travel of armour piercing shell was also subject of german ballistic research already before the First World War. they found abnormalities in the hitdistrubution on the target depending on angle of waterentry. German WW1 shells typically skipped from the water surface at angles below 15 d...

another comment no ship would attack at all costs. in a battle against other ships every ship may have a comfortable zone, with regard to own weapons effect and own capability to withstand damage. the own capability to deal damage strongly depends on firecontrol facilities. Maybe ships with more ind...

Most excellent! Thank you Thorsten! So the 28.7 km tracking range on Scharnhorst were done using the new TS6 diodes. But because of a wrong cooling installation the performance of the new sender was downgraded to the performance of the old sender (with TS1?). makes sense. i will compile the Funkmes...
