need sources on the coastal batteries in Norway’s reload charts for a bug report for Gneisenau as the guns for gneisnau ended up there specfically her 15inch guns multiple sources say up 70 seconds for reload
her turrets are lighter weight models as they weighed 200 tons less than bismarck. they had more hand loading than automatic hoists like bismarck making them slower than bismarck as bismarck had 2.5-3 rpm and these guns would have had 1.5 to 2 rpm reload as they used more handloading and they where more cramped as Gneisenau
has smaller hull than bismarck and her hull was weaker which is why the turrets where built like this. also had reduced armor compared to bismarck
Did you read the non primary blurb you tried to use as a source?
Guns used in single coastal artillery mountings (BSG) in Denmark had very little power assist and were hand rammed. They are said to have had a ROF of one shot every 70 seconds. The twin mountings originally intended for Gneisenau but allocated for Denmark coastal defense would have had a ROF similar to the ships.
The single mounts were completely different designs that fired different shells then the twin mounts, you cannot compare them
What is your source that the turrets being developed for Gneis had a slower rate of fire and hand loaded hoists?
Gneisenau 38cm project has nothing to do with improvised coastal artillery mounts in Denmark and Norway. After Germans decomissioned couple of capital ships to boost the submarine wing, they just tried to use the spare guns from makeshift concrete bunkers. These mounts have nothing in common with original ship mounts, ammo storage, elevators and loading assists. Completly different.
There’s also that wounderful thing about unfinished ship projects: You have no real data and might always assume the best. See the Soyuz, the best battleship in War Thunder.
Also don’t forget it would apply for Sevastopol as well, so it won’t happen anyways.
