I rephrase the issue of not counting (unhatched) eggs in a cockfight. Bismarck and Tirpitz were not ready ships at the operations in Norway. The only two "Modern" Battleships Germany had on the seas were the Scarnhorst and Gneisenau, actually listed as Battlecruisers. They prompted 11 inch guns instead of the 14-16 of the Battleships.
(I actually think the 11 inch caliber was quite a good weapon, but that's another issue)
There is quite a difference between launched and commisioned, not to mention being a part of an operation or not. Bismarck and Tirpitz were not ready at the Norwegian ops, nor planned for so, nor used at all. The Kriegsmarine had 2 Battlecruisers of more modern design in the ops and that was it.
BTW the date I have for Bismarck commisioned is 24 of August. That is more than 2 months after the complete capitulation of Norway. At least no misinterpration there. More than 3 months from the main operation though.
But, a misconception though...? From you:
"14 destroyers took part in the operation."
"Germany started the operation with four modern battleships, two WWI battleships, six heavy cruisers, six light cruisers and 30-odd destroyers."
Easy to misunderstand this. So, of 14 cruisers used they lost 10. There is then no myth about the German Zerstörer force coming back totally crippled from the engagements.
As for the age of the ships by the way, the German Destroyers were relaitively new ships. They were bigger than the standard UK destroyers and thereby sported more armour and firepower. Actually the bigger ones had about the same caliber as light cruisers.
Now for that one:
"The Allied navies also suffered heavier losses."
I asked first. I pretty much had the idea that the tonnege would fall unfavourable to the allies due to the aircraft carrier, which is like 10 destroyers in tonneage. But the slice of the pie falls like a doom hammer on the KM in relation. The whole play was about getting away with a cunning plan without risking a major naval engagement. They struck luck when sinking HMS Glorious, although the shooting gallery ending with a semi-phyrric victory (Both Battleships RTB due to damage). And they struck bad luck when Warspite busted them in bed. Takes some brass to put a slow WW1 Battlewagon into a fjord anyway, - the nightmare of engaging destroyers. So they were in bed probably. BTW, the Germans had arty on land already which got some shelling from Warspite.
Good to have the order of battle though. No misreading. Looks a tad different from the "operation" initially mentioned, which I am curious of what could be.
Good night to all
