Lessons learned to be sure, but as I noted elsewhere, Lancelot Holland, even with such an improved Hood, had to make the SAME tough choices to catch Lutjens and bring him to battle. The Battle of the Denmark Strait could have gone the other way IF Holland could have turned sooner and brought on a parallel fight at belt punching range as he wanted.
Some of those choices would be to hang back and shadow or wait for his cruiser destroyer support, but in those seas, that meant he would have to reduce speed and might lose the Bismarck. Other choices were to angle the merge less acutely, but again that would mean a longer chase and in the sea and weather conditions prevalent (especially the poor RADAR weather) Lutjens might escape him by a turn east.
There really was no magic "solution" I see that helps alter those fundamentals except the PoW being worked up properly and being better than SHE was.
Hoods FC is higher up, and obviously an Admiralty FC rather than the Dreyer V. That alone may aid in correctly spotting Bismarck compared to mixing it up otl.
Then you've got gunnery. Hood landed her first salvo just off Prinz Eugens bow before changing to target Bismarck and working back to find the range. If she's targeting Bismarck from the start, you've got a good chance of hitting early on.
Next point, Bismarck’s golden BB. I had an entire argument with someone about where it was likely to have hit, probably through the upper belt and through the bend in the "turtleback".
With the deck armour extended out to the inner hull wall that won't happen.
Suffolk and Norfolk aren't that far behind, but Holland needs to slow the germans down for the cruisers to catch up.
If Hood lands hits on Bismarck early enough she could pull a Rodney knocking out FC and turrets. Prinz Eugen needs to be dealt with, british battlecruisers had a knack for dodging torpedoes, but yeah I wouldn't want to risk it.
Simultaneously I can't imagine Hood handling the hits PoW took, but she can presumably fire back unlike PoW. Going to be a pretty gruesome knife fight if Lutzens doesn't try to run.
Worked up PoW is a big game changer, 18 heavy guns firing consistently and (pretty) reliably at Bismarck at PE isn't ending well.
