If Hood had defeated Bismarck

What lessons and consequences would follow if Hood had defeated Bismarck?

Hood would likely have become a celebrated and upgraded ship whose prestige made postwar preservation much more plausible.

A victory over Bismarck would have transformed Hood's reputation and the lessons later observers drew from her design. The Royal Navy would likely modernize her and treat her in a manner comparable to the celebrated Warspite. Operational success would strengthen the political and public case for retaining the ship after the war. In this counterfactual, battlefield prestige becomes a material factor in reconstruction priorities and museum preservation.
