The bottom line is that nobody actually learned that aluminum was a bad idea for surface combatant superstructures through actual combat, and the only combat incident where aluminum actually materially contributed to the damage control problem was the Stark, where it was already known to be a problem.

The Royal Navy certainly had it figured out early on in the Falklands War. (Read One Hundred Days by Admiral Sandy Woodward). Sailors were sleeping up on the deck at night because they were terrified of being caught inside the ship in the event of an Argentinian air attack.

They already knew about it prior to the Falklands due to HMS Amazon’s peacetime fire a few years previous.
