I take your point about lessons being forgotten, because they always seem to be, but I'll disagree with you if I may.
The sinking of HMS Prince of Wales and HMS Repulse serves to show those that do not change with the times that obsolescence in warfare can be very painful.
Does it show that ships are incredibly vulnerable to air attack? Well, no. It shows that they were. The RN believed in the battleship whilst modern and excellent brains such as Mitchell knew they were out moded. But times have moved on again, as they tend to.
Maybe those that think an attack by manned aerial systems (aeroplanes to you and I) will finish off a warship, because it did in WW2, are those with the legacy mindset these days.
I would love to see the brief for a crack at a Type 45 in the open ocean. Ugly scenes.
