As I mentioned earlier in this (or another) thread, I remain amazed at your willingness to forgive the 'big gun' admirals of any possible complicity in the lack of development of Brtish naval aviation.
Hindsight is a wonderful thing.
Back in the 1930's it would not have been unreasonable to believe that aircraft could not carry a weapon big enough to sink an armoured capital ship manouvering at sea.
The philosophy of aircraft being useful tools but not warship sinkers was realistically valid up until Taranto in late 1940, even then there was a legitimate view that it was only possible because the Italian ships were couped up in harbour and static targets
After Taranto Cunningham did say that the FAA had suddenly become an incredibly potent weapon.
A year later the Japanese had learned from Taranto and Pearl Harbour was the result for them.
Repulse and Prince of Wales were a significant loss too but again that was over a year after Taranto.
It wasn't until then that it was accepted and understood that capital ships manouvering at sea were vulnerable to air attack.
I would argue that it was Prince of Wales and Repulse that were the significant change rather than Pearl Harbour, Everybody knew that capital ships couped up in harour were vulnerable but there was a justifiable (if mistaken) belief that at sea they could hold their own against air attack at sea
In this thread we seem to continiously confuse timelines, who knew what and when, comparing aircraft available in 1939 to aircraft available in 1944 and also hard won knowledge that changed the way naval battle were fought over time. Nobody really knew in 1939 how naval warfare was going to change.
For all the talk on here about misjudgement and ineptitude, its easy to say 80 years after the fact!
Two snippets to consider-
The Fairey Fulmar was quite an effective naval aircraft at the start of the war, Fulmars shot down well over 100 enemy aircraft for about 40 losses.
The most succesful naval strike aircraft of all time? The Fairey Swordfish. Sank more shipping than any other aircraft. Ever.
