Force Z would suggest his 'experiment' was actually pretty accurate.
On the face of it perhaps, but in reality no.
Had PoW and Repulse been faced with a Billy Mitchell type attack then they wouldn't have been sunk.
It was torpedo bombers that did for them in massed attacks
Time and technology had moved on by 1941.
Prince of Wales in particular was well equiped to counter air attack, trouble was whe was built for a different fight and crucially a different climate. Fire control radars and AA amunition failed to operate properly in the heat/humidity and nobody anticipated torpedo bomber attack on the scale they got.
Had a carrier been with it Force Z it might have been different, had the state of the art fire control radars been working it might have been different, had all the AA amunition worked it might have been different. Even if the RAF's Brewsters been there an hour earlier it might have been different
That's war I suppose, sometimes the other side wins.
