For heavy AA 5" is better than 3". The 5"54 did have some advantages over the 5"38 but didn't have the rate of fire and due to the extra weight couldn't maintain what it did have for as long. Either would probably be a good choice and better than the 3". 6" was a bit too much for effective AA use so going that way precludes having a dual purpose gun that worked well in both catagories.

I would have thought therefore that radar and an open sea would allow a six inch gun to be deployed against formations of aircraft at long range? - but that there was no conflict at which that idea could be tested?

It might have been, but despite what some people say I believe that it was the torpedoes from the Dorsetshire that finally sank her.

The ship is large enough and fast enough to defeat any known or hypothetical opponent (1940-46), with armored protection on a Montana scale or better (16-18inch belt, 20 inch turret faces, 18inch CT and 8inch decks). A better sea boat than Iowa, she can sail the Atlantic without shipping green water over the bow and have super speed to any known Axis battleship.
Seekanone wrote:40mm guns were too light to engage Kamikaze's and 5inch became so by the end of the war. Proximity fuzes were what made the 5inch so effective. Twin 3/50s were substituted for all quad 40mm mounts at wars end, witness the armament of the Worcester and Des Moines class cruisers. The Iowas only retained their 40mm quads because they had spend time in the reserve fleet and were badly needed on the gunline off of Korea.
Had the Montana or BB65-8 been completed, 5inch/54 might have been used but the 40mm would have been out
and 3/50 mounted in their place.
