My understanding from various sources was that the main guns were 'not' going to be modified to full MK1N standard in respects to swapping the Power and Shell Magazines - as this was too time consuming and the large gun facilities in Britain IIRC amounted to 9 large gun pits which at the time were in use building the remaining turrets for the KGVs.
My understanding is that the turrets would be improved to some degree, secondaries updated (Im guessing twin 4.5s along the lines of Renown or even 5.25s?), torpedo tubes removed, machinary updated or possibly given teh time contraints simply refurnished in which case her fresh water condensers would very likely to have been completely overhauled) and her deck armour doubled (providing weight savings could be made) and her superstructure fully or maybe partially revised (in line with other RN BBs) - i doubt that aircraft handling and hangers would be added.
I cannot recall if she would have received an improved torpedo bulge or not? But i suspect she would have done in line with Renown.
Interesting..
4.5s are far more likely, considering the high demand for the 5.25.
Would they really have time to revise the Superstructure? Maybe strip the armour from the conning tower, as it was rarely used
aircraft facilities-unlikely, the admiralty was already reconsidering this for BBs
Maybe new fire control? I think there was a spare Admiralty fc that they were planning for one of the Rs
i wonder how much the torp tubes weighed..
