Without detracting from your point, there is a massive cultural difference between the USA and UK re. Museum ships generally. UK does not hang on to that many old ships, USA tries to preserve all it can, maybe too much so?The Essexes and their GATO/BALAO submarine contemporaries, have examples which are now museum ships with the pedigrees of the Constitution. Even the North Carolinas and the Iowas are so honored.
Where is the Illustrious and T class sub?
Also desperate postwar economics forced a quick sale of much of the wartime royal navy. Literally the proceeds from scrapping sales being needed to pay to keep the government going. Which is why there is no HMS Warspite floating museum. The largest survivor from that period being the 6 inch gunned HMS Belfast.
