Re: Saving ships @GrumpyKiwi
We scrapped nearly all of the WWII battleships very soon after the war. All of the surviving QE class were knackered after bearing the brunt of the Mediterranean conflict, with Warspite, Valiant and Queen Elizabeth all seriously damaged at various times by mines and consequently not suitable for preservation.
The Revenge class were already in reserve at the close of WWII, because they were very slow and had fueling issues (they were built as oil/coal fired, and did not have the oil bunkerage for operations outside of the North Sea).
Nelson and Rodney were... odd. Very atypical, and would not really have been representative.
Keeping a King George V should have been possible, but it was again, these were paid off into reserve or used for training duties very quickly after the war.
Although it was not a WWII battleship, Vanguard, as the last operational British battleship (and probably the best looking example of British big-ship design - being closest to the canceled Lion class in design) would have been an excellent choice, but preservation efforts failed because it would have been so expensive (and the government in the '60s were desperately trying to cut the cost of defence).
But Belfast is not such a bad remnant. In terms of size, being the same length as the smaller British battleships, is reasonably representative of wartime cruiser design (being a stretched, or improved Southampton class), had been active in WWII and was in the best condition of all of the remaining available large ships. As such, she gives some impression of size and conditions for a large number of British ships.
