Why Britain preserved no pre-dreadnought battleship

Why did Britain not preserve at least one pre-dreadnought as a museum ship?

Because preservation was not seriously considered; the navy prioritised clearing old ships and looking toward the future.

British decision-makers did not seriously plan to preserve a pre-dreadnought. They repeatedly presented scrapping as part of a forward-looking naval culture, even when that meant losing representative historic ships. The result is a major gap between preserved sailing warships and later twentieth-century museum ships. This explains why Britain's physical record of the pre-dreadnought transition is so thin.
