Capital ships underserved in English-language history

Which capital ships have been overlooked in naval history?

The Littorio, Dunkerque, and Gangut classes are suggested as deserving more English-language attention.

The Littorio class is judged underserved in English-language naval history. The Dunkerques receive a similar mention, though some French cruisers had too little service time to develop the careers their designs promised. That limited opportunity is a different issue from neglect of ships that were actively used. The Ganguts belong to the latter category: their continued Soviet employment is offered as a reason to study their work more closely. Another First World War class is mentioned unclearly, so it cannot be identified confidently from this passage.
