The classification argument reads Vanguard through the Royal Navy's contemporary design categories rather than assigning a later label from armor alone. Her designers distinguished fast-battleship projects from the fully armored battlecruiser lineage that produced Vanguard. That terminology matters because they were developing parallel projects with different subdivision standards. Contemporary battle-line designs had substantially more subdivision, even though Vanguard carried full armor by battlecruiser standards. Reading the design forward from wartime choices avoids forcing it into a later classification scheme. Vanguard's subdivision is described as about equal to or slightly better than treaty-era battleships, while the comparison with superior subdivision concerns her wartime contemporaries.

Reading Vanguard's design lineage forward
A classification aside argues that Vanguard should be understood through the Royal Navy's own wartime design categories, subdivision standards, and battlecruiser lineage.
