Why a capital-ship article may omit HMS Hood

Why do accounts of 1920s and 1930s capital ships sometimes seem to overlook HMS Hood's size?

Omission is often a matter of relevance to the article's specific argument, not ignorance of Hood's status as a warship above 40,000 tons.

Historical writing cannot mention every relevant vessel in every article. An article about interwar capital ships can omit Hood, battlecruisers, or fast battleships when those types do not bear on the question at hand. The absence of a famous ship is therefore not proof that the historian forgot it. This moment is useful for reading naval history critically because it asks what an article is trying to explain before judging its selection of examples.
