What Brassey's Naval Annual contributes to warship research

What is Brassey's Naval Annual, and what information does it contain?

It is a period naval reference with analytical articles, ship profiles, plans, and armor schemes useful for design research.

Brassey's Naval Annual combines naval reference material with articles on subjects such as battleships. The 1923 volume is named, and other editions are also brought into the demonstration. Ship profiles allow readers to compare appearances, while plans and armour schemes reveal aspects of internal arrangement and protection. Destroyer leaders and Japanese cruisers provide examples of the material available. Books of this kind supply period drawings for later explanations of warship design.
