Would manpower limits prevent the Royal Navy from operating a much larger fleet of capital ships?
Short answerNot automatically. The Navy could recruit and pay more people, increase automation, or combine those measures, with continuous construction encouraging automated systems.
NotesCrewing requirements follow from ship design and sustained procurement policy. Automation reduces the number of sailors needed for weapons and machinery. Better pay and broader recruiting can expand the available workforce. An uninterrupted building programme would make automation more attractive because designers would confront crew requirements with every new class. Manpower is therefore a design and budget choice, rather than a fixed ceiling on fleet size.
