Why might Australia build its County-class cruisers locally instead of buying from a large British production run?
Short answerLocal construction costs more, but it creates Australian industrial and support capacity useful for Far Eastern operations.
NotesIf Britain were constructing forty County-class cruisers, its yards would gain powerful economies of scale. An Australian-built ship could cost much more because local infrastructure first had to be created. Subsidizing that premium could still make strategic sense because the new yards and support facilities would strengthen Far Eastern deployments. The choice is between immediate production efficiency and long-term geographic resilience.
