American submarine yards were already committed to US orders, while Britain's constraint was trained personnel more than physical space. Fleet-size announcements therefore could not substitute for yard capacity and workforce planning. One plausible path would build early Australian boats in Britain with Australian workers embedded in the programme, then transfer skills and later construction to Australia. The same relationship between industrial capacity and fleet plans applies to modern submarine procurement.

Fleet targets fail without shipyard capacity
Plans for larger fleets or Australian nuclear submarines must begin with the yards and skilled people available to build them.
