The original Cinque Ports still formed part of Britain's maritime system during this period, but their shipbuilding role was much smaller than it had once been. Larger southern centres had taken the lead in industrial construction and naval support. Southampton, Portsmouth, and Plymouth are named as the stronger examples. An older map of British maritime importance no longer described the industrial geography of steel warship construction.
