The survey tested naval infrastructure against the Neptune class, then the Royal Navy's newest battleship type. Portsmouth and Devonport offered several options, while Gibraltar, Malta, Haulbowline, Hong Kong, and Rosyth provided selected overseas or regional berths. Some docks could accept a Neptune only when a movable caisson was placed at its outer stop, adding operational complication. Smaller cruisers fit many more facilities, revealing how rapidly support options narrowed as hull dimensions increased. Global deployability could be measured against the ship's dimensions and a list of specific usable docks.
