Dock size as a constraint on ship design

The video uses repeated British dock expansion to show that infrastructure places a hard ceiling on warship dimensions. Private yards often enlarged their own facilities while competing for government contracts, but a ship still had to fit the docks that would build and maintain it. The length of the modern Queen Elizabeth class carriers is linked to the dry-dock space available for their construction. Had Britain maintained more docks forty or fifty metres longer, it could have considered different hull proportions. Chatham provides the opposite lesson: facilities well suited to nineteenth-century ships lost strategic value as later warships outgrew them. A later exchange notes that authorization for the Montana-class battleships included money to widen Panama Canal locks and also required attention to dockyard capacity, showing the same constraint in an American case.
