A brief aside asks what a battleship built around the HARP gun might look like. The weapon is described as two 16-inch/50 barrels welded together. That extreme length would make fitting it into a practical ship arrangement difficult before turret and ammunition requirements were considered. The reference remains a thought experiment within the game design rather than a historical battleship proposal.

A brief aside uses the HARP gun's joined 16-inch/50 barrels to show why extreme barrel length would complicate a battleship installation.
