How would you design a battleship for both merchant raiding and battle-line service?
Short answerA fast battleship comes closest, but using one as a surface raider is wasteful; a cruiser is the more appropriate commerce-raiding tool.
NotesA commerce raider benefits from range, economy, and the ability to avoid superior forces, while a battle-line ship must carry the protection and heavy armament needed to stand in a fleet engagement. A fast battleship comes closest to meeting both requirements because it can move with the battle line and overtake slower targets. The panel nevertheless questions why such an expensive and conspicuous asset should be sent after merchant shipping. A cruiser offers the reach and economy needed for raiding without carrying battle-line capabilities that the mission does not require.
