What would happen if R-class battleships were rebuilt as faster ships with three triple 15-inch turrets?
Short answerThey would become dangerous fast battlecruisers for commerce warfare, but their limited armor would make maneuver and avoiding entrapment essential.
NotesThe hypothetical reconstruction replaces an R-class ship's old arrangement with three triple 15-inch turrets and much more machinery. Such a ship would accelerate the British battle line and create a fast force able to overwhelm detached enemy units. It would still be a battlecruiser because the conversion would not give it the armour needed to fight its way out after being pinned. Its value would lie in mobile commerce warfare and forcing an opponent to keep the fleet concentrated, rather than standing in a line-of-battle slugging match.
