What would happen if a Suffren-class cruiser encountered a Kongō-class battlecruiser?
Short answerAlone it would be lost, but French doctrine expected the cruiser to operate with a pack and supporting capital ship rather than fight Kongō by itself.
NotesA Suffren-class cruiser caught alone by a Kongō-class capital ship would be in grave danger. French doctrine did not intend that matchup to occur in isolation. The cruiser should be part of a pack that included several eight-inch ships and a fast battleship or British battlecruiser. The relevant comparison is force package against force package rather than cruiser against capital ship.
