How would Kongō fare in a one-on-one fight with Renown or Repulse?
Short answerRenown is favored through superior radar and fire control. Kongō is favored over Repulse by day, while both British ships are favored at night because of their night-fighting training.
NotesRenown is favored because her radar, fire control, and guns should produce effective hits sooner. Kongō is expected to defeat Repulse in daylight, while British training and practice in night fighting favor both Renown and Repulse after dark. All three are lightly enough protected relative to their weapons that early effective hits would matter greatly. These are conditional judgments about fire control, armament and training, with different outcomes expected by day and by night.
