Modifications Fitted for midget submarines for the Pearl Harbor attack

The C1s or Hei-gata were based on the K6As and were similar to the A and B series except for the absence of a float plane. All were deployed off Pearl Harbor to launch midget submarines on the morning of the fateful attack. The C1s later served as mother ships off Diego Suarez (Madagascar), Sydney, and Guadalcanal.
