The C3s
were similar to the C1s, but had fewer torpedo tubes and sacrificed maximum speed for range. They were completed at the Kure Navy Yard in 1943. Another 17 units were
planned but not laid down. There were also plans for 25 units of an improved C4 class, but these were also never laid down.
Some authors list the C3s as C2s, the C2s as C1s, and the C1s as Cs.
