Type KD4


(Scanned from "Submarines of World War Two" by Erminio Bagnasco)

These boats were slightly smaller than the KD3 type and with only four forward tubes, but otherwise very similar.  I-162 and I-164 were originally numbered I-62 and I-64, respectively until renumbered in 1942.  I-61 was lost in a collision in October 1941, refloated, and scrapped.  I-162 survived the war, but I-164 was sunk by USS Triton (SS-201) in May 1942.
