| Modifications |
Late 1942: I-171 and I-174 were converted to transport submarines by removing the 4.7" gun and some torpedoes and adding a Daihatsu landing craft. |
The KD6As were
completed between 1934 and 1938 and were the first Japanese submarines
designed outside the limitations of the naval treaties.
Designated as large fleet submarines (Kaigun-dai), they had stonger pressure hulls and
better engines than earlier Japanese submarine classes. They also had
the highest surface speed of any submarines built to that time. They
were renumbered by adding 100 to the original number (so that I-68, for example, became I-168) in May 1942.
