Modifications | At some point, the units of this class were fitted with schnorkels |
The modified As
were based on
the I-12 (A2).
They were very large submarines capable of carrying two seaplanes
each. The boats also had an anechoic coating of synthetic rubber mixed
with sand with a thin plastic covering and were equipped with snorkels. The submarines were modified
specifically to reinforce the Sen-toku class submarines in
their strike against the Panama
Canal.
We list here only those units that were completed
before the surrender. Two additional units were laid down but not completed and three more units ordered but never laid down.
