The A1s were based on the J3s and were fitted to serve as flagships. They were among the most modern submarines in the Imperial Navy, incorporating all the lessons of prewar submarine design and operation.
These boats had a pressure cylinder to the front
of their conning tower that could hold a single seaplane. Just forward
of this hangar was a bow catapult for launching the seaplane.
Two additional units were planned but were
cancelled in 1942.
