After some time absent from drawing warships here is the IJN submarine I-6. These seagoing submarines had their catapult aft of the conning tower, the hangar was two cylinders on deck into which the aircraft was placed. That was a lengthy process, and dismantling the aircraft so it would fit the hangar took a lot of time.
