Recovery involved guiding the aircraft back to the deck and manually folding its wings for storage. However, the submarines were forced to abort their missions due to mechanical failures and the timely surrender of Japan in August 1945.
i-400 Class Engineering the Submarine Aircraft Carrier Concept
This ambition demanded a vessel with unprecedented range, capable of carrying enough fuel and aircraft to project power across entire oceans. Only three of the five completed vessels—*I-400*, *I-401*, and *I-402*—were operational by the time hostilities were drawing to a close.
This ability to conduct aerial reconnaissance and strike missions without requiring a traditional aircraft carrier provided the Japanese navy with incredible operational flexibility and strategic reach. Each submarine displaced over 6,500 tonnes when surfaced, making them the largest submarines in the world until the construction of ballistic missile submarines in the 1960s.
i-400 Class Engineering the Submarine Aircraft Launch Process
The process of launching an aircraft was a meticulously choreographed operation. The submarine would surface, partially flood its hangar to allow the plane to float clear, and then launch it using a catapult.
