Secret Weapons of the IJA / IJN - Concepts, Projects and Operational Systems


While many sources cover the fantastic aircraft developments of the Germans in World War 2, Japanese engineers were hard at work on their own designs.

There are a total of 28 Secret Weapons of the IJA / IJN - Concepts, Projects and Operational Systems in the Military Factory. Entries are listed below in alphanumeric order (1-to-Z). Flag images indicative of country of origin and not necessarily the primary operator.


This listing attempts to include all manner of special Imperial Japanese Army / Imperial Japanese Navy aircraft projects related to the World War 2 period covering operational, conceptual, and development types. Designs that may have become available in 1946 are part of this showcase - should the war have been prolonged.
