    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 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.
