Type 98 Ta-Se
The experimental Type 98 Ta-Se was a Japanese self-propelled anti-aircraft gun using a Type 98 20 mm anti-aircraft gun. It used the chassis of the Type 98 Ke-Ni light tank. It did not enter production.
History and development
During development of an AA gun tank, the Imperial Japanese Army experimented with various configurations. Prior to the Type 98 Ta-Se, an earlier prototype was produced that was known as the experimental Type 97 Ki-To self-propelled anti-aircraft gun. The original Type 97 Te-Ke tankette turret was removed, and a single Type 98 20 mm AA machine cannon was mounted on the modified chassis without a protective gun shield. It did not enter production.Thereafter in November 1941, initial development began on a new prototype single gun AA tank that was designated the Type 98 Ta-Se self-propelled anti-aircraft gun. The name was taken from taikū ''sensha''. The conventional turret was removed from the hull and a new open-top cylindrical shaped turret was installed. It was equipped with a single converted Type 98 20 mm AA machine cannon. During trials, it was determined that the chassis used for the Ta-Se was too small to be a stable "firing platform". It did not enter production.
