The Tase-1, also known as Mark 235 or "Ultrashortwave Warning Device B", was built by the Japanese
Army for use on its own fleet of transport
ships and submarines. Its
existence illustrates the duplication of effort engendered by the
severe interservice rivalry in Japan. The radar was unsuccessful, in part because of a mistaken belief by the Army that Allied aircraft could home on its transmissions, and the Army reluctantly adopted the Navy Type 22.
