Type 89 torpedo


The Type 89 torpedo is a Japanese submarine-launched homing torpedo produced by Mitsubishi Heavy Industries. It replaced the unguided Type 72 torpedo. Development was done by the Technical Research and Development Institute, a department of the Ministry of Defense, and began in 1970, with the design completed by 1984. Developed from the Type 80 torpedo, it is similar in its capabilities to the United States Mark 48 ADCAP torpedo. After being formally approved in 1989 and named "Type 89", it entered service and is currently carried aboard the Harushio, Oyashio, and Sōryū class submarines. It was also carried by the Yuushio class submarines before they were retired from active service in 2006.
It is a wire-guided torpedo that features both active and passive homing modes. Compared to Mk-48 torpedo, it is slightly longer and heavier, but has a smaller warhead. However, it can be used at a greater depth.
A succeeding design is in development under the development name of "G-RX6".
