The Tategami-class salvage tugboat (立神型救難船兼曳船,, Tategami-gata Kyūnansen-ken-eisen^?) was a class of rescue ship/tugboat of the Imperial Japanese Navy (IJN), serving during World War II. The class consists simplify production model the Miura-class (三浦型^?) variant, which this article handles collectively. The IJN official designation was 800-ton salvage tugboat (八〇〇瓲救難船兼曳船,, 800-ton Kyūnansen-ken-eisen^?) for all vessels.^[12]

Background[]

Under the Russo-Japanese War, the IJN purchased many steamships and converted them to salvage vessels. However, when they entered in 1930s, deterioration became remarkable. The IJN planned Tategami-class to update them.

Ships in classes[]

Tategami class[]

The IJN was going to build Tategami-class one by one for three years from fiscal year 1936, at first. However, the plan came to a deadlock for budget shortage by the second year. The IJN postponed building of second ship Oshima for two years.
