The Tategami-class salvage tugboats (立神型救難船兼曳船, Tategami-gata Kyūnansen-ken-eisen) were 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

The IJN was going to build the 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.
