Tsukushi-class survey ship
The was a class of auxiliary ships of the Imperial Japanese Navy (IJN), serving during World War II. The class consists of two subclasses, which this article handles collectively.
==Background==
Since the Meiji period, the Imperial Japanese Navy had carried out hydrographic survey with old naval vessels. While sufficient for routine peacetime survey duties, these obsolete vessels were deemed too slow for service in combat zones. Furthermore, these vessels were essentially fighting ships, thus were not able to carry many surveying devices. Therefore, in the 1920s and the 1930s, many of these ships were retired. The IJN then allotted ''Katsuriki'' and ''Komahashi'' to survey duties; however, these ships were of merchant ship designs, and were still too slow for the IJN. It then became clear that the IJN required purpose-built ships for hydrographic survey duties.
In 1930, the IJN proposed two 1,600-ton survey ships (Project Number J6) to the Ministry of Finance, but were unable to pass assessments. In 1937, IJN was finally able to get a building budget for one 1,400-ton survey ship. This is Project Number J11, later named ''Tsukushi''.
