The KTs (Kai-toku-chu) were
short-ranged (Ro) submarines
completed
between 1923 and 1924 at the Kawasaki
shipyard in Kobe.
They were based on the French Schneider-Labeuf
design. The boats originally had five torpedo tubes, but one was subsequently removed.
They were of limited usefulness, particularly since they could only fire obsolete 18" torpedoes,
and they had already been relegated largely to training duty by the start of
the
war. However, their design was the basis for subsequent classes that made up Japan's coastal submarine force during the war.
