The K6s were
short-ranged (RO) submarines based on the K5
prototype class. However, they had stronger hulls, superior machinery,
and greater fuel capacity for better range. They were also the first
short-ranged submarines equipped to fire Type 95 torpedoes.
They were excellent boats with good maneuverability, but construction
of RO submarines was ended in 1943 due to heavy combat losses.
