The Sendai-class cruisers (川内型軽巡洋艦) were a development of the preceding Nagara class. Their boilers were better located, and they had four funnels instead of three. Each ship was designed with a flying-off platform and hangar, but did not actually carry aircraft (seaplanes) until a catapult system was installed in 1929. | The Sendai-class cruisers (川内型軽巡洋艦) were a development of the preceding Nagara class.
