"The two Tone-class cruisers (\u5229\u6839\u578B\u5DE1\u6D0B\u8266, Tone-gata jun'y\u014Dkan) were the last heavy cruisers completed for the Imperial Japanese Navy. The Tone-class cruisers were originally envisaged as the 5th and 6th vessels in the Mogami class. However, by the time construction began, serious weaknesses in the Mogami-class hull design had become clear following the Fourth Fleet Incident in 1935."@en . "189.1"^^ . . . "19.4"^^ . "64.82"^^ . .
