Statement in opposition of the planned construction of the Yamato class battleships, as quoted in Scraps of paper: the disarmament treaties between the world wars (1989) by Harlow A. Hyde. In this statement, Yamamoto implies that even the most powerful battleships can be sunk by a huge swarm of carrier planes. This remark also proved prophetic as both Yamato and Musashi would be sunk by overwhelming air attacks.
