On board the I-21, Kadomatsu tries to get a warning to the Mirai via Morse code but is stopped by Taki. At first, Mirai attempts to leave the scene, rather than stand and fight, but Taki forces the issue by ordering the I-21 to surface so that it would be left vulnerable to an air attack. Rather than leave I-21 to be attacked by the Americans, Captain Umezu decides to stay around and face the attack. Oguri thinks they should engage the Americans afar, taking advantage of their technological advantage, but Kikuchi argues that they should wait until the range closes, since the supply of the long range Standard missiles is limited. In fact, Kikuchi thinks he can spare lives by demonstrating Mirai's firepower to destroy only a fraction of the American strike force, so that the rest would be frightened away. The strike force from the USS Wasp finds the destroyer. Using its advanced weapons, the Mirai shoots down two-thirds of the American aircraft in less than a minute.
