In the Naval Battle of Guadalcanal, a lookout for Ayanami, entering the southern channel of Savo Island, spotted a single column of American ships about 8,000 yards to the right of the bow. Meanwhile, Kawanai, who was engaged in battle with the American fleet and belonged to the main task force, reported to the entire Japanese fleet that he had spotted an enemy fleet fleeing, but Ayanami could not receive the report, and it was likely that the radio waves would be blocked by the Savo Island. At this point, Captain Ayanami gave the order of "right artillery battle, right torpedo battle" , increased the speed to 30 knots after reporting to the home team that "the enemy was four destroyers and one heavy cruiser" had mistaken the battleship for a heavy cruiser. Unfortunately, the home team of the sweep at this time, "Kawanai" and 2 destroyers because of the adverse situation temporarily back. This became "Ayanami" single ship to face the U. S. Two battleships, four destroyers situation. Ayanami's success in this battle was to sink two destroyers and seriously injure one, it also caused the power supply of the "South Dakota" to be cut off. At that time, the Japanese side mistook the "South Dakota" as a heavy cruiser, and judged that the "heavy patrol" was sunk because the "heavy patrol" was stopped from carrying out the "heavy patrol" . But this is actually an unsubstantiated objection and the gun that makes it impossible to fire is actually a dual-purpose gun of the South Dakota, and was himself eventually sunk. During the Naval Battle of Guadalcanal, the entire 2nd fleet sank and wounded four enemy ships, half of which were made by Ayanami. Therefore, the term "Black Panther" and "ghost God" was obtained in the Japanese army.
