Hibiki (響, "Echo") was the twenty-second of twenty-four Fubuki-class destroyers, or the second of the Akatsuki class (if that sub-class is regarded independently), built for the Imperial Japanese Navy in the inter-war period. When introduced into service, these ships were the most powerful destroyers in the world. They remained formidable ships well into the Pacific War. Hibiki was among the few destroyers to survive the war. In 1947; two years after she was struck from the Japanese navy list, Hibiki was transferred to the Soviet Navy as a war reparation, and was later sunk as a target practice sometime in the 1970s.
