Fuyutsuki class destroyer

Yoizuki (宵月) was an destroyer of the Imperial Japanese Navy. Her name means "Moon Visible as Day Joins Evening". She was commissioned too late to see action in World War II. Following the war, the ship was handed over to the Republic of China and renamed Fen Yang.

The main armament of the Akizuki class consisted of eight 10 cm Type 98 dual purpose guns in four twin gun turrets, one superfiring pair fore and aft of the superstructure. Yoizuki was equipped with 41 Type 96 anti aircraft (AA) guns in seven triple gun mounts and twenty single mounts. The ships were also each armed with four torpedo tubes in a single quadruple rotating mount amidships for Type 93 (Long Lance) torpedoes; one reload was carried for each tube. The later batches of ships were each equipped with two depth charge throwers and two sets of rails for which 72 depth charges were carried. Yoizuki was equipped with a Type 13 early warning radar on her mainmast and a Type 22 surface search radar on her foremast.

In March, 1946, Yoizuki was used to transport over 1,000 Formosans, Filipinos and Japanese prisoners of war from Sydney, Australia. The conditions aboard ship and the obvious distress of the repatriates prompted controversy in Australia. On 29 August 1947, Yoizuki was turned over to the Republic of China. Renamed CNS Fen Yang, she was scrapped in 1963.
