Japanese destroyer Yoizuki

Yoizuki (宵月) was an Akizuki-class destroyer (1942) 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.

Design and description
The Akizuki-class ships were originally designed as anti-aircraft escorts for carrier battle groups, but were modified with torpedo tubes and depth charges to meet the need for more general-purpose destroyers. The ships measured 134.2 m overall, with beams of 11.6 m and drafts of 4.15 m. They displaced 2744 t at standard load and 3470 t at deep load. Their crews numbered 300 officers and enlisted men.

Each ship had two Kampon geared steam turbines, each driving one propeller shaft using steam provided by three Kampon water-tube boilers. The turbines were rated at a total of 52000 shp for a designed speed of 33 kn. The ships carried enough fuel oil to give them ranges of 8300 nmi at speeds of 18 kn.

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 25 mm anti-aircraft (AA) guns in seven triple-gun mounts and twenty single mounts. The ships were also each armed with four 610 mm 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.

Construction and career
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.
