Yoizuki (宵月) was an Akizuki-class 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 destroyer. Her crew numbered 300 officers and enlisted men. The ships measured 134.2 meters (440 ft 3 in) overall, with a beam of 11.6 meters (38 ft 1 in) and a draft of 4.15 meters (13 ft 7 in). They displaced 2,744 metric tons (2,701 long tons) at standard load and 3,759 metric tons (3,700 long tons) at deep load.

The 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 52,000 indicated horsepower (39,000 kW) for a designed speed of 33 knots (61 km/h; 38 mph). The ship carried up to 1,097 long tons (1,115 t) of fuel oil which gave them a range of 8,300 nautical miles (15,400 km; 9,600 mi) at a speed of 18 knots (33 km/h; 21 mph).

The main armament of the Akizuki class consisted of eight Type 98 100-millimeter (3.9 in) dual purpose guns in four twin-gun turrets, two superfiring pairs fore and aft of the superstructure. They carried four Type 96 25-millimeter (1.0 in) anti-aircraft guns in two twin-gun mounts. The ships were also armed with four 610-millimeter (24.0 in) torpedo tubes in a single quadruple traversing mount; one reload was carried for each tube. Their anti-submarine weapons comprised six depth charge throwers for which 72 depth charges were carried.

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.
