Japanese destroyer Wakatsuki

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).[1] 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.[2]

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).[3]

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.[4]

Wakatsuki on fire and sinking, 11 November 1944

The ship was commissioned on 31 May 1943 into the 11th Destroyer Squadron. Wakatsuki participated in rescuing sailors from Shōkaku (June 1944) and Zuikaku (October 1944) when each was sunk by US forces. Both of these carriers participated in the attack on Pearl Harbor.

On 11 November 1944, Wakatsuki was escorting a troop convoy to Ormoc, Philippines. She was sunk by aircraft of Task Force 38 in Ormoc Bay, west of Leyte (10°50′N 124°35′E).

Wakatsuki's wreck was discovered in early December 2017 by Microsoft co-founder Paul Allen's research vessel RV Petrel 869 ft (265 m) below the surface of Ormoc Bay. She was found to be heavily damaged from both her sinking and impact with the seafloor, resting on her starboard side.[5]
