Hayasui (速吸, "Quick Absorption") was a Japanese fleet oiler with aircraft facilities (hybrid tanker/carrier) of the Imperial Japanese Navy (IJN), serving during World War II.

Construction

Hayasui was completed as an "improved Kazahaya-class fleet oiler", being therefore the only one of her class. After the lack of reconnaissance planes was identified as a contributing factor to the defeat of the IJN at the Battle of Midway plus the loss of four carriers, aviation facilities were added to Hayasui for accompanying the carrier task force, were six planes could be store on the deck with an additional plane on the launch catapult. Those aircraft could be either Aichi E13A reconnaissance seaplanes, or Aichi B7A Ryūsei torpedo bombers, with the latter unable to land back on her and therefore had to land elsewhere.[1] The Navy later added food supply facilities to the ship to improve the carrier task force's endurance following experience at the Battle of the Santa Cruz Islands.

Service

The ship was completed on 24 April 1944. In May Hayasui sailed to Tawi-Tawi for Operation A. On 5 May the ship collided with the submerged submarine I-155.[2][3] From 19 to 20 June 1944 Hayasui participated in the Battle of the Philippine Sea and was damaged. On 10 August, repairs were completed for convoy Hi-71 departure from Moji to Singapore.

At 03:20 on 19 August Hayasui was torpedoed twice by USS Bluefish west of Vigan City. At about 05:00 the ship suffered an explosion and sank at 17°34′N 119°24′E / 17.567°N 119.400°E / 17.567; 119.400. On 10 October the ship was struck from the navy list
