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

Construction

Hayasui was completed as one of the Kazahaya class fleet oilers. After lack of reconnaissance planes was identified as a contributing factor to defeat of the IJN at the Battle of Midway, aviation facilities were added to Hayasui for accompanying the carrier task force. The IJN added the function of food supply ship to Hayasui to improve carrier task force endurance following experience at the Battle of the Santa Cruz Islands.
