The Towada-class is a series of replenishment oilers of the Japan Maritime Self-Defense Force (JMSDF). Three ships of the class were built between 1985-89. The ships have the hull designator AOE.
The Towada-class was designed as an enlarged, improved version of the Sagami-class fast combat support ships. The vessels are capable of mounting the Phalanx CIWS by design, although this is not a common occurrence.
