Towada-class replenishment ship
The "Towada" class is a series of replenishment oilers of the Japan Maritime Self-Defense Force. Three ships of the class were built between 1985 and 1989. 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.
