Roles of support ships

  • Akitsu Maru is currently the only amphibious assault ship
    • LHA is one amphibious warfare type and the agreed stand-in as there is no equivalent.
      • Historically, Akitsu Maru was a landing craft carrier; in hopes of becoming an escort aircraft carrier, her remodel widened the flight deck increasing the ship's aircraft carrying capacity.
    • This role is reflected in Akitsu Maru being required for some installation type bosses.

  • Katori and Kashima are currently the only Training Cruisers (CT).
