• Chitose-class seaplane tenders come with a Zuiun as default equipment at their level 10 remodel.
• Chitose-class seaplane tenders come with two Type A Ko-hyoteki as default equipment at their level 12 remodel.
• Seaplane Tenders can equip depth charges to boost their ASW. They are, however, unable to attack submarines unless equipped with a seaplane bomber.
  • They can take down SS with the right equipment (such as Ka-type Observation Autogyro), however BBVs and CLVs usually get them first for 1-5 runs.
• Chitose-class seaplane tenders can be equipped with one or more Type A Ko-hyoteki midget subs to launch a preemptive torpedo strike. They can also do artillery spotting if equipped with main guns and seaplane.
• Chitose-class seaplane tenders can be remodeled into light aircraft carriers at level 15, losing all the specialties of seaplane tenders, but in turn, gaining all the specialties of light aircraft carriers. You can find the stats of their CVL class at this page to aid in your decision.
• Chitose and Chiyoda are the only ships (apart from Akitsu Maru) that can equip Daihatsu-class Landing Craft, an equipment that increases resources gained via expedition by 5% per equipped Landing Craft capped at 20% (4 equipped). This increase is multiplicative with great success results.
• Required for expedition 36 and quest A9.
  • Expedition 36 requires 2 AVs. As Expedition 36 is needed to unlock Expedition 37, 38, and 39, and as expedition 37 and 38 has a very high resources return per hour, it is advisable to keep them as AVs until you have cleared expedition 36.
• AV can be used for expeditions that require CV.
  • The running cost of unremodeled Chitose-class seaplane tender is equal to or lower than all CV and CVLs (except Houshou). This makes unremodeled Chitose and Chiyoda great members for expeditions requiring CV.
• Chitose and Chiyoda can also equip Drum Canisters.
