World 6/6-4

Strategy

 * Can use a maximum of 1 Land Base Aerial Support squadron. No abyssal air raid.
 * You need at least 5 range to reach the boss with your Land Base Aerial Support.
 * Requires sinking the flagship at the Boss node 5 TIMES to deplete the gauge and clear the map.
 * Maximum 2 BB and/or 2 CV/CVL allowed to sortie.
 * The boss node has 3-5 land based targets, Isolated Island Princess and Supply Depot Princess, accompanied by 2-3 Artillery Imps.
 * On the last kill boss and pre-boss nodes switches to stronger patterns as noted with ( F in the table below).

Compositions

 * West Start: B-D-C-F-N: 1 CL (flagship) + 1 FBB (or 1 CA(V)) + 3 DD + 1 CAV (video) (5 Battles Total including Boss) or A-D-C-F-N: Akitsushima + 1 CA/CL + 2 DD + 1 CAV + 1 BB(V) (5 Battles Total including Boss)
 * Node D and F are Air Raid Battle nodes.
 * Node B and C are normal battle nodes.
 * East Start: M-K-J-I-N: 2 CV CA CL 2 DD / 1 CV 1 BB 1 CL 1 CA 2 DD
 * Node I is an air defense node and doesn't eat much resources as cost.
 * To skip I (and go J-N) replace a CV with Akitsumaru Kai.

Node M Land-Based Aircraft Proficiency Leveling

 * If you wish to rank up your Aircrafts' Aircraft Proficiency, you may utilize node M to do so.
 * Your Land-Base' Range must be 8 or higher (Range is counted from the West starting point even if you started from the East)
 * If you are trying to rank up Aircraft with lower range, you may be required to bring a Type 2 Large Flying Boat (3+ Range) or PBY-5A Catalina (2+ Range) to increase your Land-base's range.
 * Due to the maximum range increase being 3+, you will be unable to use this method to rank up any aircrafts with 4 or lower range even if you bring a Large Flying Boat or PBY-51 Catalina.
 * Sortie 1 Submarine with a variety of Aircrafts to rank up in your Land-Base. You will start from East.
 * Send your Land-Base Aircraft Support to attack node M only twice.
 * This will result in a Rank D loss, but your Aircrafts will be ranked up from Blank to Double Chevron after around 12 runs.
 * You may ignore morale on both your submarine and Aircrafts all the way.
 * 1 or 2 Aircrafts may be shot down sometimes which will only cost around 3 fuel to 5 bauxite per plane.
