===Map Unlocking & Progression===
'''7-4''' is unlocked after clearing [[7-3]] HP bar once.
=== Stage Guide ===
To clear the map, the boss's flagship must be sunk 4 times.
*1 [[LBAS]] is available on this map.
**The LBAS is only available once {{Q|B175}} is cleared.
**See the unlocking steps here: ''[[Land-Based_Air_Squadron#Unlocking|LBAS Unlocking]].

{{color|orange|'''Be advised:''' The Developers have mentioned that the composition and map will change over time, this may even include the resource node possibly. So take advantage of the map while it is possible.}}
====Regarding [[Land-Based Air Squadron]]s====
===Regarding [[Land-Based Air Squadron]]s===
*1 [[LBAS]] is available to sortie.
*You are permitted to use 1 [[LBAS]].
**It is '''highly recommended''' to use the LBAS to help simplify the battle on the boss node for this map.
*Upon completing the quest [[Quests#B175|B175]], you will gain access to an LBAS, which is '''highly recommended''' to help simplify the battle on the boss node for this map.
**It is recommended to bring [[Land-Based Attacker]]s, {{Equipment/Link|Prototype Toukai|Toukai (901 Air Group)|text=land-based ASW bombers|link_category=Land-Based ASW Bombers}}, and [[Interceptor|fighters]], to increase effectiveness on the Boss.
*It's recommended to bring Land-Based Bombers, Fighters, and ASW planes in it if you want to increase your effectiveness on the Boss.
**The LBAS range needed to reach the boss is '''2''', other nodes' range being equal or higher.
*The LBAS range needed to reach the boss is '''2''', and the other nodes range is equal or higher.
*This map is also the best location to train all land-based planes to [[Proficiency|max-proficiency]]{{Double Chevron}}. Bring only planes with a range of at least 3 (7 for furthest nodes) as they will reach submarine Nodes on B, C, J, and K.
*This map can also serve as a good location to train your Land-Based attack planes to max expertise. Bring only Land-Based Attackers with a distance of 3 or 7 (or more) as they will reach enough distance to reach submarine Nodes on B, C, J, and K, where your planes should target in order to be trained.
===Recommended Fleets===
===Recommended Fleets===
This guide will go over the events of this map from the sequential order when you obtain Quest B175. Since this a normal map, you do not necessarily have complete things in the order mentioned, but to make things most convenient for you, it's recommended to at least complete B175 to access the LBAS.
This guide will go over the events of this map in the recommended sequential order upon unlocking quest {{Q|B175}}.
==== Traveling to Kaohsuing (For Quest B175)====
====Reach Node O====
* Composition: 1-6 SS(V)
Quest {{Q|B175}} requires to reach node {{MapRoute|O|green}}:
* 1-6SS(V)
* Route = {{MapRoute|C|red|D|pink|F|blue|J|red|K|red|M|pink|O|green}}
* Route = {{MapRoute|C|red|D|pink|F|blue|J|red|K|red|M|pink|O|green}}
* The LOS Range needed is estimated to be 30 Cn3
** The LoS needed is about 32 (Cn3).
* Submarines will face little to no threats along the way. At most they will take 2 loses and 3 wins.
** Several {{Seaplane}} [[Seaplane]]s or {{SubmarineRadar}} [[Submarine Radar]]s might be needed to have enough LoS to route from {{MapRoute|M|pink}} to {{MapRoute|O|green}}.
* Using [[List of Seaplanes by stats|Seaplanes]] or {{EquipmentLink|Submarine Radar & Waterproof Telescope|Submarine Radar & Passive Radiolocator (E27)|Late Model Submarine Radar & Passive Radiolocator|text=Submarine Radars}} to have enough LOS and so route from {{MapRoute|M|pink}} to {{MapRoute|O|green}}.
** Submarines will face little to no threat along the way.
* Once your submarine fleet reaches {{MapRoute|O|green}} you will gain {{Fuel}} and {{Bauxite}}
====Sink the Hi Convoy Princess====
====Sink the Hi Convoy Princess {{MapRoute|P|red}}====
In this part, it is recommended to use the LBAS to clear the map more easily, as this will give the necessary edge needed to fight against the boss. While the boss is not strong, she is very tanky and is escorted by a fleet that may be troublesome to wipe.
<tabber>
|-|Heavy fleet =
*0-1BBV, 1CVL, 1CA/CL, 3-4DD/DE
*Route = {{MapRoute|A|blue|B|red|E|pink|J|red|L|red|P|red}}
*LBAS Node {{MapRoute|P|red}}: Range = 2
** Allows bringing a strong fleet to the boss.
** Fleet will go through 2 Submarine Nodes, 1 Air Node, and 2 Surface/Submarine Nodes.
** Node {{MapRoute|J|red}} can especially be problematic due to it featuring 3 {{Enemy/Link|Submarine So-Class Flagship}}, but will become even more dangerous on Last Dance with the enemy fleet in ''line ahead'' formation.
* It is recommended to bring:
** Ships that can effectively [[OASW]] to survive the submarines.
** An {{Ship/Link|Ise Kai Ni|Hyuuga Kai Ni|text=''Ise''-class Kai Ni}} and a [[CVE]] to help clearing while having AS.
** An [[AACI]] for node {{MapRoute|E|pink}} as well as the boss.
** At least 1 TCI capable DD.
** If possible, ships that can take on multiple roles.
*Composition :
* The boss does not have a lot of planes, bringing enough airpower and AACI can effectively deplane her, rendering her defenseless.
*{{MapRoute|A|blue|B|red|E|pink|J|red|P|red}}
* LBAS should use a combination of Fighter, Bombers, and ASW Bombers to effectively help with clearing the boss.
* Last Dance comp will buff the DDs and CL in her fleet along with giving her additional airpower.
** Bring additional airpower as a countermeasure to effectively beat her.
|-|Torpedo Squadron fleet=
{{color|red|'''"Torpedo Squadron"'''}}: '''1CL (flagship), 4DD, 1CLT'''
*Route = {{MapRoute|C|red|E|pink|J|red|L|red|P|red}}
*LBAS Node {{MapRoute|P|red}}: Range = 2
**This solution requires more advanced gears, and might be out of reach of new players. {{color|red|'''It is required to bring'''}} an {{CommandFacility}} FCF capable CL as flagship, preferably an {{Class|Agano|Kai+}}, equipped with:
***2 {{Med Gun}} [[Main Gun]]s,
***1 {{Night SPB}} {{EquipmentLink|Prototype Night Zuiun (Attack Equipment)}},
***'''And''' the {{IconText|{{CommandFacility}}|ETSCF}} {{EquipmentLink|Elite Torpedo Squadron Command Facility}} (preferably in the [[RE]]).
**It also requires '''at least 5 OASW along with married DDs''' to allow them to do TCI while enabling their OASW with sonar alone.
**If you meet all of the above requirements, this is the cheapest (for resource) and the best comp for farming boss node, having the highest pass rate thanks to the usage of [[ETSCF]] in case a ship got heavily damaged.
**The [[Evacuation]] mechanic of the ETSCF should be used if needed, as long as the routing is maintained.
***C - E route is secured if you '''have 4 DDs in the fleet'''.
***The boss routing is secured as long as '''the fleet LoS is above 37 Cn4'''.
**Do note that the [[Night Zuiun]] will likely be shot down completely due to fighting under AI and the presence of {{Enemy/Link|Light Cruiser Tsu-Class|text=CL Tsu-Class}}.
|-|Light fleet=
*Composition :
This fleet is not recommended as it is very weak and will struggle to kill the boss, but can be enough if only an A rank is required.
*{{MapRoute|C|red|E|pink|J|red|L|red|P|red}}
*1CT, 1DD / 1 {{Ship/Link|Taiyou Kai Ni|Shinyou Kai Ni|Unyou Kai Ni|text=Taiyou-class CVE}}, 3DE
*Route = {{MapRoute|A|blue|B|red|E|pink|J|red|P|red}}
*LBAS Node {{MapRoute|P|red}}: Range = 2
**This map has a special routing for {{Ship/Link|Taiyou Kai Ni|Shinyou Kai Ni|Unyou Kai Ni|text=''Taiyou''-class CVE}}, who can be brought when using light fleet to get more firepower. It is a cheap but weak fleet.
** Will go through, 1 Submarine Node, 1 Air Node, and 1 Surface/Submarine Node.
** Not recommended due to the risks this map presents to fleets with a lack of strong combat-effective ships.
** Dependent on the DD or CVE to score the kill against the boss.
** DEs will take on OASW.
** The CT will mainly do Surface Combat.
** The DD will do a TCI, CVE should do night carrier cut in attack.
** Node {{MapRoute|E|pink}} and {{MapRoute|P|red}} may be troublesome due to a lack of air defense.
** LBAS should focus on removing the surface ships to make scoring the kill against the Boss more likely.
** The DD or CVE needs to avoid taking too much damage to effectively kill the boss.
|-|Formation Guide=
See: ''[[Combat#Formation_Selection|Formations]]''.
It is advised to use ''Line Abreast'' on most of the map:
* Nodes {{MapRoute|B|red|C|red|G|red|J|red|K|red|L|red}}
*{{MapRoute|C|red|E|pink|G|red|P|red}}
''Diamond'' is advised on:
* Nodes {{MapRoute|E|pink|M|pink}}
For Boss {{MapRoute|P|red}}:
* Depending on how the LBAS is setuped:
** '''Line ahead''' is recommended if the LBAS can effectively kill the enemy SS.
** '''Echelon''' or '''Double Line''' is preferred if the LBAS is not set to fight SS.

===Resources and LBAS Farming===
{{color|red|Doing this farming will bring a lot of "losses", which can impact overall win rate and thus "event eligibility".}}

* Route = {{MapRoute|C|red|D|pink|F|blue|J|red|K|red|M|pink|O|green}}
* LoS required: '''≥ 32 F33 Cn3'''
** LoS required: '''≥ 32''' (Cn3)
* A maximum of {{Amphibious Tank}} [[Amphibious Vehicle]]s should be used as they provide the best earnings for submarines.
** {{Drum}} [[Drum Canister]]-capable SS are recommended as a substitute, increasing the resource gains without requiring more Amphibious Vehicles.
** The {{Bauxite}} gain cap being relatively low, it will be capped by using only 10 {{Amphibious Tank}} or 4 {{Drum}} + 8 {{Amphibious Tank}}.
** It is not possible to reach the {{Fuel}} gain cap with a submarine only fleet.
*To meet the LoS requirement, using {{Seaplane}} [[Seaplane]]s and/or {{SubmarineRadar}} [[Submarine Radar]]s may be required.
**If possible, it can be advisable to use [[RE]], as {{SubmarineRadar}} [[Submarine Radar]]s can fit in them.
* While this map has little to no threat against a full submarine fleet, {{MapRoute|J|Red}} will have rare instances where destroyers may pop up in the composition that will damage the SS. Please be aware of this while farming this map.
** '''Do not consider farming during Boss Last Dance''', as {{MapRoute|J|Red}} will be locked on this 2 Destroyer composition.
|-|LBAS farm=
It is possible to farm for LBAS [[Plane Proficiency]] {{Double Chevron}} by sending the LBAS on a submarine node like {{MapRoute|J|red}} or {{MapRoute|K|red}}.
* Just set-up an LBAS with any planes, according the final range is enough to reach {{MapRoute|J|red}} or {{MapRoute|K|red}} (3 range each).
** Sending a surface-focused LBAS on {{MapRoute|J|Red}} can assure a safer path. Such runs consume little to no resources on the LBAS.
