Map Guide

Notes

• (f)BB(V) and CV(B) cannot be sortied to this map; CVL is allowed
• You are given 3 Land-base, but only 2 can be sent out; last one is for defending only.

Rather than being hard, this map is just tedious, especially the TP Phase. You will need at least:

• 2 CVL - [Fast/Slow varies, See below in Phase 1]
• 1 CL - Preferably Jintsuu
• 5 DD - Preferably Historical ones and/or daihatsu carriers for TP Phase.
• 1 CAV/AV - Fast preferred, or turbine/boiler needed.
• Auxiliaries
  • 0 or 2 SS(V) [See Phase 1]
  • 0-1 AO [See Phase 1]

Don't forget about formations!

• Line ahead, or Bottom-right formation in combined fleet - for damages
• Line abreast, or Top-left formation in combined fleet - sinking submarines
• Vanguard formation for single fleet - survivability
  • If you use Shelling Node Support, Vanguard is not recommended, as your support is affected by the formation (Vanguard's lower shelling modifier is 50%) that applies to the whole fleet, not just the bottom-half. In other words, your support will only do 50% of its intended damage.
    • If you bring Shelling Node Support, use Line Ahead.

Medium+ Only: High-altitude Air Raid: LBAS Defense Check for Boss Unlock

For Medium+ ONLY. Similar to E-3 and E-4. If you can pass E-4 then this one is a lot lower: LBAS Air Defense Values

• For 0.5x: (for 0 high-altitude interceptor)
  • Hard: 390+
  • Medium: 246+
• For 0.65x: (for 3 bases with at least one Saiun in each)
  • Hard: 300+
  • Medium: 190+

Phase 1: Opening Boss Node Y

Do the following in any order (Be advised some below may not be required for lower difficulties)

Unlock Requirements
Difficulty	P	F	Q	V	W	LB Defense
Hard	-	S	S	S	S	AS x2
Medium	-	S	S	S	S	AS
Easy	-	-	S	S	S	-
Casual	S	A	S	-	-	-

LBAS

• If you still have the 0-1 Saiun 1-2 Fighter 2-3 Bombers setup on both of your bases from E-4, you can keep it as such for now. Node P and W have air power. Keep your 3rd Base in Defense because you still need to obtain two LBAS defense too. If you cannot achieve AS with 1 Base (see above), you will have to switch around your LBAS later.

Nodes P and V: D E H J P R V

• CTF - 2 CVL 1 CL 2 SS(V) 1 XX + 1 CL 3 DD 2 XX [Slow allowed]
  • XX must not be DD, or you will go to T from P
  • 2 SS(V) can be replaced with AO.
• CTF - 2 CVL 2 CA 2 CL + 2 CA(V) 1 CL 3 DD [Fast Required]
  • As long as the amount of CA(V)+CL+CT ≥ 6. However, 7 or more can cause random off-route to T.

Nodes P and W: D E H J P T W

• CTF - 2 CVL 1 CL 2 SS(V) 1 XX + 1 CL 4 DD 1 XX [Slow allowed]
  • XX can be DD, but bringing more has more chance of routing to R. It is not recommended to bring more than 4.
• CTF - 2 CVL 1-2 CA 1-2 CL + 1 CL 4-5 DD 0-1 CA(V) [Fast Required]
  • As long as the combination of of CA(V)+CL+CT = 6, as that will route you to R.

Nodes Q:

• Single Fleet - 1 CL 4 DD [Fast Required] - D E G I M Q
  • Node I is a sub-node. Bring some OASW to get pass easier. If you don't have OASW, either bring some ASW to sink some after the opening strike or pick vanguard formation and pray.
  • Node Q's fleet can show up in vanguard formation.
• Single Fleet - 1 CL 5 DD [Fast Required] - D E H I M Q
  • Node H and I are a sub-node. Bring some OASW to get pass easier.
  • If you bring 1 CL 5 DD and go through D E G I, then it will route you to L, an air-raid node.

Nodes F: D E G F

• Single Fleet - 1 CL 5 DD [Fast Required]
  • Node F is a sub-node. Bring some OASW.

Phase 2: Sinking Abyssal Jintsuu

LBAS

• You can now drop all the fighters and go full (4x) bombers for both bases. Either target both to the boss node Y or spread it out to pre-boss nodes to increase survivability. This depends on your fleet so play around. Increase range by adding Saiun if needed (you need 7 for boss).

LoS

• Required LoS to reach boss should be around >30 for Cn2, although it might be even lower.

Fleet

• Vanguard for pre-boss nodes, line abreast for submarines, diamond for air-node, and line ahead formation for boss.
• Single Fleet #1 - 1 CL 4 DD D E G I M Q Y [Fast Required]
  • Shortest route with no off-routing to L which is an air node.
  • Node I is a sub-node. Bring some OASW to get pass easier.
  • Node Q's fleet can show up in vanguard formation which makes them a lot harder to sink. If you have trouble passing, send LBAS there to help.
• Single Fleet #2 - 1 CL 5 DD D E G I L M Q Y [Fast Required]
  • Going through an additional air node at L but allows you to bring one more DD.
  • You will have to gear some ship to with high-angle guns and AACI setup to minimize the damages from this node.
  • In addition, don't forget that Node I is a sub-node, and you are recommended to bring some OASW with you.
• Single Fleet #3 - 1 CL 5 DD D E H I M Q Y [Fast Required]
  • Going through an additional sub node at L but allows you to bring one more DD.
  • Since you are going through 2 sub nodes, you should bring a lot more OASW, preferably, bring 2-3. If 3, you can sink all the submarines on both nodes most of the time since 3 submarines usually show up (Node I has a chance for 4).
• Single Fleet #4 - 2 CL 4 DD D E H K M Q Y [Fast Required]
  • Similar to above, but this one goes through an additional surface node in exchange for an additional CL. You can use this if you somehow used 2 CLs prior to this.
  • Note that you will meet the boss with fuel/ammo debuff which means you're more prone to damage while damaging less too. This route is more for an unorthodox farming than clearing.
• Combined Fleet D E G I K M O Q Y - Not recommended for Medium+
  • 0-2 CVL 0-4 CA(V) 0-3 CL 0-2 AO/AV + 1 CL 2-5 DD 0-2 CLT 0-3 CA(V) [Slow Allowed]
  • As you may notice above, you can pretty much bring anything for STF and it will still go this route. You go through 2 submarine nodes, 1 air node, and 3 surface node before reaching the boss.
    • This means that you will heavily rely on overwhelming your enemy than anything else while benefiting from STF as the main fleet hits first. This allows you to make adjust your escorts to be more flexible, such as 3 OASW DD/DE 2 CLTs 1 CL, as an example.
    • Do note that this method also cost a lot, both resources and ships, and as such is not recommended for Medium+, but still viable if desired.
