Foreign Plane Bonuses have returned and should be examined when planning equipment setups. The following bonuses are applied:

Ships using planes get bonuses based on the different categories of bonuses ɑ/β/γ, A, and B.
- The ɑ/β/γ groups are the general foreign plane bonuses, being divided into three "levels" (γ>β>ɑ) and being both map-wide and node-specific,
- Group A are French and British bonuses divided into three sub-categories:
  - A1 are French seaplanes,
  - A2 are British seaplanes,
  - A3 are Swordfish.
- B# bonuses are primarily for LBAS (with ship-based & land-based planes), with the ship-based planes also providing the same bonuses to ships, and being divided into two "levels" (B2>B1)
  - Heavy Bombers also have similar bonuses

Notes

These bonuses work for all ships and for all attack types, including: LBAS, jet assault, airstrikes, air/surface shelling, and night attacks.
Bonuses from a same line or column do not stack.
Map-wide bonuses and node-specific bonuses always stack.
Bonuses still work for planes equipped in 0-slot for ships.
Bonuses do not work on 0-slot for LBAS.

- On the 2024-07-31 update, the FR-1 Fireball/SB2C-5 bug has been fixed and other bonuses have been added.

Tips

Carriers:
1. Try to equip one plane from each column and row
2. For example: ɑ/A3 + β/B1 + γ/B2
- This also applies to ships that carry multiple plane types in normal setups.
Other Ship Types:
- As only one seaplane is generally equipped on a ship, pick γ>β>ɑ and then the highest bonus among groups A or/and B depending on the node.

For Group 1, Group 2, and Group 3 bonuses, having one equipment from the group is enough to have the bonus.
- Equipping a second gear from the same group will not provide any additional bonus.
- The bonus groups stack with each other.
Do not confuse the balloon mechanic fleet-wide buff with this event bonus that only buffs the individual ship equipped with it.

Map Overview

E1 is a single fleet one phase map, with 2 unlocking phases before the boss Phase.

2 LBAS are available on this map:
- Only 1 can be set on Sortie, the other being limited to Defense,
This map uses 1 lock:
- Home Fleet (reused in E-2 & E-3)

Barrage Balloons can be deployed on installation nodes I M.

Phase 0.3: Unlock The Second Starting Point

The following steps have to be performed to unlock the second gimmick phase.

	C2	F	H
Hard	S x2	Reach x2	Reach x2
Medium	S?	Reach	Reach
Easy	S?	Reach	Reach
Casual	?	?	?

Single Fleet: 0-1 CV, CL, 4 DD
Route: 1 A B C C2
The CV can be a throwaway as they will not be used in the main phase.
Have DD setup for ASW if B is an issue.
LBAS Range to C2 is 7. There is no air power at the node.

Refer to C2 for fleet composition
Route: 1 A B C C1 E F

Refer to C2 for fleet composition
Route: 1 A B C C1 E G H
If a ship taiha at this node, continue trying to reach H as this is an end node, and no combat is present.

Phase 0.6: Unlock The Boss

The following steps have to be performed to unlock the boss.

	B	L	K	LBAS
Hard	S	S x2	S	AS
Medium	A	S? x2	-	AS
Easy	-	A? x2	-	AS
Casual	-	B x2	-	AS

Single Fleet: CV, CL, 4 DD
Route: 1 A B
Bringing ASW is required to clear the node.

Single Fleet: 1 BB, 1 CL, 4 DD
Route: 2 J G K L
Comp is similar to the Boss killing comp used for Phase 1.
Bringing ASW is required to clear K.

This can be achieved while running through other nodes by having LBAS set on air defense.

CV is required in the fleet to start at Point 1 once Point 2 is unlocked, notably to reach B.

Phase 1: Boss HP

Single Fleet: 1 (F)BB, 1 CVL, 1 CL, 2 DD, 1 AV (Fast Fleet)
Route: 1 A B C C2 L M

Single Fleet: 1 (F)BB, 1 CL, 4 DD (Fast Fleet)
Route: 2 J G L M

LoS Check: ??
Using Boss Support is highly recommended for Last Dance for higher difficulties.
The boss is an Installation.
- Anti-Installation Equipment are highly recommended to defeat both the Boss and the Pillboxes ("hard skin installations").
LBAS Range = 5 AD/AP = 33/65 for HARD
There are PT boats that appear along the way to the boss and at the boss node's Last Dance.

Anti-PT boat

Unlike most standard Abyssals, "PT boats" ( & ) are "very small and fast".

All ship types suffer a severe accuracy and firepower penalty against PT boats.
Attacking them with larger guns is not very effective, smaller guns being recommended instead.
Support Expeditions are not affect by any of the following^[1].

Attack formula against PT boats
The Attack formula against PT boats:^[2]^[3] Jet Assault & Airstrike [math]\displaystyle{ \text{Damage}_\text{PT}= \text{Atk}_\text{post-cap} \times \text{Rand} [0.5 ; 0.8] }[/math] LBAS^[4] [math]\displaystyle{ \text{Damage}_\text{PT}= \text{Atk}_\text{post-cap} \times \text{Rand} [0.4 ; 0.7] }[/math] Shelling [math]\displaystyle{ \text{Damage}_\text{PT}= ( 0.3 \times \text{Atk}_\text{post-cap} + \sqrt{\text{Atk}_\text{post-cap}} + 10 ) \times \prod^{All Equipment}{\text{Mod}_\text{EquipmentAtk}} }[/math] Opening & Closing Torpedo Salvos [math]\displaystyle{ \text{Damage}_\text{PT}= 0.3 \times \text{Atk}_\text{post-cap} + \sqrt{\text{Atk}_\text{post-cap}} + 10 }[/math] Night Battle Night Battle data are unclear yet. With [math]\displaystyle{ \text{Atk}_\text{post-cap} }[/math] the post cap attack power defined here, [math]\displaystyle{ \text{Mod}_\text{EquipmentAtk} }[/math] the bonuses given by equipment, described below.

Accuracy formula against PT boats

The Accuracy formula against PT boats:^[5]^[6]^[7]^[8]

[math]\displaystyle{ \text{Hit Rate}_\text{vs.PT} \text{%} = \Big\lfloor ( 0.3 \times \text{Accuracy}_\text{Atk} + \sqrt{\text{Accuracy}_\text{Atk}} + 15 ) \times 1.2 \times \text{Mod}_\text{Ship} \times \Big( \prod^{All Equipment}{\text{Mod}_\text{EquipmentAcc}} \Big) \times \text{Mod}_\text{Night} \Big\rfloor - \text{EVA}_\text{PT} + 1 }[/math]

With

[math]\displaystyle{ \text{Acc}_\text{Atk} }[/math] the standard accuracy described here
- PT boats are "DDs" in the game, so the [math]\displaystyle{ \text{Mod}_\text{formation} }[/math] for vanguard is 1.1 during shelling, and 1.2 during the torpedo phase.
- Historical accuracy bonuses during Events are included in the Standard Accuracy Term, i.e. it is affected by the [math]\displaystyle{ \text{Mod}_\text{PT} }[/math] modifier.
[math]\displaystyle{ \text{EVA}_\text{PT} }[/math] the PT estimated evasion described bellow,

PT boats stats
Type	Luck	Eva	[math]\displaystyle{ \text{EVA}_\text{PT} }[/math]
Type	Luck	Eva	Line Ahead	Echelon	Line Abreast
PT Imp Pack	?	?	81?	87?	?

Schnellboot Imp Pack	?	?	?	?	?
Schnellboot Imp Pack II	?	?	?	?	?
Schnellboot Imp Pack Elite	?	?	?	?	?

The main Accuracy modifiers are

[math]\displaystyle{ \text{Mod}_\text{Amagiri} }[/math] being include in [math]\displaystyle{ \text{Acc}_\text{Atk} }[/math]:
- 65 for Amagiri Kai Ni/D
- 35? for DD and DE adjacent to Amagiri Kai Ni/D.
- 0 otherwise.
[math]\displaystyle{ \text{Mod}_\text{Ship} }[/math] the bonus given by ship types, described below,
[math]\displaystyle{ \text{Mod}_\text{EquipmentAcc} }[/math] the bonuses given by equipment, described below,
[math]\displaystyle{ \text{Mod}_\text{Night} }[/math] being 0.7 during night battle, 1 during day battle.

Amagiri Kai Ni/D
has the ability to prioritize focusing on attacking PT imps with significantly increased accuracy if any are present.

DD placed in the composition slots above and below her will gain a noticeable accuracy boost and will prioritize attacking PT boats if any are present.
The PT boat targeting rate is 100% for all affected ships ^[9].

During Events, some special bonuses may be added, with "historical" ships and equipment gaining some accuracy bonuses^[10].

Notes

It is recommended to use anti-PT setups on DDs only, such setups compromising overall combat effectiveness.
Having a Reinforcement Expansion is important because it can save a ship slot by containing a machine gun or skilled lookouts.
Combining equipment is recommended to see significant boosts to accuracy.
The Ka-Tsu Tanks
bonus does not stack with the Armed Boats
ones.
Using other setups improving accuracy is also advisable:
- Hidden accuracy bonus setups,
- Sparkled ships.

Trivia

M Node is Brest, during WW2 it was the home port for the French Navy and was where the famous Force de Raid was based and sortied from until their transfer to Mers El Kebir during the French capitulation. Then it fell under German control and was used from 1941 as the dock and home port for the German Surface fleet including Scharnhorst, Gneisenau, Prinz Eugen, U-Boats, S-Boats, and more. It was also the site of a major engagement named "Battle for Brest" which lasted more than 2 months and resulted in massive destruction of the city.

B Node is in the area of the Celtic Sea. During WW2 this site was a common area passed by merchant shipping and also a hunting ground for German U-Boats which could explain the abyssal submarine presence in the node.

F Node is in Plymouth which is a major Naval Port in Great Britain. In the context of Operation Catapult, it was also the site of an incident wherein the British Forces forcefully boarded the French Vessels that escaped the Fall of France that were docked there. This led to the death of several French and Royal Navy personnel. The same happened in Portsmouth and Alexandria. This seizing of French Vessels was part of the lead-up to the Attack on Mers El Kebir.

H Node is Portsmouth a major port and base for the Royal Navy during WW2 and launch point for major Operations in the English Channel, Atlantic, and Normandy as well as a prime target for the German Forces during the war resulting in multiple raids on the port city.

I Node is in the area of Le Touquet, which was originally an area where the Allied Forces were stationed until the Fall of France. Under German occupation, it became a garrison and was a staging ground for Operation Sealion. It also boasted extensive German bunkers and fortifications which could explain the presence of Abyssal Pillbox Imps. It was also the target for diversion operations such as Operation Starkey and Operation Glimmer.

K Node is around the Channel Isles: Jersey and Guernsey which were occupied by the Germans and had immense fortifications as well as constant German surface and subsurface patrols. Which could explain the abyssal Submarines.

Nodes G and J are on the English Channel, during WW2 this was patrolled by German surface and subsurface forces along with the threat of Air Raids from German Aibases in Northern France. These were a common threat for Merchant Shipping and Allied Forces until the Invasion of Normandy.

AirBase in Southern England is situated around London. This could be any number of Airfields such as Hendon, Northol, Fairlop, Heston, Croydon, Biggin Hill, Kenley, Hornchurch, or Gravesend.
