Transport Operation

Example of an event map with a transport operation from Winter 2016.

Transport Operations are an event mechanic that was introduced during the Fall 2015 Event. Unlike the usual map-clearing mechanic, completing a Transport Operation does not require to kill the boss.

Overview

The objective of the Transport Operation is to deplete a Transport (TP) gauge/bar.

• The amount of TP that needs to be depleted varies by difficulty and map.

The TP Gauge is depleted each time the fleet reaches a "Transport Loadout Node" (a node marked with a green flag) and then scores an A+ rank at the boss, with S ranks depleting more points than A ranks.

• Ships that are heavily damaged (大破), evacuated, or sunk, are not counted towards gauge depletion.

The boss does not need to be sunk at any point.

• Sinking it may be advisable to get S ranks and so deplete the gauge faster.
• In the eventuality there is no boss node after the TP node, then just reaching the node is enough, counting as an S rank all the time.

Those phases are usually completed by a single fleet or a "Transport Escort Force" (TCF).

1-6 behaves similarly to Transport Operations, but is not one, being much simpler.

Spring 2025 Event's E-2 introduced a new type, the "Landing Operation", where "tanks" do bring more points.

TP Gauge Depletion

TP gauge reduction is calculated using the following formula:

Damage Formula

[math]\displaystyle{ \text{TP}_\text{drain} = \Bigg\lfloor \bigg\lfloor \Big( \sum_\text{All equipment} \text{TP}_\text{equip} + \sum_\text{All ships} \text{TP}_\text{ship} \Big) \bigg\rfloor \times \text{Mod}_\text{rank} \Bigg\rfloor }[/math] With [math]\displaystyle{ \text{Mod}_\text{rank} }[/math] the rank modifier, being: 1.0 for S ranks, 0.7 for A ranks, 0 otherwise. [math]\displaystyle{ \text{TP}_\text{equip} }[/math] the Equipment TP value, described below. [math]\displaystyle{ \text{TP}_\text{ship} }[/math] the Ship TP value, described below. It is 0 for all shipw being either heavily damaged, evacuated, or sunk.

When the fleet reaches the "Transport Loadout Node", a notice will show how much transport equipment is brought with the fleet which will count toward the TP score. In this case, this fleet was equipped with 10 Drums and 1 Landing Craft.

Once the TP Gauge is successfully depleted, it will explode before either the map is considered complete or moves on to another Gauge.

Equipment TP

The following equipment increase the TP drain for Transport Operations.

• Those bonuses stacks infinitly, regardless of the exact equipment.

Transport Operation
Equipment	S-Rank	A-Rank
Landing Craft	8.0	5.6
Drum Canisters	5.0	3.5
Amphibious Vehicles	2.0	1.4
Rations	1.0	0.7

Notes

• Even so the Underway Replenishment icon is displayed on TP nodes, they do not contribute to TP gauge depletion.

Ship TP

The following ship tyupes increase the TP drain for Transport Operations.

• Those bonuses are 0 for all ships being either heavily damaged (大破), evacuated, or sunk.

Ship Type		S-Rank	A-Rank
AO	Fleet Oiler	15.0	10.5
LHA	Amphibious Assault Ship	12.0	8.4
Kinu Kai Ni		10.0	6.8
AV	Seaplane Tender	9.0	6.3
BBV	Aviation Battleship	7.0	4.9
AS	Submarine Tender
CT	Training Cruiser	6.0	4.2
DD	Destroyer	5.0	3.5
CAV	Aviation Cruiser	4.0	2.8
CL	Light Cruiser	2.0	1.2
SSV	Aircraft Carrying Submarine	1.0	0.7
BB	Battleship	0.0	0.0
FBB	Fast Battleship
CV	Standard Carrier
CVB	Armored Carrier
CVL	Light Carrier
CA	Heavy Cruiser
CLT	Torpedo Cruiser
DE	Coastal Defense Ships
SS	Submarine

• Here, Kinu Kai Ni stacks the base CL bonus with the Landing Craft one, thanks to her innate Daihatsu Landing Craft.

Tips

• Stacking only TP equipment can compromise the ability to score an A+ rank and result in no depletion at all. On the other hand, focusing too much on offensive capability may result in minimal gauge depletion even on an S rank.
  • It is ideal to find a balance ranking A+ rank the boss while taking as much TP equipment as possible.
• When using a Transport Escort Fleet, the escort fleet should be where the combat-focused ship girls are assigned, since the escort may also attack at night.
• Although Landing Craft deplete the most TP, careful consideration should go into whether using Landing Craft-capable ships is appropriate. Locking key ship when Anti-Installation is required in subsequent maps can result in disaster.
