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

 
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.

The objective of the Transport Operation is to deplete a Transport Point (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 TaihaHeavily Damaged (大破), evacuated, or Sunk 撃沈, 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:

TP Depletion Formula
[math]\displaystyle{ \text{TP}_\text{drain} = \Bigg\lfloor \text{Mod}_\text{rank} \times \bigg\lfloor \text{Mod}_\text{map} \times \Big( \sum_\text{All equipment} \text{TP}_\text{equip} + \sum_\text{All ships} \text{TP}_\text{ship} \Big) + \sum_\text{All equipment} \text{TP}_\text{tank} \bigg\rfloor \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{tank} }[/math] the additional equipment TP value given by tanks during "Landing Operation" only, described below,
  • [math]\displaystyle{ \text{TP}_\text{ship} }[/math] the ship TP value, described below,
  • [math]\displaystyle{ \text{TP}_\text{equip} \text{ & } \text{TP}_\text{tank} \text{ & } \text{TP}_\text{ship} }[/math] are set to 0 for all ship being either TaihaHeavily Damaged (大破), evacuated, or sunk.
  • [math]\displaystyle{ \text{Mod}_\text{map} }[/math] the map nerf mod, reducing the value of regular TP sources during "Landing Operation" only,
Notes
  • The total amount of TP is computed separately for each fleet in a combined fleet, with a rounding down on each.
  • For Kinu Kai Ni, the modifiers are applied to her and her innate DLC separately.
 
Once the TP Gauge is successfully depleted, it will explode before either the map is considered complete or moves on to another Gauge.
Notes
  • The fleet total TP value for S ranks can be seen ingame via the "Flight II-A mode".

Equipment TP

The following equipment increase the TP drain for Transport Operations.

  • Those bonuses stack infinitely, 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
  Landing Forces 0 0
Notes

Ship TP

The following ship types increase the TP drain for Transport Operations:

Ship Type S-Rank A-Rank
AO Fleet Oiler 15.0 10.5
LHA Amphibious Assault Ship 12.0 8.4
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

Kinu Kai Ni

Kinu Kai Ni act as she add an inate Daihatsu Landing Craft.

  • In normal conditions she therefore brings 10 TP points instead of 2.

During "Landing Operation", the TP drain formula is altered, with regular modifiers being nerfed, and tanks gaining additional bonuses.

  • [math]\displaystyle{ \text{Mod}_\text{map} }[/math] is the map-dependent nerf moddifier, reducing the value of regular TP sources.
Event Map [math]\displaystyle{ \text{Mod}_\text{map} }[/math]
Spring 2025 Event E-2 0.65
E-5 0.8
Fall 2025 Event E-2 0.75

Tank TP

The additional "tank bonus" given by equipment Landing Operations is as follows:

Landing Operation - [math]\displaystyle{ \text{TP}_\text{tank} }[/math]

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.
