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.

TP Gauge Depletion

TP gauge reduction is calculated using the following formula: [math]\displaystyle{ \text{TP Drain} = \biggl\lfloor \text{Mod}_\text{rank} \times \biggl\lfloor \sum^{\text{All equipment slots}} \text{TP}_\text{equip} + \sum^{\text{All ships in fleet}} \text{TP}_\text{ship} \biggr\rfloor \biggr\rfloor }[/math]

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.

• [math]\displaystyle{ \text{Mod}_\text{rank} }[/math] is the rank modifier. It is 1.0 for S ranks, 0.7 for A ranks, and 0 otherwise.
• [math]\displaystyle{ \text{TP}_\text{equip} }[/math] is the Equipment TP value. See below for details.
• [math]\displaystyle{ \text{TP}_\text{ship} }[/math] is the Ship TP value. See below for details.

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

Some equipment provides TP values when used in Transport Operations. Each instance of the equipment shown in the table below contributes towards the TP drain.

Values listed below are the baseline TP reduction values. They may vary from event to event. Please refer to the current event page for notes of any changes.

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.

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.
