Transport Operation

Overview

Transport Operations are an event mechanic that was introduced during the Fall 2015 Event. Unlike the usual map clearing mechanic, completing a Transport Operation doesn't require you to kill the boss.

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

• The objective of the Transport Operation is to deplete a Transport (TP) gauge.
  • The amount of TP that needs to be depleted varies by difficulty.
• The TP Gauge is depleted everytime the fleet reaches a Transport Drop Off point (a node marked with a green flag) then scores at least an A rank victory at the boss.
  • Ship girls that are heavily damaged (大破), evacuated using the Fleet Command Facility or sunk are not counted towards gauge depletion.
• You do not need to sink the boss on the final run to clear the gauge.
• These maps are usually completed by a single fleet or a Transport Escort Force.

TP Gauge Depletion

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

When your fleet reaches the transport drop-off point, you will receive a notice which shows how much transport equipment you brought with your fleet which will count toward you TP score. In this case, this fleet was equipped with 10 drum canisters and 1 daihatsu.

• [math]\displaystyle{ \text{Mod}_\text{rank} }[/math] is the rank modifier. It is [math]\displaystyle{ 1.0 }[/math] for S ranks and [math]\displaystyle{ 0.7 }[/math] for A ranks.
  • Note that the TP total from ship girls and equipment is rounded down before being multiplied by the rank multiplier and rounded down again.
• [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 you successfully deplete the TP Gauge, the TP Gauge will explode before either the map is considered complete or moves on to the Boss 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.

The values appear to change from event to event. This table is very likely outdated.

Equipment	S-Rank	A-Rank
Daihatsu-class Landing Craft / Toku Daihatsu-class Landing Craft / Daihatsu-class Landing Craft (Type 89 Medium Tanks & Marines)	8.0	5.6
Drum Canister	5.0	3.5
Type 2 Ka-Mi Tank	2.0	1.4
Battle Rations / Canned Saury	1.0	0.7

Ship TP

Ship Type	S-Rank	A-Rank
Destroyer	5.0	3.5
Light Cruiser	2.0	1.2
Heavy Cruiser	0.0	0.0
Aviation Cruiser	4.0	2.8
Aviation Battleship	7.0	4.9
Seaplane Tender	9.0	6.3
Amphibious Assault Ship	12.0	8.4
Submarine Tender	7.0	4.9
Training Cruiser	6.0	4.2
Supply Ship	15.0	10.5
Light Carrier	0.0	0.0
Standard Carrier	0.0	0.0
Destroyer Escorts	0.0	0.0

Tips

• Stacking only TP depleting equipment can compromise your 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 where you can reliably A-rank the boss while taking as many TP depleting equipment as possible.
• When using a Transport Escort Fleet, the escort fleet should be where all your combat-focused ship girls are assigned. This is because the escort will bear the brunt of all combat.
• Although the daihatsu variants deplete the most TP, careful consideration should go into whether using daihatsu-capable ship girls is appropriate. Locking key ship girls when Anti-Installation is required in subsequent maps can result in disaster.
