Vanguard Formation (警戒陣): The Spear-looking formation Edit

  • Vanguard Formation
  • Striking Force Vanguard Formation
Introduced in Fall 2017 Event for the first time along with the Strike Force mechanic, the vanguard is a defensive formation which affects the ships based on how they are positioned in the fleet.
  • Your fleet is divided evenly between a top half and the bottom half. For example, a fleet of 6 ships will be divided 3/3, with the first 3 ships belonging to the top half and the last 3 ships belonging to the bottom half.
  • However, in case your fleet consists of an uneven number of ships, the top half will take the lower number. For example, if you're using a Strike Force which consists of 7 ships, your top half will consist of the first 3 ships, while the bottom half will be the last 4 ships. The term "top half" and "bottom half" will be used.

Modifier Edit

Fleet Halves Damage Modifier Evasion Bonus? Aggro?
Accuracy Modifier
Shelling Torpedo ASW Night Aerial
Top half 50% 100% 100% 50% 100%
80% ??? ??? ??? ???
Bottom half 100% 100% 60% 100% 100%
120% ??? ??? ??? ???

Keep in mind that Vanguard has a Night Battle modifier that is not a 100%, which is unique among the available formations. For nodes where you want to maximize your firepower as much as you can, especially on boss nodes, Vanguard is generally undesired.

The ASW capable ships benefit the most from the top half while those who damage through shelling and night attacks benefit the most when placed in the bottom half. Torpedo modifier remains 100% regardless of where the ship is placed in the fleet.

Note that in the scenario that a Shelling Support is used, the Shelling Support will receive a 50% firepower modifier as well when Vanguard is selected. This is applied on the whole support fleet, so placing weaker ships at the top will not solve this problem.

Evasion bonus & Aggro effectEdit

When the Vanguard formation is selected, all your ships in the fleet will obtain a post-cap evasion bonus [1]. While everyone in the fleet will gain an evasion bonus, the amount of evasion you gain is based on 2 things:

  1. Is the ship a DD?
  2. Is the ship part of the top or the bottom half?

The rough estimates of the evasion bonus are as followed:

  • Top half (including the 4th ship)
    • Non-DD: +5% Evasion
    • DD: +20% Evasion
  • Bottom half (excluding the 4th ship)
    • Non-DD: +20% Evasion
    • DD: +40% Evasion

Regarding aggro effect, the bottom half is attacked more often than usual, which is supported by its higher evasion.

AirstrikesEdit

A test has been done albeit roughly regarding Vanguard Formation's effect on Air Raid nodes. A conclusion was reached as followed [2]:

Ship Slots Evasion Bonus? Aggro?
First half
Second half

While the aggro effect is still there, you do not gain any evasion bonus against airstrikes. In other words, your evasion will be the same as in Diamond formation, except with a worse AA modifier of 110% instead of 160%.

  • Your bottom half will suffer the most from airstrikes and you do not have evasion bonuses to compensate for it this time.

Is there any ship locking? Edit

Why can't I sortie to E-? HELP!!! Edit

If you follow this simple 3 step pathway, you should be on your way to sortieing to E_

  1. Correct Map
    • 'You'd be surprised
  2. Correct Fleet
    • Single Fleet for Single Fleet maps
    • Combined Fleet for Combined Fleet maps
    • Transport Escort fleet for Transport Escort fleet maps etc.
    • Also, on Medium/Hard difficulty, you mustn't have any ships that have been ship locked to a different tag colour. See here for a hopefully foolproof explanation
  3. Minimum Requirements
    • Must have a 75% sortie win ratio
    • Must have 5 empty ship slots for new ships
    • Must have 20 free equipment slots

What is/are the drop rates for XXXXX, YYYYY, ZZZZZ ship? Edit

Currently there are three sites with database on the drop rates. Information from those sites may not be neither complete nor accurate however they still form as part of the sources in terms of drops and drop verification apart from information sourced internally from the wiki itself:

For more information on how to navigate around these sites you may wish to refer to this blog entry.

What does this mean? I can't select the plane anymore for support. Edit

What does this mean?

Caution: Un-equipping a plane from an air base will make that plane unavailable for 12 minutes while it is being "relocated"
