This page is for "Effective Line of Sight" (ELoS), also called "Fleet LoS", as it pertains to branching requirements. Certain maps require the fleet to hit a certain LoS threshold in order to get routed to the boss or pre-boss. As a rule LoS from equipment is more important than ship LoS when determining ELoS.

For a details on the LoS Line of Sight stat, please see Stats.

Calculating LoS

Formula 33

Formula 33, sometimes referred to as F33 is the most accurate "Fleet LoS" calculation formula known. It is described as follows[1]:

[math]\displaystyle{ \begin{align} \phi &= \sum_{s \in \text{Ships}} \sqrt{L_s} + C_{n} \sum_{l \in \text{Slots}}C_{l} ( S_{l} + S_l^{\star} ) - \lceil Q \times H \rceil + 2M \\ S_l^{\star} &= C_l^{\star} \cdot \sqrt{\bigstar_l} \end{align} }[/math]

With:

  • [math]\displaystyle{ L_s }[/math] the ship's base LoS Line of Sight.
    • Total LoS Line of Sight of visible fit bonuses should be added to this part, unlike equipment improvement bonuses.
  • [math]\displaystyle{ C_{n} }[/math] the Node factor, it represents the weighting of the formula that is known to vary across different maps and nodes. See following section for more details.
  • [math]\displaystyle{ C_{l} }[/math] the equipment multiplier (see bellow),
  • [math]\displaystyle{ S_{l} }[/math] the displayed LoS value of the equipment, excluding visible fit bonus,
  • [math]\displaystyle{ S_l^{\star} }[/math] the equipment's Improvement Improved bonus to eLoS (see [math]\displaystyle{ C_l^{\star} }[/math] bellow),
  • [math]\displaystyle{ Q }[/math] the HQ level modifier, varying depending on the map:
    • 0.35 i 5-2 and 6-3.
    • 0.4 otherwise.
  • [math]\displaystyle{ H }[/math] the HQ level.
  • [math]\displaystyle{ M }[/math] the number of empty ship slots in the fleet:
    • 0 for 6 ships fleet,
    • +1 increase per missing ship,
      • This value can increase mid-sortie if a ship is sunk or retreated.
    • -1 for a full Striking Force Fleet (7 ships).

  • [math]\displaystyle{ C_l^{\star}=0 }[/math]

Equipment LoS weighting modifier

  • Also known as node factor.
  • Depending on the map, equipment is weighted with more importance.
  • It is denoted as Cn in the formula.
  • See the table below for Cn values used by each map.
  • Ship LoS is less effective in those maps with higher equipment weight modifiers.

Estimated LoS

Data sourced from TsunDB. Values are the lowest and highest reported LoS for routing. Please note that there may be some margin of error due to random routing.

FAQ

Q: Why do I keep getting offrouted?

A: Double check that your fleet LoS according to relevant formula meets the LoS threshold for the map. Viewers such as KanColle Command Center Kai, Poi Viewer, KCANotify, KanColle Viewer and Electronic Observer can calculate your fleet's LoS easily for you.


Q: How do I increase my LoS?

A: Reconnaissance seaplanes are the fastest way to raise LoS. The other easy way is to stack radars. Upgrades to reconnaissance seaplanes are also a good way to increase LoS when slots are limited. It is not recommended to stack carrier-based recons or seaplane bombers because too many can compromise the combat ability of your fleet. Another way is to level your ships. Because LoS increases as you level, marrying your ships means their LoS stat can go even higher.


Q: I had enough LoS, how did I get off routed?

A: Planes that are wiped out no longer contribute to LoS. If you were depending on bombers to hit the LoS threshold, you can fall under the threshold when encountering heavy enemy anti-air.
