| + | ===Fleet Anti-Air Defense (new formula)=== |
| + | '''Note: The formula for this section is for the player's side. The formula for abyssal ships is strongly suggested to be different.''' |
| + | |
| + | After plane loss from fighter combat is calculated, for each enemy bomber slot ({{Seaplane}} / {{RedPlane}} / {{BluePlane}}), a random ship (''defending ship'') is assigned to defend against that slot via AA fire. |
| + | *Fighters {{GreenPlane}} are not subject to AA fire from ships. |
| + | *The ship performing AA fire is not necessarily the same ship that the bomber will attack; the ship performing AA fire may not even be a surface ship. |
| + | The defending ship's '''weighted anti-air value''' will be used in calculations for two types of anti-air shootdowns: ''percentage shootdown'' and ''fixed shootdown''. |
| + | *Both shootdowns have 50% chance to succeed; failing means no planes are shot down for that part of the calculation. |
| + | *Percentage shootdown will be done prior to anti-air cut-in and fixed shootdown calculation. |
| + | *Friendly units additionally get a guaranteed shootdown of 1 plane (per slot) after the percentage/fixed shootdowns; this applies even if both percentage shootdown and fixed shootdown fail. (Enemy fleet does not get this 1-plane guarantee) |
| + | |
| + | ''There was a bug causing the formation anti-air modifier and fleet anti-air bonus to not function; this was fixed on June 26, 2015.''<br> |
| + | Fleet Anti-Air Bonus is currently suggested to only apply to ''fixed shootdown'' calculation. |
| + | |
| + | For each ship, the formula for its weighted anti-air value is calculated as follows: |
| + | <center><math>\text {Weighted Anti-Air Value} = \text{Ship's Innate Anti-Air Value} + \sum^\text{All equipment slots in fleet} \text{[ Equipment Multiplier} \times { \text {Equipment's Anti-Air Value} + 0.7 \times \sqrt{\text{Equipment's Improvement Level}} } \text{ ]}</math> |
| + | </center> |
| + | where equipment multiplier is shown in the table below: |
| + | {| class="wikitable" |

| + | |
| + | Multipliers for equipment not listed are not confirmed at this time. |
| + | |
| + | <math>\text {Percentage Shootdown (in percent)} = \text {Weighted Anti-Air Value} \div 400</math><br> |
| + | *Alternative suggestion of <math>\text {Percentage Shootdown (in # of planes)} = \text{Floor(Weighted Anti-Air Value} \times 0.9 \text{)} \div 360 \times \text{Number of Planes in Slot}</math> exists) |
| + | <math>\text {Fixed Shootdown (in # of planes)} = \text {Floor(Weighted Anti-Air Value} \div 10 \text{)}</math> |
| + | |
| + | ====Example of shootdown calculation==== |
| + | [[Akizuki]] (Innate AA value of 116, equipped with two [[10cm Twin High-angle Mount + Anti-Aircraft Fire Director|10cm HA+FD *+6]] and an [[Type 13 Air RADAR Kai]]) is defending against [[Aircraft Carrier Princess]]'s torpedo bomber slot (with 56 planes). Ignoring all other contributing factors such as Anti-Air Cut-In, fighter combat, and bonus from other members in fleet,<br> |
| + | <math>\text {Akizuki's Weighted AA Value} = 116 + 4 \times (10 + 0.7 \times \sqrt(6) ) \times 2 + 3 \times 4 = 221</math><br> |
| + | Thus, the values for the shootdown are calculated as follows:<br> |
| + | <math>\text {Akizuki's percentage shootdown} = 221 \div 400 = 0.55 = 55 \%</math><br> |
| + | <math>\text {Akizuki's fixed shootdown} = \text{Floor(} 221 \div 10 \text{)} = 22</math><br> |
| + | The shootdown takes place in the order of percentage, then fixed, then guaranteed, so there are 4 possible outcomes: |
