## Missile damage formula The equation for missile damage is as follows: [![MissileDamageFormula.png](https://global.discourse-cdn.com/eveonline/original/3X/8/5/85cd61e0cb9e8ef993fec7daafc6c0d5e33a1135.png)](https://wiki.eveuniversity.org/File:MissileDamageFormula.png) Here are the terms in the equation. Except for the “damage reduction factor”, these are the same as were defined in the [Basic Picture](https://wiki.eveuniversity.org/Missile_mechanics#The_Basic_Picture) section, above : | S | signature radius of target | _Note: The bigger the better_ | | --- | --- | --- | | Vt | velocity of target | _Note: The smaller the better_ | | D | base damage of missile | _Note: The bigger the better_ | | E | explosion radius of missile | _Note: The smaller the better_ | | Ve | explosion velocity of missile | _Note: The bigger the better_ | | drf | damage reduction factor | _Note: The smaller the better_ | [https://wiki.eveuniversity.org/Missile\_mechanics](https://wiki.eveuniversity.org/Missile_mechanics) --- _[View the full topic](https://forums.eveonline.com/t/signature-speed-and-chance-of-missiles-in-a-certain-orbit-and-turrets-in-angels-formula-calculation/200368)._
