Ok. So last I remember, Cluster Missile in this ship, with a Positron Cannon 17 dealt a base damage of around 15,280 dmg. Not bad considering it does not have the radiation cloud. It has 5 warheads that deal 3750 dmg each, up to 3 of them can lock into a single target. There is a catch: you either hit with the main missile, or cluster and spread the damage. Its pretty chaotic and fun to use.
By reasons not even specified in the last patch notes, apparently there was a “ghost nerf” to this module. The Cluster Missile currently got nerfed from (Positron Cannon 17 as main weapon) 15,280 dmg to 11,696 dmg.
