The Javanicus isn't that different in concept from a Conquest. Choose which side you want to broadside with, put mostly cheap/PD weapons on the other side, and put either tracking missiles on the front, or expend all ammunition of your front torpedoes before you get into broadside range
Instead, I wanted to ask something: I've seen a "Joker" drone in the codex which sounds amazing, but for the life of me, I can't find any blueprint or wing anywhere. Is it only a built in wing, or can it actually be acquired?
