you only need to destory the comand centre. Make sure you are attacking the correct rouge faction for the item you are looking for. The bases must be level 30 or above. Though i think it's possible that level 25 has a very very low chance to drop them. not sure about that.

if the principle is the same as the blue prints from battle pirates then you need to also have your work shopped fully upgraded to level 10 in order to have all possible tech available.

the drop rate is low. somewhere around 3% probably, so i wouldn't hold my breath.
