Can someone explain what this tech does. It is not clear how it works.



For example, once it is constructed does it keep the queue drained of industry constantly or only when the star system is under siege? So if the star system is not under siege does it allow the queue to keeping stacking industry?



What is the benefit of having a large queue verse a smaller amount in the queue? For example, suppose the queue has 3500 in it. Once a siege starts is it going to drain the queue of all 3500 to defense one and once only? Does it then keep using each turns industry production for defense?



Thanks ...

As far as I recall, the stacked industry is not consumed by that improvement.

Note that the progress of an invasion does not consume the defense. The progress bar is a separate gauge, and the system defense is a fixed value, to which the stacked industry is added. Of course, if you then use the stacked industry to produce something, that bonus is lost until the stack grows again.



So, in the case of a stack with 3500 industry in it, your system would have +3500 defense for as long as the industry remains in the stack.

Thank you, yes I see what you are saying and it makes sense. That seems to be how I'm observing it working.
