Hi guys,
perhaps this thread could help. It is really tricky to find some stuff, as you need to be at the right time (state) at the right place (system).
So for Military Superconductors or Military Grade Alloys you get the them in systems where the controlling faction is at war. As a war state in the galaxy map is not the most accurate indication to find the right system. Because you first need to get lucky to find a war, then get even luckier so that this war is with the controlling faction, and THEN you need to get looking for degraded emissions to have a chance at finding them.
So if anybody stumble over such system for military advanced components (Military Superconductor, Military Grade Alloys) - everybody would be grateful, if you would post it here.
Thanks,
