Defense systems
+10% structure per level for ships and defenses – the armor that counts once the shield is down.

Effect
Defense systems increase the structure – in other words the armor – of your ships and defenses by 10% per level. The structure takes over once the shield has been broken: if it drops to zero, the unit is destroyed. It also helps your defenses withstand particle beams from a Particle cannon.
It requires a Research lab at level 5. Defense systems unlock the Phoenix (level 5) and the Positron Lighter (level 6).
Background
The Defense Systems protect the ship from being destroyed and increase the strength of the ship's entire structure. Its structure increases by 10% for each level completed, thus making the ship more resilient to an attack. That's why it's highly recommended to research this technology as soon as you can.
