Targeting systems
The key to strong defense: without targeting systems there are no ion cannons, heavy graviton cannons, laser batteries or solar cannons.

Role
Targeting systems are the central requirement for advanced defenses: Ion cannon from level 4, Heavy graviton cannon from level 5, Positron Lighter from level 8, and Interval cannon, Laser cannon battery and Solar cannon from level 10. They don't improve any other values.
You need a Research lab at level 5 and Energy technology level 6 for it.
Background
Defensive Targeting Systems are useful to home in on targets. This technology provides an increasingly complex targeting system for advanced defense batteries and to counteract evasive tactics. The improvement of the targeting systems makes it possible to research new and more effective defense installations.
