I have also added a new Electronic Hardening Tech, which can be used during the design of Active, Thermal and EM Sensors and for Beam and Missile Fire Control Systems.
Hardening incurs an additional cost based on the level of hardening but no size increase for the sensor or fire control. Each level of hardening provides a percentage chance of avoiding electronic damage (but has no effect on regular types of damage). The current values are 30%, 50%, 60%, 70%, 75%, 80%, 85%, 90% and the cost modifiers for each level are: 1.25, 1.5, 1.75, 2.0, 2.25, 2.5, 2.75, 3.0
