Improvements are made to the hull, shields and armor of the Eradica Titan, improving the vessel's survivability.
There are four levels to this, with the following stats:
Level: 1 → 2 → 3 → 4
Max Hull Points increase: 713 → 1426 → 2138 → 2851
Hull Points restore rate: 0.5 → 1.1 → 1.6 → 2.2
Max Shields increase: 567 → 1134 → 1701 → 2268
Max Shield Points restore rate: 1.1 → 2.2 → 3.2 → 4.3
Max Armor Points: 2.2 →4.3 →6.5 → 8.6
Note that these levels are NOT affected by research topics; i.e., researching an increase in hull points, shield points or armor will not cause this upgrade to add more than the stipulated numbers.
