Capital armour modules for Battleships, Titans and orbital fortresses.
Level 1 unlocks Ablative Citadel; every level adds +2% module armour strength. Next level total: +{pct}%.
Research time depends on the Research Laboratory level, the Intergalactic Research Network and the universe speed.
Each level multiplies the previous cost by ×2.35, so each further level gets steadily more expensive the further you push it.
