Efficient Shielding is a technology on the Exploration and Expansion technology tree with a research cost of 130 . It unlocks one Ship Class, needs research in Xenobotany, and allows further research in Applied Casimir Effect.
"By augmenting the natural magnetic characteristics of the hull material and using lighter alloys in construction, this improved ship design gives bonuses to tonnage and improves kinetic and missile defense."
"This technology is important for fleet development. More heavily armed than the basic Corvette, it is more weaponized. This allows for an advantage, especially in tight battles when fitting long-range weapons such as lasers and missiles is essential. These weapons rely on achieving more hits to overload enemy defenses."
