Normandy Shield Upgrade: Cyclonic Barrier Technology

Mass Effect 2 & Mass Effect 3
Cyclonic Barrier Technology (CBT) attempts to solve the higher-end limitations of traditional kinetic barriers. Traditional barriers cannot block high-level kinetic energy attacks such as disruptor torpedoes because torpedo mass effect fields add mass. The CBT violently slaps aside rather than halting incoming linear force. By rotationally firing their mass effect field projectors, ships create rapidly oscillating kinetic barriers instead of static ones. Shooting through the CBT is like trying to shoot at a target inside a spinning ball.

Significant drawbacks to current CBT configuration prevent its use on anything other than frigates and fighters. Its many high-frequency sensors and emitters require frequent maintenance and replacement. A partially damaged CBT can endanger its operator, who is surrounded by rotating mass effect fields skewing in unpredictable directions. Fortunately, if an emitter is damaged, the CBT corrects to become a traditional shield array, a safety feature that makes it most effective during opening volleys.
