Class 4 and Class 5 Ion Storms can drag starships far from where a Commander wants them to be, damaging their hulls in the process. In an effort to limit the damage done by an Ion Storm, it is possible to develop an Ion Shield for your starbases.
With an Ion Starbase Shield, starships in orbit around a planet with a starbase will no longer be damaged or dragged by Ion Storms. Ion Storms will still cause cloaking to fail. This feature only protects starships owned by the player who owns the planet.
