The Small Shield Dome is a defensive structure to use as fodder and give a higher chance of a draw. Only one small and one large shield dome can exist on each planet. Despite their description, and being called a “dome”, domes do not offer any sort of overarching defensive ability. They act as a single unit of fodder. Because no ship has Rapid-Fire against a Small Shield Dome, the presence of a pair of shield domes serves as a “block” against Rapid-Fire during a single combat round from fire-heavy fleets (Deathstars or Bombers). The shield increases the chance of draws occurring if the attacker uses a small attack force, such as light fighters. A small dome is invulnerable to the fire of cargos, making it a perfect defense to prevent a planet from being easily farmed. Just remember a small escort of light fighters may destroy the small dome.
