Deflector shields or screens, generally referred to simply as shields, were a type of force field that surrounds a starship, space station, or planet to protect against enemy attacks or natural hazards.
Operation
Feature
Deflector shields operated by creating a layer, or layers, of energetic distortion containing a high concentration of gravitons around the object to be protected. On starships, the shield contained six sections, forward, starboard, port, aft, dorsal, and ventral. Shield energies could be emitted from a localized antenna or "dish", such as a ship's navigational deflector, or from a network of "grid" emitters laid out on the object's surface, such as a starship's hull. Since at least the -200,000 BDG, deflector shields were essential equipment on starships.
Neither matter nor highly-concentrated energy could normally penetrate a shield. When shields are "up," or energized at a high level, most matter or energy that comes into contact with the shields will be harmlessly deflected away. This was important in starship combat, as shields were essential for hull protection. When the shields were up, only minor hull damage would be expected during combat. In the 200,000 BDG - 300,000 ADG, without deflector shields weapons were capable of causing catastrophic damage to starship hulls almost immediately.
Use on fighter
Many Disco Battlecruiser (Fighter) be can use in type of plasma shield, enemy fighter or AA gun be cannot shoot a disco fighter down in battlecruiser class, disco plasma shield generator is very small and tiny can high protect from energy weapons. Disco Plasma shield power is 25x103, but disco battlecruiser be destroy by a federation starship's Mortar. (they shoot a fighter with mortar hard, that fighters can dodge quickly)
