DEFLECTOR SHIELDS The tactical deflector system is the primary defensive system of the Galaxy class starship. It is a series of powerful deflector shields that protect both the spacecraft and its crew from both natural and artificial hazards. Like most forcefield devices, the deflector system creates a localized zone of highly focused spatial distortion within which an energetic graviton field is maintained. The deflector field itself is emitted and shaped by a series of conformal transmission grids on the spacecraft exterior, resulting in a field that closely follows the form of the vehicle itself. This field is highly resistive to impact due to mechanical incursions ranging from relativistic subatomic particles to more massive objects at lesser relative velocities. When such an intrusion occurs, field energy is concentrated at the point of impact, creating an intense, localized spatial distortion. To an observer aboard the starship, it appears that the intruding object has Òbounced offÓ the shield. A zero-dimensional observer on the intruding object would, however, perceive that his/her trajectory is unaffected, but that the location of the starship has suddenly changed. This is somewhat analogous to the spatial distortion created by a natural gravity well, and is typically accompanied by a momentary discharge of Cerenkov radiation, often perceived as a brief blue flash. The deflector is also effective against a wide range of electromagnetic, nuclear, and other radiated and field energies. Æ
