Kinetic screen

Kinetic Screens utilized the manipulation of gravity fields to deflect incoming projectiles, such as those from railgun, as well as incoming missiles and debris. Essentially, projectors maintained a wall of repulsive gravity. This wall prevented anything from hitting the ship.

This wall was kept up by one or more dedicated generators, as more and more material impacted the screen the generator was subjected to more and more stress. Eventually emergency safety systems disengaged the screen to prevent the generator from overloading. Overriding these safety systems would keep the screens up for slightly longer, but eventually the generator would overload and cause massive internal damage to the ship.

The gravity "wall" was projected by various projectors placed around the ship, the number of which varied depending on the size of the ship. In general the coverage of each projector overlapped enough that if one was lost, the two adjacent to it could compensate, but this would weaken overall screen strength.
