Navigational Deflector System
A ship travelling at warp velocity faces a significant threat of damage caused by collisions with interstellar particles or debris.
Even the tiniest particle can cause considerable damage if it strikes the ship’s hull at warp speed.
The Navigational Deflector System of a starship effectively blocks such particles from hitting the ship by using redundant high-power graviton polarity source generators, which feed subspace field distortion amplifiers.
Powerful subspace field coils direct and focus this energy into a series of parabolic “shields” that deflect small particles and debris and can also direct an accurate and powerful beam to push aside larger objects (such as asteroids).
