Editing Nebula Class (section)

==DEFLECTOR SHIELDS==

The Nebula Class is equipped with a symmetrical subspace graviton field. This type of shield is fairly similar to those of most other starships. Under Starfleet Directives all vessels incorporate the nutation shift in frequency. During combat, the shield sends data on what type of weapon is being used on it, and what frequency and phase the weapon uses. Once this is analyzed by the tactical officer, the shield can be configured to have the same frequency as the incoming weapon - but different nutation. This tactic dramatically increases shield efficiency.

There are ten shield generators on a Nebula-class starship, each generating a field of 384 MW in amplitude. During alert situations, up to six shield generators can operate in parallel phase-lock, providing a continuous output of approximately 2,304 MW. Peak momentary load of a single generator has been rated at 473,000 MW for periods approaching 170 milliseconds.

The shields, when raised, operate at two distances. One is a uniform distance from the hull, averaging about 10 to 12 meters. The other is a bubble field, which varies in distance from any single point on the hull but has a common center within the ship.
