Deflector Shield
A Forcefield is produced around a Starship, space
station, planet or other facility that serves for protection against
natural hazards and enemy attacks. This shielding system is often
simply referred to as shields.
Phaser and disruptor fire cannot directly penetrate
the shields, unless the shield frequency is known and exactly matched.
Without matching, weapons may weaken the shields by draining energy
from them and their respective energy sources. Transporters cannot be
used when the shields are in place. In contrast to the shields, the
navigational deflector usually provides a forcefield which focuses on
single obstacle such as a comet.
