Deflector shield

Memory Beta, the wiki for licensed Star Trek content.

The Deflector shields (or more commonly referred to simply as shields) are an electromagnetic field that can be projected around a starship, starbase, or planet and act as the first form of defence against enemies or natural hazards.

By the 22nd century, humans had only developed basic deflector shields projected from a deflector dish which allowed them to operate at warp speeds but had to resort to polarized hull plating in tactical situations. However many species in the Alpha and Beta Quadrants had developed more advanced shielding technology by the 2150s, these included the Andorians and the Klingons.
