Planetary shield

Planetary shields, also known as a planetary shield generator, were large deflector shields designed to protect entire planets. These shields were used by the Galactic Empire to protect important military installations such as the security complex on Scarif, and by the First Order to protect their base of operations/superweapon, Starkiller Base.
