The Galactic Empire was the primary user of the DSS-02 shield generator, a deflector shield generator of military caliber produced by Kuat Drive Yards, largely because of its expensive nature. Despite this, the Alliance to Restore the Republic acquired one of these generators to defend their headquarters located on the frigid planet of Hoth. The DSS-02 was capable of generating an impervious deflector shield that spanned 80 kilometers in diameter, a size sufficient to encompass the entirety of Echo Base.
