"Queen Elizabeth" was completed with two fire-control directors fitted with rangefinders. One was mounted above the conning tower, protected by an armoured hood, and the other was in the spotting top above the tripod foremast. Each turret was also fitted with a 15-foot rangefinder. The main armament could be controlled by 'B' turret as well. The secondary armament was primarily controlled by directors mounted on each side of the compass platform on the foremast once they were fitted in March 1917, although one temporary director was fitted in November–December 1916.
