The three triple 16in.gun-turrets in the '''NelsonÃ¢â‚¬Â and Ã¢â‚¬Å“Rodney," plus the small 6-in guns and turrets, cost Ã‚Â£3,000,000. These 16in guns can fire a 2,461-lb projectile 35,000 yards, or 20 miles (See panel at: top of page for order of firing.) The transmitting room is deep down inside the ship. In this room all calculations for firing the guns are worked out. Not only must the distance, speed and course of the target be taken into consideration, but also speed and course etc, of attacking ship, also information as to which gun is ready for firing, and which gun is in process of loading.
