|Neptune. First British battleship with super-firing turrets. They were arranged this way aft rather than forward as it was felt that the concentration of weight forward would make the ship a poor sea boat. The sighting hoods in British turrets were in the turret roof so there was risk of concussion if the turrets fired over the top of each other, hence the British reticence to adopt the super-firing arrangement.|

The first significant change since the original Dreadnought. The armament was rearranged with the rear turrets now superimposed and the wing turrets staggered to allow some cross deck firing to allow all 10 guns to fire on the broadside. The secondary was reduced and guns were no longer on the turret roofs, an acknowledgement that these potions were too exposed and supplying them with ammunition in action could be hard. Crew 756.

|HMS Neptune in July 1914. When built she was fitted with a director and used for trials. Although there were problems with this early installation further trails were carried out with a modified design in HMS Thunderer and by the end of World War 1 directors were standard equipment on British warships.|
