HMS Neptune was a Royal Navy dreadnought, intended to be the lead ship of three Neptune-class battleships, but the subsequent two ships had slightly thicker belt armour and were reclassified as the Colossus class.
[edit] Design
She was the first Royal Navy battleship that differed in her gun turret layout to Dreadnought. She had two wing turrets staggered en echelon so that all five turrets could shoot in broadside, although in practice the blast damage to the superstructure and boats made this impossible except in an emergency.
However, the staggering of the wing turrets was achieved in an increased hull length of only 10 feet compared to the preceding St. Vincent class.
To achieve the staggering with such a small increase in hull length, the ship was equipped with superfiring rear turrets; arranged so that one would fire over the other when shooting towards the stern. She was first Royal Navy ship to have superfiring main armament (the American battleship, USS South Carolina, launched in 1908, was the first battleship anywhere to have superfiring main turrets). However, the upper of the two turrets could not fire within 30 degrees of the stern without the lower turret being damaged by blast through its sighting hoods.[1]
A further saving in length was achieved by siting the ship's boats on a flying deck over the two en-echelon turrets to reduce the length of the vessel. However, had the flying deck been damaged during action, they may have fallen onto the turrets, immobilising them. The bridge was also situated above the conning tower, which risked similarly being obscured if the bridge collapsed.[1]
She was one of the first battleships to be built with director gun-control and was used for trials of this then-novel system. [2]
[edit] Service history
She was flagship of the Home Fleet from May 1911 until May 1912 when she was transferred to the 1st Battle Squadron, where she remained until June 1916, just after the Battle of Jutland.[3] She was accidentally struck by SS Needvaal in April 1916 but no serious damage was done. She was present at the Battle of Jutland as part of Admiral Jellicoe's Battle Fleet. She fired only 48 12 inch (300 mm) shells but is credited with scoring several hits on the German battlecruiser Lützow.
After the war she was quickly transferred to the reserve fleet and subsequently scrapped.
