HMS Neptune was a Royal Navy dreadnought, intended to be the lead ship of three Neptune-class battleships, but the subsequent two ships had thicker armour and were reclassified as the Colossus class.
She was the first Royal Navy battleship that differed in her gun turret layout to Dreadnought. She had the first superfiring main armament in the Royal Navy, with the two rear turrets arranged so that one would fire over the other when shooting towards the stern. She also had two wing turrets mounted en echelon so that all five turrets could shoot in broadside although in practice this strained the hull.
She was one of the first battleships to be built with director gun-control and was used for trials of this then-novel system. She was flagship of the Home Fleet from May 1911 until May 1912 when she was transferred to the First Battle Squadron, where she remained until June 1916. 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.
