HMS Neptune was built as the first ship of the new class whose design or weapon deployment was not based on the HMS Dreadnought concept. However, the next two ships (HMS Colossus and HMS Hercules) were given thicker armour and were included in the new Colossus class. As I have already mentioned, in particular the weapon deployment (and thus the hull design) was novel in the Royal Navy. It was the first ship to have the main artillery turrets placed in superposition, i.e. the guns of the upper turret fired over the lower turret. Usually turrets arranged in this manner are placed on the bow of the ship to enhance the forward firing capability of the pursuing ship. In this case, however, the designers decided to place these turrets aft, mainly because the increased weight of the forward part of the ship would impair the nautical characteristics of the vessel. Another unusual feature of the ship was the location of the wing (side) turrets. Unlike previous classes, the side turrets were not placed symmetrically in the same position on either side of the ship, but were offset from each other. The side turrets could thus fire to both sides, unlike their predecessors. Thus, ideally, 10 barrels could be fired per side - in previous designs only 8. The barges were placed on a sort of bridge that stretched from the conning tower, through the forward funnel to the after funnel. And last but not least, this class also had a novelty in armouring - protected funnels. Like any new design, it also had shortcomings: the side turrets could indeed fire on opposite sides (starboard to port and vice versa), but this was only possible in an emergency due to damage to the superstructure and was not commonly used
the side turrets had their ammunition and ammunition stores extended to the side of the ship, which made them vulnerable in combat, and they were also close to large heat sources (boilers)
the rear upper turret had a limited firing angle - due to damage to the sight holes on the lower turret it could not fire at an angle of about 30° aft (aft of the ship)
the "bridge" or raised deck, on which the boats were placed, had the disadvantage that it was connected to the conning tower and in case of damage to the deck in battle, it could damage not only the conning tower but also the side turrets in case of a fall on the main deck
this ship was equipped with a central fire control system, but after the failures that accompanied this equipment during the ship's trials it was then dismantled
Another change from its predecessors was the reduction in the number of 102 mm guns to 16 and the fact that they were no longer mounted on the roofs of the main artillery turrets.
The guns and crew at such a location were found to be very vulnerable and ammunition supply was also very problematic.


Služba
The flagship Home Fleet was put into service early. She was in this position until May 1912 when she was reassigned to the 1st Battle Squadron, where she remained until June 1916. She was then reassigned to the 4th Battle Squadron. On 18 March 1915, the submarine U29 attempted to attack her, unsuccessfully. On the night of 22-23 April 1916 she collided with the steamer Needvaal, suffering very little damage. In the Battle of Skagerrak she fired 48 shots and scored several hits on SMS Lützow. She herself was not damaged. After the war she was reassigned to reserve and sold for scrap in September 1922.
