context_page_description: The King Edward VII class was a class of eight pre-dreadnought battleships launched by the Royal Navy between 1903 and 1905. The class comprised King Edward VII, the lead ship, Commonwealth, Hindustan, Britannia, Dominion, New Zealand, Africa, and Hibernia. They marked the first major development of the basic pre-dreadnought type that had been developed with the Majestic type of the mid-1890s, all of which had been designed by the Director of Naval Construction, William Henry White, with the primary innovation being the adoption of a heavy secondary battery of four 9.2-inch guns to supplement the standard main battery of four 12 in guns. The King Edward VIIs were among the last pre-dreadnoughts built for the Royal Navy before the construction and launch of the revolutionary battleship HMS Dreadnought in 1906, which immediately rendered them obsolescent.
  The ships served with the Atlantic Fleet from 1905 to 1907, when they were transferred to the Channel Fleet, though this service lasted only until 1908–1909, when they were reassigned to the Home Fleet.
context_section_description: The ships of the King Edward VII class underwent a series of modifications over the courses of their careers. In 1907, King Edward VII had some of her 12-pounder guns temporarily relocated to the main battery turret roofs, but this was found to be unsatisfactory and they reverted to their original locations that same year. Between 1907 and 1908, she and Commonwealth, Dominion, Hindustan, and New Zealand had their bridge-mounted 3-pounders removed. They also received search lights in various positions, including the 9.2-inch turret roofs and the bridge wings. Funnel identification bands were added to all eight ships as well. Hibernia and Hindustan received rangefinders on their aft superstructure in 1911–1912, and most of the ships had further alterations to their search lights. Africa had experimental aircraft launching ramps installed on her bow in 1912 for flight tests, though the equipment was later transferred to Hibernia that year, from which it was removed altogether.
  After the start of the First World War in August 1914, Zealandia (ex-New Zealand) gave one of her 12-pounders to arm a Q-ship, receiving a pair of 3-pounders in its place. During a refit in that period, Dominion's bridge was enlarged. The 6-inch battery was removed from all of the ships of the class between 1916 and April 1917, with each ship having four of the guns re-mounted a deck higher in open pivot mounts in place of the 12-pounder guns that had been located there, where they were less affected by heavy seas, and thus, were more usable weapons. Additional search lights were installed during this period as well.
  In 1918, Zealandia and Commonwealth were heavily modernised for use as gunnery training ships. Their pole masts were replaced with heavy tripod masts that were capable of supporting the latest fire control directors and rangefinders. Their remaining 12-pounder guns were removed and a pair of 3 in (76 mm) anti-aircraft guns were added on the aft superstructure. Commonwealth received anti-torpedo bulges, though Zealandia did not. Commonwealth received dazzle camouflage, and it has been reported that Zealandia was similarly painted, but according to the naval historian R. A. Burt, the "lack of official and photographic evidence rules this out."
