Haruna served the Imperial Japanese Navy (IJN) throughout World War 1 (1914-1918) and World War 2 (1939-1945). She was designed with the assistance of the British and formed the forth ship of the four-strong Kongo-class battlecruiser group. These vessels were commissioned from 1913 to 1915 and managed healthily long service careers spanning from 1913 until 1945. By the end of their time at sea, all but one of the class survived war and this sole example was scrapped after being sunk at her moorings during World War 2. As battlecruisers, theses ships were to serve in the capital ship role and carried large caliber main batteries. Unlike battleships, however, armor protection was sacrificed for speed.
Haruna was ordered in 1911 and Kawasaki Shipyards was commissioned for her construction. Her keel was laid down on March 16th, 1912 and she was launched on December 14th, 1913. The vessel's official commissioning came on April 19th, 1915. Haruna held a displacement value of 36,600 tons (long) and measured 728.3 feet long with a beam of 101.7 feet and a draught of 31.9 feet. Her propulsion machinery constituted 36 Yarrow boilers helping to develop 64,000 horsepower to four shafts underneath the stern. Maximum speed in ideal conditions reached 26 knots. Her profile was consistent with the period, the superstructures amassed around midships and bookended by two main masts with several smoke funnels being featured. A very pointed bow ensured speeds could be maintained in relatively calm seas and onboard space allowed for a crew of 1,360 to be carried. Armor protection included 230mm at the turrets, 200mm at the belt and up to 70mm along the deck.
