the British naval engineer George Thurston and were ordered in 1910 in the Japanese Emergency Naval Expansion Bill after the commissioning of in 1908. These four battlecruisers of the Kongō class were designed to match the naval capabilities of the battlecruisers of the other major naval powers at the time, and they have been called the battlecruiser versions of the British (formerly Turkish) battleship . Their heavy armament of 14-inch naval guns and their armor protection (which took up about 23.3% of their approximately 30,000-ton displacements in 1913) were greatly superior to those of any other Japanese capital ship afloat at the time. The keel of Kongō was laid down at Barrow-in-Furness by Vickers Shipbuilding and Engineering on 17 January 1911. Under Japan's contract with Vickers, the first vessel of the class was constructed in the United Kingdom, with the remainder built in Japan. Kongō was launched on 18 May 1912, and then transferred to the dockyards of Portsmouth, England, where her fitting-out began in mid-1912. All parts used in her construction were manufactured in the U.K. Kongō was completed on 16 April 1913. Siemens-Vickers Scandal In January 1914, a telegram leaked from Siemens' Tokyo office to Reuters along with further reporting by the New York Times and Asahi Shimbun led to an investigation by Japanese authorities which revealed a pattern of bribery and kickbacks by German and English armaments corporations. Siemens had been paying senior Japanese officials a secret 15% kickback, until Vickers had outbid them by offering 25%. Vickers had paid 210,000 yen to Admiral Fuji of the Imperial Japanese Navy procurement in 1911 and 1912, and 40,000 yen to Vice Admiral Kazu, related to obtaining the contract for building Kongō. Kazu was court-martialed in May 1914, fined 400,000 yen and sentenced to 3 years in prison. As a result of the Siemens-Vickers Scandal revolving around the contracts of building Kongō, the government of Prime Minister Yamamoto resigned March 23, 1914. Senior executives of the Mitsui corporation, Japanese partners of Vickers, also resigned. Armament Kongōs main battery consisted of eight heavy-caliber main naval guns in four twin turrets (two forward and two aft). The turrets were noted by the U.S. Office of Naval Intelligence to be "similar to the British 15-inch turrets", with improvements made in flash-tightness. Each of her main guns could fire high explosive or armor-piercing shells at a rate of about two shells per minute.
