Japanese battleship Katori

Katori (香取 (戦艦)) was the lead ship of the two pre-dreadnought battleships built in the first decade of the 20th Century, the last to be built by British shipyards for the Imperial Japanese Navy (IJN). Ordered just before the start of the Russo-Japanese War of 1904–05, the ship was completed a year after its end. She saw no combat during World War I, although the ship was present when Japan joined the Siberian Intervention in 1918. Katori was disarmed and scrapped in 1923–25 in accordance with the terms of the Washington Naval Treaty of 1922.

Design and description
The Katori-class ships were ordered just before the start of the Russo-Japanese War in 1904 as improved versions of the Royal Navy’s s. Katori was 456 ft long overall and had a beam of 78 ft. She had a full-load draught of 27 ft and normally displaced 15950 LT and had a crew of 864 officers and enlisted men. The ship was powered by two vertical triple-expansion steam engines using steam generated by 20 Niclausse boilers. The engines were rated at 16000 ihp, using forced draught, and were designed to reach a top speed of 18.5 kn. Katori, however, reached a top speed of 19.5 kn from 18500 ihp on her sea trials. She carried a maximum of 2150 LT of coal and 377 LT of fuel oil which was sprayed on the coal to increase their power. This allowed her to steam for 12000 nmi at a speed of 11 kn.

The ship's main battery consisted of four 12-inch guns mounted in two twin-gun turrets, one forward and one aft. The secondary armament consisted of four 10-inch guns mounted in four single-gun turrets positioned on each side of the superstructure. Katori also carried 12 quick-firing (QF) QF 6-inch guns, mounted in casemates on the sides of the hull and in the superstructure. A number of smaller guns were carried for defence against torpedo boats. These included a dozen QF 12-pounder guns and three 47 mm 3-pounder Hotchkiss guns. She was also armed with five submerged 18-inch torpedo tubes, two on each broadside and one in the stern.

Katori's waterline armour belt consisted of Krupp cemented armour and was 3.5 - 9 in thick. The armour of her main gun turrets had a maximum thickness of 9 in and her deck ranged from 2 to 3 in in thickness.

Construction and career
Katori, named for a Shinto shrine in Katori City, was ordered in January 1904 from Vickers. The ship was laid down at their Barrow-in-Furness shipyard on 27 April 1904. She was launched on 4 July 1905, Prince and Princess Arisugawa were on hand for the official launching ceremony. and completed on 20 May 1906. Katori departed Britain on 7 June on her maiden voyage and shakedown cruise and arrived at Yokosuka on 15 August.

In a naval review off Yokosuka on 10 November 1913, she served as the flagship for the Taishō Emperor. Katori occupied the German colony of Saipan, shortly after the start of World War I, on 14 October 1914. Afterward the ship began a refit in 1914 that lasted until late 1916 and was assigned to the 2nd Battleship Squadron upon its completion. During this refit, two 12-pounder anti-aircraft guns were replaced two of the low-angle 12-pounders. She became the flagship of the 5th Battleship Squadron in 1917–18 and served as the flagship for the Japanese commander-in-chief at Nikolayevsk-on-Amur in late 1918 as Japan decided to intervene in the Russian Civil War.

On 3 March 1921, Katori, escorted by Kashima, departed Yokohama bound for Great Britain carrying Crown Prince Hirohito, the first Japanese crown prince to travel abroad. The ships arrived at Portsmouth on 9 May and Hirohito left the ship to tour Europe; he boarded the battleship again in Naples several months later for the voyage home. The ship was disarmed in April 1922, stricken from the Navy List on 20 September 1923 and scrapped at Maizuru Naval Arsensal by 29 January 1925 to comply with the terms of the Washington Naval Treaty.
