Ise was a Japanese battleship built in 1915, launched in November 1916, and commissioned into the Imperial Japanese Navy in December 1917. The ship was 219 m long, 33.8 m wide, and had a full displacement of 38,800 tons. The maximum speed of the battleship Ise was around 21-23 knots. The main armament at the time of launch was 12 356 mm guns in six turrets with two guns each, and the secondary armament was primarily 16 140 mm guns.
Ise was the first battleship of the same name, Ise. During World War I, it did not undergo any major modernizations, but in the years 1921-1928 and 1934-1937 it underwent major reconstructions. First of all, the armor was significantly reinforced, catapults for seaplanes and anti-aircraft artillery were added. The entire engine room was also modernized. From September 1942, Ise underwent another modernization, which made it a hybrid ship: battleship-aircraft carrier. In order to create a flight deck for aircraft, two aft gun turrets were dismantled. However, the idea turned out to be a complete failure, and Ise failed as a battleship, never becoming a proper aircraft carrier. During World War II, Ise fought in the Aleutian Islands in May 1942, and in October took part in the Battle of Leyte, where it was damaged. In February 1945, she was damaged again at the base in Kure by an attack by American carrier-based aircraft. In 1946, the ship was scrapped.
