List of famous battleships in the Imperial Japanese Navy


List of famous battleships in the Imperial Japanese Navy

The following is the list of ships of the Imperial Japanese Navy, including ships that entering service in World War II.


Yamato
-class battleship

The Yamato-class battleships (大和型戦艦 Yamato-gata senkan) were battleships of the Imperial Japanese Navy (IJN) constructed and operated during World War II. Displacing 72,000 long tons (73,000 t) at full load, the vessels were the heaviest and most powerfully armed battleships ever constructed. The class carried the largest naval artillery ever fitted to a warship, nine 460-millimetre (18.1 in) naval guns, each capable of firing 1,360 kg (3,000 lb) shells over 42 km (26 mi). Two battleships of the class (Yamato and Musashi) were completed, while a third (Shinano) was converted to an aircraft carrier during construction.

Due to the threat of American submarines and aircraft carriers, both Yamato and Musashi spent the majority of their careers in naval bases at Brunei, Truk, and Kure—deploying on several occasions in response to American raids on Japanese bases—before participating in the Battle of Leyte Gulf in October 1944, as part of Admiral Kurita's Centre Force. Musashi was sunk during the battle by American carrier airplanes. Shinano was sunk ten days after her commissioning in November 1944 by the submarine USS Archerfish, while Yamato was sunk in April 1945 during Operation Ten-Go.

Nagato-class battleship

The Nagato-class battleships (長門型戦艦 Nagato-gata senkan) were a pair of dreadnought battleships built for the Imperial Japanese Navy (IJN) during World War I, although they were not completed until after the end of the war. Nagato, the lead ship of the class, frequently served as a flagship. Both ships carried supplies for the survivors of the Great Kantō earthquake in 1923. They were modernized in 1933–36 with improvements to their armor and machinery and a rebuilt superstructure in the pagoda mast style. Nagato and her sister ship Mutsu briefly participated in the Second Sino-Japanese War in 1937 and Nagato was the flagship of Admiral Isoroku Yamamoto during the attack on Pearl Harbor on 7 December 1941 that began the Pacific War.

The sisters participated in the Battle of Midway in June 1942, although they did not see any combat. Mutsu saw more active service than her sister because she was not a flagship and participated in the Battle of the Eastern Solomons in August before returning to Japan in early 1943. One of Mutsu‍ '​s aft magazines detonated in June, killing 1,121 crew and visitors and destroying the ship. The IJN conducted a perfunctory investigation into the cause of her loss and concluded that it was the work of a disgruntled crewmember. They dispersed the survivors in an attempt to conceal the sinking to keep up morale in Japan. Much of the wreck was salvaged after the war and many artifacts and relics are on display in Japan.


Nagato
spent most of the first two years of the war training in home waters. She was transferred to Truk in mid-1943, but did not see any combat until the Battle of the Philippine Sea in mid-1944 when she was attacked by American aircraft. Nagato did not fire her main armament against enemy vessels until the Battle of Leyte Gulf in October 1944. She was lightly damaged during the battle and returned to Japan the following month for repairs. The IJN was running out of fuel by this time and decided not to fully repair her. Nagato was converted into a floating anti-aircraft platform and assigned to coastal defense duties. After the war, the ship was a target for U.S. nuclear weapon tests during Operation Crossroads in mid-1946. She survived the first test with little damage, but was sunk by the second test.


Fusō
-class battleship

The Fusō-class battleships (扶桑型戦艦 Fusō-gata senkan) were a pair of dreadnought battleships built for the Imperial Japanese Navy (IJN) during World War I. Both patrolled briefly off the coast of China before being placed in reserve at the war's end. In 1922 Yamashiro became the first battleship in the IJN to successfully launch aircraft.
During the 1930s, both ships underwent a series of modernizations and reconstructions. Fusō underwent her modernization in two phases (1930–33, 1937–41), while
Yamashiro
was reconstructed from 1930 to 1935. The modernization increased their armor, replaced and upgraded their machinery, and rebuilt their superstructures into the distinctive pagoda mast style. Despite the expensive reconstructions, both vessels were considered obsolescent by the eve of World War II, and neither saw significant action in the early years of the war. Fusō served as a troop transport in 1943, while Yamashiro was relegated to training duty in the Inland Sea. Both underwent upgrades to their anti-aircraft suite in 1944 before transferring to Singapore in August 1944.


Fusō
and Yamashiro were the only two Japanese battleships at the Battle of Surigao Strait, the southernmost action of the Battle of Leyte Gulf, and both were lost in the early hours of 25 October 1944 to torpedoes and naval gunfire. Some eyewitnesses later claimed that Fusō broke in half, and that both halves remained afloat and burning for an hour, but historian Anthony Tully has made the case that she simply sank after forty minutes of flooding. Six battleships and eight cruisers were lying in wait for Yamashiro; she did not survive the encounter, and Vice-Admiral Shōji Nishimura went down with his ship. Only ten crewmembers from each ship survived.

Ise-class battleship

The Ise-class battleships (伊勢型戦艦 Ise-gata senkan) were a pair of dreadnought battleships built for the Imperial Japanese Navy (IJN) during World War I. Originally intended to be repeats of the preceding Fusō class, they were redesigned before construction began. Both ships carried supplies for the survivors of the
Great Kantō earthquake
in 1923. They were modernized in 1934–37 with improvements to their armour and machinery and a rebuilt superstructure in the pagoda mast style. Afterwards they played a minor role in the Second Sino-Japanese War.


Despite the expensive reconstructions, both vessels were considered obsolete by the eve of the Pacific War, and neither saw significant action in the early years of the war. Following the loss of most of the IJN's large aircraft carriers during the Battle of Midway in mid-1942, they were rebuilt with a flight deck replacing the rear pair of gun turrets to give them the ability to operate an air group of floatplanes. A lack of aircraft and qualified pilots, however, meant that they never actually operated their aircraft in combat. While awaiting their air group the sister ships were sometimes used to ferry troops and material to Japanese bases. They participated in the Battle of Cape Engaño in late 1944, where they decoyed the American carrier fleet supporting the invasion of Leyte away from the landing beaches. Afterwards both ships were transferred to Southeast Asia; in early 1945 they participated in Operation Kita, where they transported petrol and other strategic materials to Japan. The sisters were then reduced to reserve until they were sunk during American airstrikes in July. After the war they were scrapped in 1946–47.

Kongō-class battlecruiser

The Kongou-class battlecruiser (金剛型巡洋戦艦 Kongō-gata jun'yōsenkan) was a class of four battlecruisers built for the Imperial Japanese Navy (IJN) immediately before World War I. Designed by British naval architect George Thurston, the lead ship of the class was the last Japanese capital ship constructed outside Japan, by Vickers.
During the late 1920s, all but Hiei were reconstructed and reclassified as battleships. After the signing of the London Naval Treaty in 1930, Hiei was reconfigured as a training ship to avoid being scrapped. Following Japan's withdrawal from the London Naval Treaty, all four underwent a massive second reconstruction in the late 1930s. Following the completion of these modifications, which increased top speeds to over 30 knots (56 km/h; 35 mph), all four were reclassified as fast battleships.

The Kongō-class battleships were the most active capital ships of the Japanese Navy during World War II, participating in most major engagements of the war. Hiei and Kirishima acted as escorts during the attack on Pearl Harbor, while Kongō and Haruna supported the invasion of Singapore. All four participated in the battles of Midway and Guadalcanal. Hiei and Kirishima were both lost during the Naval Battle of Guadalcanal in November 1942, while Haruna and Kongō jointly bombarded Henderson Field on Guadalcanal. The two remaining Kongō-class battleships spent most of 1943 shuttling between Japanese naval bases before participating in the major naval campaigns of 1944. Haruna and Kongō engaged American surface vessels during the Battle of Leyte Gulf. Kongō was torpedoed by USS Sealion in November 1944, while Haruna was sunk at her moorings by air attack in Kure Naval Base in late July 1945 and subsequently scrapped.
