Second World War 1939-1945, ship wreck, battleship The Mutsu was the sister ship of the battleship Nagato. The accident cut France’s capital ship fleet by 1/7th, however, and resulted in the peculiar national humiliation that results when a nation’s namesake ship sinks after hitting a rock (Spain would experience the same heartache a year to the day later, when Espana ran aground and was lost). On 7 January 1943, Mutsu steamed from Truk via Saipan to return to Japan together with the carrier Zuikaku, the heavy cruiser Suzuya and four destroyers.  The barbettes of the turrets were protected by armour 305 mm thick, and the casemates of the 140 mm guns were protected by 25 mm armour plates. Post-war salvage attempts proved to be failures, though Mutsu ’s No. After rendezvousing with the remnants of the striking force on 6 June, about half of the survivors from the sunken aircraft carriers of the 1st Air Fleet were transferred to Mutsu. In 1923 she carried supplies for the survivors of the Great Kantō earthquake. , During a refit in 1924 the fore funnel was rebuilt in a serpentine shape in an unsuccessful effort to prevent smoke interference with the bridge and fire-control systems. Mutsu left Hashirajima for Kure on 13 April, where she prepared to sortie to reinforce the Japanese garrisons in the Aleutian Islands in response to the Battle of the Komandorski Islands. Her displacement increased over 7,000 tonnes (6,900 long tons) to 46,690 tonnes (45,950 long tons) at deep load. 3 turret and the aircraft area just forward of it, just before the explosion. On 8 June 1943, Mutsu was moored at Hashirajima when the magazine of her No. The Navy leadership initially gave serious consideration to raising the wreck and rebuilding her, although these plans were dropped after the divers completed their survey of the ship on 22 July. Accidental explosion within a magazine. Battleship Mutsu Mutsu was the second and last Nagato-class dreadnought battleship built for the Imperial Japanese Navy (IJN) at the end of World War I. They embodied the prestige of the nation, with all of the emotional commitment that implies. On Tuesday 8 June 1943 the Mutsu was moored at the Battleship Division 2 flagship buoy No.2 in the Hashirajima fleet anchorage approximately 3 km (1.9 mi) south-west of the island of Hashirajima and just to the west of Mitsuhima island in the Inland Sea, hosting 113 flying cadets and 40 instructors from the Tsuchiura Naval Air Group on a familiarization tour. , The new 41 cm turrets installed during Mutsu's reconstruction were more heavily armoured than the original ones. , Mutsu, named for Mutsu Province, was laid down at the Yokosuka Naval Arsenal on 1 June 1918 and launched on 31 May 1920.  These 25-millimetre (0.98 in) guns had an effective range of 1,500–3,000 metres (1,600–3,300 yd), and an effective ceiling of 5,500 metres (18,000 ft) at an elevation of 85 degrees. Mutsu served as flagship of Emperor Hirohito during the 1927 naval manoeuvres and fleet review. Her number three turret had begun to smoke, and shortly thereafter a magazine detonated, cutting the ship in half. In consequence, the Courbets were roundly inferior to most of their foreign contemporaries. The sole surviving battleship, Mutsu’s sister ship Nagato, was used as an atomic bomb target at Bikini Atoll in 1947. 843 men died with the ship, and the wreck remains a protected war grave. The rate of fire for the guns was around two rounds per minute. Rumors abounded that Italian frogmen had destroyed the ship as revenge for the transfer, but no proof ever emerged. Their maximum rate of fire was 14 rounds a minute, but their sustained rate of fire was around eight rounds per minute. 3 turret formerly on display at the, A rudder and a section of propeller shaft were on display at the Arashiyama Art Museum until it closed around 1991. , During the Battle of the Eastern Solomons on 27 August, Mutsu, assigned to the support force, fired four shells at enemy reconnaissance aircraft, the first and only time her guns were fired in anger during the war. Most of the wreck was salvaged for pre-nuclear detonation steel research after the war until the 80's. While Mutsu was still fitting out, the American government called a conference in Washington, D.C. late in 1921 to forestall the expensive naval arms race that was developing between the United States, the United Kingdom and the Empire of Japan. Third ship of the Conti di Cavour class dreadnoughts, Leonard da Vinci (named after the famous inventor) entered service in May 1914. The navy dispersed the survivors in an attempt to conceal the sinking in the interest of morale in Japan.  The turrets were protected with an armour thickness of 305 mm on the face, 230–190 mm (9.1–7.5 in) on the sides, and 152–127 mm (6–5 in) on the roof. On the night of August 2, 1916, Leonardo da Vinci exploded and sank during ammunition loading operations. , After the explosion, as the rescue operations commenced, the fleet was alerted and the area was searched for Allied submarines, but no traces were found. Nearby ships were able to rescue 353 survivors from the 1,474 crew members and visitors aboard Mutsu, meaning that 1,121 men were killed in the explosion.  Mutsu was commissioned on 24 October 1921 with Captain Shizen Komaki in command. She went through an extensive modernization in … Hyuga was an Ise-class battleship of the Imperial Japanese Navy. The survivors of Mutsu were dispersed across the fleet and sworn to secrecy; some of the families of the dead were not informed of the cause of the loss until after the war. On August 26, 1922 France struck an uncharted rock reef in Quiberon Bay and quickly began to sink. 1200 lives where lost on that day in 1943.  In addition her turbines were replaced by lighter, more modern, units. That June, one of her aft magazines detonated while she was at anchor, sinking the ship with the loss of 1,121 crew and visitors. , The ship's waterline armour belt was 305 mm (12 in) thick and tapered to a thickness of 100 mm (3.9 in) at its bottom edge; above it was a strake of 229 mm (9 in) armour. , The ship was fitted with a 10-metre (32 ft 10 in) rangefinder in the forward superstructure. Fast, well-armored, and armed with eight 16-inch guns, she was the equal of any battleship in the world during the interwar period.  The turrets aboard the Nagato-class ships were replaced in the mid-1930s using those stored from the unfinished Tosa-class battleships. On June 8, 1943, Mutsu exploded at anchor.  Her crew consisted of 1,333 officers and enlisted men as built and 1,368 in 1935.  Her seaplanes bombed targets in Shanghai on 24 August before she returned to Sasebo the following day. Mass cremations of recovered bodies began almost immediately after the sinking. "In regard to the continued absence of the battleship MUTSU from traffic, Honolulu now state they have some Jap prisoners of war who are definite that MUTSU was torpedoed in Home waters when on passage south and returned to Japan but her magazines blew up on arrival." HMS Vanguard was one of the St. Vincent class, itself one of a series of classes of battleship very similar to HMS Dreadnought. , On 8 June 1943, Mutsu was moored in the Hashirajima fleet anchorage, with 113 flying cadets and 40 instructors from the Tsuchiura Naval Air Group aboard for familiarisation. These are the 5 worst battelship disasters of all time. More than 1100 members of her crew died in the explosion and subsequent sinking. The 25 mm AA guns were controlled by a Type 95 director that was also introduced in 1937. The ship had a length of 201.17 meters (660 ft) between perpendiculars and 215.8 meters (708 ft) overall. , Divers were brought into the area to retrieve bodies and to assess the damage to the ship. 3746, a small Nishimura-class search and rescue submarine, explored the wreck on 17 June with a crew of seven officers. While fire in the secure magazines was a very remote possibility, a fire in an area adjacent to the No. Mutsu history: (from Wikipedia) Mutsu (陸奥) named after Mutsu Province, was the Imperial Japanese Navy's second Nagato class battleship, laid down at the Yokosuka Naval Arsenal on June 1, 1918, launched on May 31, 1920, and completed on Nov 22, 1921. That has a lot to do with why it has spent the last 95 years rusting on the seafloor just outside the mouth of Pensacola Bay. They arrived at Truk on 17 August.  When Mutsu conducted her post-reconstruction trials, she reached a speed of 24.98 knots (46.3 km/h; 28.7 mph) with 82,300 shp (61,400 kW). An investigation concluded that the most likely cause was a minor fire in a small magazine, possibly caused by overheating from unsafe ventilation practice. As it turned out, the ship took on water unevenly and capsized. Everything changed on July 9, 1917. No enemy hardly meant no effort to find fault, however. The main deck armour was 69 mm (2.7 in) while the lower deck was 75 mm (3 in) thick. The building time was approx 6 weeks. Here is the IJN MUTSU 1943 from the Aoshima (New mold) in 1:700 scale. Mutsu was the second and last Nagato-class dreadnought battleship built for the Imperial Japanese Navy (IJN) at the end of World War I. The ship began to sink immediately. During October Mutsu off-loaded surplus fuel oil to the fleet oil tanker Kenyo Maru, allowing the tanker to refuel other ships involved in Guadalcanal operations. , At the time of the explosion, Mutsu's magazine contained some 16-inch Type 3 "Sanshikidan" incendiary shrapnel anti-aircraft shells, which had caused a fire at the Sagami arsenal several years earlier due to improper storage. She was refitted in early 1941 in preparation for war; as part of this work, she was fitted with external degaussing coils and additional armour for her barbettes. , Mutsu's anti-aircraft armament was upgraded during 1932. 1 Basic 2 Upgrade 3 Second Upgrade 4 Quotes 4.1 Hourly Notifications (Kai) 4.2 Seasonal Quotes 5 Notes 5.1 Nagato-class Kai Ni Special Cut-In 5.1.1 Activation Requirements 5.1.2 Cut-In Behavior 6 Character 6.1 Appearance 6.2 Personality 7 Trivia 8 CG 9 See Also Mutsu Nagato Class Battleship Statistics HP 80 (82) Firepower 82 (99) Armor 75 (89) Torpedo 0 Evasion 24 (49) AA 31 (89) Aircraft … The ship was broken in two by the explosion with the 535 foot forward section sinking immediately and the 147 foot aft section sinking 14 hours later.  The crew totalled around 1,475 men in 1942. Funding for the ship had partly come from donations from schoolchildren. HIJMS Mustu, second ship of the Nagato class, was one of the world’s finest battleships when she entered service in the early 1920s. When commissioned in 1921, she and her sister-ship were the first battleships in the world with 16 inch (406.4 mm) guns and were considered the Japanese navy equivalents of the British Navy’s Queen Elizabeth class. The U.S.S.  July 1944: The oiled-starved IJN cut a hole in the bottom of MUTSU’s hulk and pump out 580-tons of fuel oil for use by their ships in Operation Take ("Bamboo"). They did not merely represent national power; they were the physical manifestations of that power. 3 turret exploded at 12:13, cutting the ship in half.  Following the loss of all four carriers on 4 June, Yamamoto attempted to lure the American forces west to within range of the Japanese air groups at Wake Island, and into a night engagement with his surface forces, but the American forces withdrew and Mutsu saw no action. Mutsu, named for Mutsu Province, was laid down at the Yokosuka Naval Arsenal on 1 June 1918 and launched on 31 May 1920. To avert the potential damage to morale from the loss of a battleship, Mutsu ' s loss was declared a state secret.  When firing at surface targets, the guns had a range of 14,700 metres (16,100 yd); they had a maximum ceiling of 9,440 metres (30,970 ft) at their maximum elevation of +90 degrees. In addition to the 140 mm gun donated to the Yasukuni Shrine, now on display at the Yasukuni Museum, the following items recovered over the years can be viewed at various museums and memorials in Japan: According to Skwiot, two single mounts were added in 1932–1934 and another pair, mounted near the aft funnel, were added in 1934. 1 turret. One of the 140 mm casemate guns was raised in 1963 and donated to the Yasukuni Shrine. According to historian Mark Stille, the twin and triple mounts "lacked sufficient speed in train or elevation; the gun sights were unable to handle fast targets; the gun exhibited excessive vibration; the magazine was too small, and, finally, the gun produced excessive muzzle blast".  Following her return to Truk on 2 September, a group of skilled AA gunnery officers and men were detached to serve as instructors to ground-based naval anti-aircraft gunners stationed in Rabaul. Last week while diving Oshima Island the topic of the Mutsu came up and now several of my dive buddie and I are planning a couple dives to the wreck this summer/spring. Other than participating in the Battle of Midway and the Battle of the Eastern Solomons in 1942, where she did not see any significant combat, Mutsu spent most of the first year of the Pacific War in training. Battleships were enormous investments of national treasure. The Mutsu sunk as a result of an internal explosion in 1943. Contributor: C. Peter Chen ww2dbase Mutsu was the second of two Nagato-class battleships of the Japanese Navy; her construction was the responsibility of naval architect Commander Hiraga Yuzuru. The Washington Naval Conference convened on 12 November and the Americans proposed to scrap virtually every capital ship under construction or being fitted out by the participating nations. France was the fourth ship of the Courbet class, the French navy’s first effort at dreadnought battleships. She quickly capsized, taking 248 officers and men with her. It was named after the province. On 20 August, while sailing from Truk to rendezvous with the main body of Vice Admiral Chūichi Nagumo's 3rd Fleet, Mutsu, the heavy cruiser Atago, and escorting destroyers unsuccessfully attempted to locate the escort carrier USS Long Island in response to a flying boat detecting the American ship.  The armour over the machinery and magazines was increased by 38 mm on the upper deck and 25 mm on the upper armoured deck. I think it’s because Mutsu sank where she did, at a remote location within the home waters, and was completely submerged, that she was left alone when the war ended and no effort was made to raise and scrap her. It was deemed too expensive to fully salvage after some work in the 70's I believe. Vanguard served with the Grand Fleet for most of the war, surviving Jutland and several other less consequential actions. On 29 March 1929, the ship was assigned to Battleship Division 3, together with three light cruisers.
