Yamato - Great Japanese Ship

peret

Yamato, named after the ancient Japanese Yamato Province, was a battleship of the Imperial Japanese Navy. She was the first built (the lead ship) of the Yamato class. She and her sister ship Musashi were the largest, heaviest battleships ever constructed, weighing 65,027 tons. She carried the heaviest armament ever fitted to a battleship: nine 460 mm (18.1 inch) guns.



The Yamato class were designed in the post Washington Naval Treaty period. The treaty had been extended by the London Naval Treaty of 1930 which limited the signatories to no battleship production before 1937梩he Japanese withdrew from the Treaty at the Second London conference of 1936. Design work on the class began in 1934 and after modifications the design for a 68,000 ton vessel was accepted in March 1937. The Yamato was built in intense secrecy at a specially prepared dock to hide her construction at Kure Naval Dockyards beginning on 4 November 1937. She was launched on 8 August 1940 and commissioned on 16 December 1941. Originally it was intended that five ships of this class would be built, but the third ship of the class, Shinano, was converted to an aircraft carrier during construction after the defeat at the Battle of Midway, the un-named "Hull Number 111" was scrapped in 1943 when roughly 30% complete, and "Hull Number 797", proposed in the 1942 5th Supplementary Program, was never ordered. Plans for a "Super Yamato" class, with 50.8 cm (20 inch) guns, provisionally designated as "Hull Number 798" and "Hull Number 799", were abandoned in 1942.

The class was designed to be superior to any ship that the United States was likely to produce. The 46 cm (18.1-inch) main guns were selected over 40.6 cm (16 inch) because the width of the Panama Canal would make it impracticable for the U.S. Navy to construct a battleship with the same caliber guns without severe design restrictions or an inadequate defensive arrangement. To further confuse the intelligence agencies of other countries, her main guns were officially named as 40.6 cm Special, and civilians were never notified of the true nature of the guns. Their budgets were also scattered among various projects so that the huge total costs would not be immediately noticeable.

At the Kure Navy Yard where she was built, the construction dock was deepened, the gantry crane capacity was increased to 100 metric tonnes, and part of the dock was roofed over to prevent observation of work.

Arc welding, a relatively new procedure at that time, was used extensively during construction. The lower side-belt armor was used as a strength member of the hull structure. The undulating line of the main deck forward saved structural weight without reducing hull girder strength. Tests of models in a model basin led to the adoption of a semitransom stern and a bulbous bow, which reduced hull resistance by 8%. The ship had one single large rudder (at frame 231), which gave it a small (for a ship of that size) turning circle of 640 meters. By comparison the US Iowa class fast battleship had one of over 800 m. There was also a smaller auxiliary rudder installed (at frame 219) which was virtually useless. The steam turbine power plant was a relatively low powered design (25 kgf/cm² (2.5 MPa), 325 癈), and as such, their fuel usage rate was very high. This is a primary reason why they were not used during the Solomon Islands campaign and other mid-war operations. There were a total of 1147 watertight compartments in the ship.

Yamato was the flagship of Admiral Isoroku Yamamoto from 12 February 1942, replacing Nagato. She took part in the Midway operation in June, 1942, but took no active part in the Battle of Midway. She remained the flagship for 364 days until February 11, 1943, when the flag was transferred to her sister ship Musashi. From 29 August 1942 through to 8 May 1943, she spent all of her time at Truk, being underway for only 1 day during this entire time. In May 1943, she returned to Kure where the two wing 15.5 cm turrets were removed and replaced by 25 mm machine guns, and Type-22 surface search radars were added. She returned to Truk on 25 December 1943, and on the way there, she was damaged by a torpedo from the submarine USS Skate, and was not fully repaired until April 1944. During these repairs, additional 12.7 cm anti-aircraft guns were installed in the place of the 15.5 cm turrets removed in May, and additional 25 mm anti-aircraft guns were added.

She returned to the conflict and joined the Japanese fleet in the Battle of the Philippine Sea in June 1944. In October, she participated in the Battles of Leyte Gulf and Samar, during which she first fired her main guns in action, and she received two bomb hits from aircraft which did little damage. She returned home in November and her anti-aircraft capability was again upgraded over the winter. She was attacked in the Inland Sea on March 19, 1945 by carrier aircraft from Task Force 58 as they attacked Kure. She suffered little damage during the engagement.

Her final mission was as part of Operation Ten-Go following the invasion of Okinawa on 1 April 1945. She was sent on a suicide mission (commanded by Admiral Seiichi Ito) to attack the US fleet supporting the US troops landing on the west of the island. On 6 April Yamato and her escorts, the light cruiser Yahagi and 8 destroyers, left port at Tokuyama. They were sighted on 7 April by American submarines as they exited the Inland Sea southwards. The U.S. Navy launched 386 aircraft to intercept the task force, and the planes engaged the ships starting at 12:30 that afternoon. Yamato took 8 bomb and 10 torpedo hits before, at about 14:23, she capsized to port and her aft magazines detonated. She sank while still some 200 km from Okinawa. Of her crew 2,475 were lost, and the 269 survivors were picked up by the escorting destroyers. Some reports claim that a number of survivors were machine-gunned in the water by U.S. aircraft.[1] However, other Japanese survivors reported that U.S. aircraft temporarily halted their attacks on the Japanese destroyers during the time that the destroyers were busy picking up survivors from the water.

The wreckage lies in around 300 meters of water and was surveyed in 1985 and 1999.

aku ader ngk nat geo nyer documentary about this ship ler.
  sayang..never dpt tenggelam kan kapal perang yg lain ler.

timakasey . aku memang dari kecik slalu dengar kawan aku kat sekolah suka nak cakap pasal Yamato la, Musashi la,  ni dua2 battleship jepun kuat giler.


tak silap, tahun lepas kat jepun keluar filem wayang tentang kapal Yamato ni...

Memang sayang sebab era perang dunia kedua bukan perang antara kapal perang sebaliknya perang udara,
jadi sesiapa mempunyai kekuatan udara yang kuat merekalah yang menguasai udara, jepun pada peringkat awal
mereka dapat menguasai udara kerana kehebatan pesawat zero mereka tetapi apabila pihak berikat telah mengeluarkan
pesawat yang tidak kurang hebat juga seperti hellcat semasa penwanan rabaul dan perang kepulauan truk,
jadi pembinaan kapal sebesar yamato tidak memberi erti kepada tentera jepun, sebaliknya bilangan kapal
pembawa pesawat  yang besar mampu memberi kemenangan kepada sesuatu pihak,

sebab kapal Carrier jepun banyak tenggelam jadi kekuatan udara jepun tak kuat di pasifik dan pengeluaran Kapal terbang Zero terjejas banyak kilang dikawasan jajahan seperti di manchuria di bom oleh tentera berikat

kapal carrier jepun banyak tenggelam semasa perang midway, itulah salah satu impak kepada jepun,
selepas tu jepun dah mula goyang dan tak kuat lagi

mmg ler kt midway admiral jepun terbuat mistake ler.
  that time jepun still rase proud pasai dpt bom hawaii ler.
and i agree that aircraft carrier mmg lebih penting dr battleship ler.

Tentera Laut Jepun masa WW2 agak ironi...mereka merupakan antara pelopor penggunaan carrier (selain US dan UK). tetapi kebanyakan pegawai atasan navy mereka tidak percayakan kapal yang berat kurang 50,000 tan dan membawa persenjataan dibawah 16 inci...Malah Vice Admiral Nagumo yang mengetuai armada carrier Jepun sehingga Midway masih berjiwa 'battleship'.

kalau Yamato diiringi Oleh kapal Pengangkut Jepun kalau tidak karam mungkin nasib berubah

fakta menarik tentang YAMATO

Sejarah pengunaan minyak biodiesel

The Navy, for instance, conducted extensive experimentation on the production of diesel fuel from coconut oil, birch bark, pine needles, and orange peel. When the battleship Yamato made its famous suicide run to Okinawa in April 1945, it was powered entirely by edible refined soybean oil. Sweet potatoes, meanwhile, became a valuable source of aviation fuel.

Amazing! More information about biodiesel is available here:

Yamato's Final Voyage



On her last morning, before the first American planes intercepted her, Yamato would have appeared indestructible. After all, she was the heaviest and most powerful battleship ever built, carrying the most formidable guns ever mounted at sea. This photograph was taken in December 1941, shortly after the Yamato first took to the sea.



Cloud cover precluded accurate firing of the battleship's guns. Almost all of the nearly 400 American fighters and bombers sent to engage Yamato made it into position above her and soon began to strafe the battleship with bullets and drop 1,000-pound bombs. Here, an aircraft's overhead view of its target. This particular image was taken during an earlier battle with American carrier aircraft on October 24, 1944 as Yamato transited the Sibuyan Sea.



Torpedoes explode against Yamato's port side as she turns to avoid the onslaught from bombers.



While the Americans' 1,000-pound bombs held fearsome destructive power, as seen in this one exploding off Yamato's port bow, it was their air-launched torpedoes that ultimately led to the supership's demise. American aviators received orders to drop their torpedoes such that they would penetrate Yamato below the waterline near her bow and stern where her armor was thinnest. They were also instructed to concentrate their torpedoes on just one of Yamato's sides, an approach most likely to cause flooding and eventual sinking. Note the fire in one of the ship's aft turrets.



Eight Japanese destroyers and one cruiser, the Yahagi, tried to assist Yamato in fending off her attackers. Here, the Yahagi fires its six-inch guns. By the end of the battle, Yahagi and all eight destroyers were lost.



After a dozen torpedo hits, even the Yamato's 1,000 watertight compartments couldn't save her, and her lower decks rapidly began to flood. A Curtiss Helldiver bomber like the one seen at right photographed the destruction. At this point, after just a few hours of battle, most of the American pilots returned to their carriers, knowing Yamato's injuries were fatal. In all, Yamato took 12 bomb and seven torpedo hits within two hours of battle.



An astounding series of explosions onboard Yamato produced the mushroom cloud seen here shortly before she sank. Yamato settled on the seafloor 1,200 feet down and about 50 miles southwest of Kyushu, Japan. Experts believe that a fire raging in the battleship's aft secondary magazine caused tons of ammunition to ignite almost simultaneously, producing the blasts that tore the ship in half and sank her. These blasts were perhaps the largest ever to occur at sea.



One of the final photographs of the supership shows her severely damaged hull burning just prior to disappearing beneath the waves. When Yamato sank, marking the last Japanese naval action of the war, she took 2,747 men with her ll but 269 of her crew. Surrounding Japanese ships lost an additional 1,167 men. Only 10 American aircraft went down in the battle, with the loss of just 12 men.

Battleship Yamato (dan Musashi) merupakan ironi kepada tentera laut imperial Jepun. Mereka merupakan antara pioneer penggunaan aircraft carrier...tapi masih diketuai laksamana yang berpaksikan battleship...
