What were the design flaws of the German battleship Bismarck? What was its ultimate fate?

The German public had hopes for Hitler when he came to power in 1933. While pursuing a hard-line foreign policy, Hitler was internally anti-Semitic and engaged in brutal racial oppression. But at the same time, Hitler carried out effective reforms to Germany's industry, education, scientific research, and health care, and Germany's national power rose rapidly and restoratively. French Marshal Foch had said that the 1919 Paris Peace Treaty was a 20-year armistice, and that punishment of Germany would provoke Germany to even more insane acts of war. True to form, Hitler ordered rearmament and a huge program of military expansion began. The German army had been destroyed after World War I. The so-called expansion was a complete rebuilding of a German chariot, with no scruples, and advanced ideas and technology were widely utilized. German Marshal Reiser began his leadership of the navy, preferring large surface warships to his successor's obsession with submarines. Hitler received tacit approval from Britain to build a navy with a total displacement equal to one-third of Britain's. It was in this context that the construction of the Bismarck began, and its advanced design made it famous among the European powers long before it was built. HMS Bismarck, full load displacement of 50,000 tons, speed up to 30 knots, protective armor accounted for the ship's mass of 42/100. powerful firepower, mainly eight 381mm caliber main guns, with a large number of secondary guns and anti-aircraft guns, advanced early warning and observation equipment, anti-torpedo design is good and effective, officers and men 2250 people. Such indicators in Europe is absolutely far ahead of the British "George V" class displacement of 38,000 tons, the main gun caliber 356mm, Italy's battleship displacement up to 40,000 tons, the main gun caliber of 406mm, but the protective armor is too fragile, difficult to resist torpedo attacks, France and the Soviet Union is still not built at the outbreak of the Great War. The French and Soviets were still not built at the outbreak of the Great War. So it seems that the Bismarck was good enough for Europe, perhaps the only drawback was that it was not powerful enough, the American Iowa had nine 406mm main guns and a displacement of 50,000 tons, and the Japanese Yamato, with nine 460mm main guns and a displacement of 64,000 tons. But they all had the tragedy that the masters of the seas were already aircraft carriers. in 1939, the ship was commissioned and deployed at Wilhelmshaven, a military port that the Empire had spent 100 years operating. in 1940, Bismarck undertook the last and most famous sortie of her life, striking out into the North Atlantic with the heavy cruiser Prinz Eugen to disrupt the British line of maritime communication, code-named Exercise Rhine. The British sent the battlecruiser HMS Hood and the battleship Prince of Wales to meet the enemy, and it looked like they had the upper hand, but they didn't. Peiseler took the initiative to meet the enemy by flanking, despite the large enemy surface, but all nine main guns could be used, while the British met the enemy in the forward direction, 12 main guns, but a single door is not as good as the German, so the two sides were equal in firepower. German observation equipment and artillery played a decisive role, in Peas Marck after 55 flak, that is, 440 rounds of 381mm shells, Hood's ammunition magazine was hit, a big explosion, sinking quickly, the Prince of Wales was also wounded, retreating (1942 was sunk by the Japanese in the Malayan Sea). Bergsmeier took one shot in the front, losing 200 tons of fuel, and her oil trail revealed her whereabouts. The British were furious and sent 42 battleships, including 2 carriers, to surround the ship, but the initial attack was unfavorable, and it was a miracle that Peugeot could continue under such pressure. The British, in hot pursuit, abandoned their attack on Prince Eugen and hit Peismeyer with all their might. Peenmark's position was becoming increasingly difficult, and finally the captain sent a telegram "We will fight to the last bullet!" More than 2,000 men sank with the ship. It is worth mentioning that he has been hit by the British heavy artillery 719 rounds. 1944, the sister ship was sunk in Norway, the German Third Reich's only two battleships will no longer exist, the era of the big ships and huge guns ended, the aircraft carriers dominate the sea.
