One of the largest carriers of WWII, Shinano was originally planned to be the third installment of Yamato class battleships. The construction of this monstrous vessel was started soon after the Japanese defeat at Midway and was completed on Nov. 19, 1944. Its overall length stretched to 266m and it displaced 62,000 tons. It was well protected with heavily armored sides, inherited from Yamato, and a reinforced flight deck able to withstand the direct blast of a 500kg bomb. On its way to be fitted out however, it was spotted and torpedoed by an American submarine, later capsizing off the shores of Shionomisaki.
