2015年3月3日，保羅·艾倫投資的八爪魚號在潛水探測時於菲律賓錫布延海水下深度1,000公尺找到了武藏號的殘骸.In March 2015, Paul Allen and his team of researchers located what appears to be the wreck of Musashi in the Sibuyan Sea using a remotely operated vehicle deployed from the yacht Octopus.^] The ship lies at a depth of around 1,000 metres (3,300 ft).^[

1938年（武藏）的建造。在三菱重工業長崎造船所進行過建造的戰艦當中，「武藏」7萬噸級。

1944年10月，由栗田健男海軍中將率領包括武藏在內的第2艦隊從婆羅洲北部的斯里巴卡旺出發參加雷伊泰灣海戰，企圖攻擊位於雷伊泰灣的盟軍登陸艦隊。1944年10月24日進入菲律賓錫布延海，10時30分遭到美軍航空母艦飛機攻擊。「武藏」號成為美軍飛機主要攻擊目標之一。

「武藏」被第一枚魚雷命中時，相當於400公斤黃色炸藥的爆炸三輪空襲之後，「武藏」號向左傾斜10度，脫離編隊。15時孤立的「武藏」成為空襲的重點，接二連三地被魚雷、炸彈命中。「武藏」總共被19枚魚雷和17顆航空炸彈擊中。19時15分，由於傾斜增大且無法控制，下達棄艦的命令。「武藏」於19時35分傾覆沉沒，沉沒水域位於北緯13度7分，東經122度32分。

Musashi (武蔵^?) was the second ship of the Yamato class of Imperial Japanese Navy World War II battleships. She and her sister ship, Yamato, were the heaviest and most powerfully armed battleships ever constructed, displacing 72,800 tonnes at full load and armed with nine 46 cm (18.1 inch) Type 94 main guns. Neither ship survived the war.

Named after Japan's ancient Musashi Province, the Musashi was commissioned in mid-1942, modified to serve as the flagship of the Combined Fleet, and spent the rest of the year working up. The ship was transferred to Truk in early 1943 and sortied several times that year with the fleet in unsuccessful searches for American forces. She was used to transfer forces and equipment between Japan and various occupied islands several times in 1944.

Yamato hit by a bomb near her forward gun turret in the Sibuyan Sea, 24 October 1944.
