October 24, 1944: in the waters of the Philippines, the largest naval battle of the Second World War gets under way. Unsinkable: Japan's Lost Battleship, a 2020 American documentary, tells what happened to Musashi, the secret super battleship Japan sent into that fight.

What is Unsinkable: Japan's Lost Battleship about?

By late 1944 the Japanese navy is staking a great deal on one decisive engagement with the United States, a victory meant to reverse the direction of the Pacific war. At the centre of that plan sails Musashi, a warship built in secrecy and on a scale intended to make it impossible to sink. The documentary sets out the thinking behind the gamble, then follows the battleship into the fighting off the Philippines, where the confidence invested in its size and armour is put to the hardest possible test. The outcome is a matter of historical record: the ship that was supposed to help turn the war went to the bottom of the ocean instead. The film's interest lies in how that came about, and in what the loss says about the limits of a single enormous vessel.

Context & significance

Naval history documentaries tend to work on two levels at once. There is the story of machines, of tonnage, guns and engineering ambition, and there is the story of the decisions that sent those machines and their crews into battle. This film sits squarely in that tradition. Its subject is a ship whose very existence was kept hidden, which gives the account an element of mystery beyond the battle itself, and the word lost in the title points to a vessel that vanished beneath the sea. At around 55 minutes it is a compact watch, suited to viewers who want a clear account of one episode instead of a survey of the whole conflict. The production is from the United States and falls under the documentary, historical and war genres.
