The Bismarck sails in May 1941 as the largest, most heavily armored warship in Europe, tasked with breaking into the Atlantic to sink convoys feeding Britain. This film tracks the Royal Navy's response, from the disastrous encounter with HMS Hood, sunk in minutes at the Denmark Strait, to the desperate hunt across the North Atlantic that follows. A single torpedo launched from an obsolete Swordfish biplane strikes the Bismarck's rudder, jamming her steering and turning Europe's most advanced battleship into a stationary target for the converging British Home Fleet. Using archival footage, ship diagrams, and expert analysis, the film examines the engineering and design choices behind Germany's battleship program and asks why a vessel built to dominate the seas proved so vulnerable in the end. It weighs armor, firepower, and speed against the tactical realities of 1940s naval warfare, and lays out how a chance hit from outdated technology decided the fate of the era's most feared warship.
