HMS Ark Royal entered service in 1938 as a radical departure from earlier carrier designs, and this film traces the engineering decisions that made her both formidable and, in the end, vulnerable. It covers her construction challenges, her role hunting the Bismarck, and her running battles against the Luftwaffe and U-boats in the Mediterranean and Atlantic, using archival photographs, ship diagrams, and expert interviews to explain why Hitler's propaganda machine reportedly claimed to have sunk her multiple times before a German submarine finally did in November 1941. The documentary walks through her armored flight deck, hangar layout, and aircraft complement to show how carrier design was still being worked out in real time during the interwar years and the war's early battles. Historians weigh in on her tactical importance and the crew's experience aboard a ship that became, briefly, the most famous target in the Kriegsmarine's sights. It is a straightforward technical and operational history rather than a dramatized account.
