Three linked documentaries make the case that World War II was decided as much in factories as on battlefields. The first follows the USS Enterprise and the rise of carrier-based aircraft after Pearl Harbor, tracing how naval warfare changed once planes could launch from ships. The second traces the Rolls-Royce Merlin engine, the power plant behind the Spitfire, Hurricane, Lancaster, and Wellington, and argues it was as decisive to the Battle of Britain as any pilot. The third turns to Skoda's Czech arms factory, one of Europe's largest, and follows how it doubled as cover for sabotage, espionage, and efforts to smuggle Jews out of occupied Europe during the 1930s and into the war. Archival footage, period photographs, and narration carry each segment, moving between production lines, cockpits, and factory floors rather than generals and battle maps. Together the three episodes build an argument about industrial capacity, out-producing the Axis, as the quiet engine behind Allied victory.
