Nazi Germany's wartime engineering program gets a full survey here, from the 1,350-ton Gustav railway gun and the 190-ton Maus super-heavy tank to the ME262 jet fighter and the V2 rocket. The film lays out how Hitler pushed for technological breakthroughs he believed could reverse Germany's fortunes, and follows the projects through design, testing, and the underground factories built to hide them from Allied bombers. It also tracks what actually killed these programs: fuel shortages, raw material bottlenecks, Allied air raids on production sites, and Hitler's own interference in engineering decisions. Archival footage and photographs of the hardware are paired with expository narration that places each weapon in the context of Germany's collapsing war economy. The final stretch traces the postwar afterlife of this research, as captured V2 designs and jet propulsion work fed directly into American and Soviet rocketry and aircraft programs. It is a survey of ambition outrunning logistics, built and lost within a few frantic years.
