Modern Marvels: WWII (Season 1)

Modern Marvels: WWII (2026) is an American documentary series you can watch online on iFILM. The latest installment of the long-running Modern Marvels franchise skips the sweeping battle narratives and goes straight to the hardware — the machines, weapons and engineering breakthroughs that actually determined outcomes on the ground.

Each episode focuses on a single innovation, from cipher devices to jet propulsion, and traces the line from wartime necessity to the technology still in use today. A useful watch for anyone who wants to understand the conflict through what was built, not just what happened. Stream Modern Marvels: WWII online on iFILM.
