The LORAN Secret: How 100 kHz Radio Pulses Navigated 75,000 Allied Ships Without Satellites

Описание: During World War II, the Allies faced a critical navigation challenge: guiding ships and aircraft across vast oceans without satellites or reliable radar coverage. The solution was LORAN (Long Range Navigation), a groundbreaking radio warfare system based on precisely timed 100 kHz radio pulses.
Developed by the U.S. Navy and MIT’s Radiation Laboratory and first deployed in 1942, LORAN used synchronized transmitter stations to measure time differences between signals, allowing navigators to determine their position within a few miles. By the end of the war, the system had guided more than 75,000 Allied ships and aircraft, supporting convoy protection, strategic bombing missions, and amphibious landings.
This episode explains the engineering principles, timing synchronization challenges, and wartime construction of LORAN stations under combat conditions. LORAN’s core concepts later influenced modern navigation systems and resilient alternatives to GPS still studied in military engineering and engineering education today.
