The Electronic Shield That Changed Warfare
How 80-year-old proximity fuse technology is saving lives in Ukraine and defeating modern threats From London's defense against V-1 flying bombs to Ukraine's modern battlefield, radar-guided proximity fuses continue revolutionizing military effectiveness By Science Correspondent Published September 26, 2025 On August 28, 1944, German technical officers at Flak Regiment 155W stared at impossible mathematics: their V-1 flying bombs were being destroyed at an 82% interception rate by British coastal defenses.
