India's Quantum Sensing Tech to Detect Submarines at 200m Depths.
India is making significant advances in defense technology with the development of indigenous quantum sensing capabilities poised to detect submarines at depths of 100-200 meters. Announced by DRDO Chief Dr. Samir V. Kamat on October 24, 2025, this technology employs ultra-sensitive atomic magnetometers integrated on UAVs and aircraft to detect subtle disturbances in the Earth’s magnetic field caused by submarines. This breakthrough will augment India’s anti-submarine warfare (ASW) capabilities by enabling passive detection methods that …
