Why it matters: This initiative helps Tokyo counter rising naval threats while cutting personnel costs through uncrewed systems.
- The quantum magnetic sensors use atomic properties to detect tiny magnetic field changes caused by submarines China.
- The sensors will mount on surface drones launched from warships South China Morning Post.
