The sea of tomorrow might be about as difficult to traverse stealthily as an elephant stomping through a room full of mousetraps thanks to Anduril's Seabed Sentry undersea sensor network that uses AI to autonomously track ocean traffic.

American defense technology company Anduril has rolled out its Copperhead-M – an Autonomous Underwater Vehicle (AUV) that provides uncrewed subs with the punch of a smart torpedo carrying up to 500 lb (227 kg) of high explosives.
