US Military News – While the surface fleet gets the headlines, the real revolution is happening in the shadows of the deep. This is DARPA’s Manta Ray, an extra-large unmanned underwater vehicle that looks more like a sci-fi spacecraft than a submarine. In 2026, following successful full-scale testing, this autonomous glider is redefining long-endurance missions. Unlike traditional subs, the Manta Ray doesn’t need a crew or constant refueling. It uses buoyancy-driven gliding to move silently through the water for months at a time. It can even “hibernate” on the seafloor, anchoring itself in a low-power state until it’s triggered by a mission command. With its modular design, it can carry anything from sensors to secret payloads. It is the ultimate persistent predator, designed to operate in contested waters where manned ships dare not go. The Navy’s ghost fleet has officially gone deep, and the ocean floor will never be the same. #science #technology #future
