Top-Secret US Underwater Drone 'Manta Ray' Spotted on Google Maps

The autonomous vessel, designed for long-term missions, was seen docked at a California naval base before the image was removed.

Manta Ray is an unmanned underwater vehicle developed by Northrop Grumman for the US Navy.
It can hibernate on the seafloor for extended periods without refueling, making it ideal for long-range operations.
The drone's modular design allows it to be transported in standard shipping containers and assembled in the field.
Recent tests off the coast of Southern California validated its readiness for real-world deployment.
The Manta Ray's development is part of a strategic effort to counter underwater drone advancements by Russia and China.
