The propeller-driven drone has civilian and military applications, including inspecting underwater mines, and can linger silently in the water for a long time.
Boeing has been under contract to build the Orca Extra Large Unmanned Undersea Vehicles, or XLUUVs, since it won the contract over Lockheed Martin in February 2019.

There could be melting of the glacier at the key points holding it to the land. A robotic submarine has gotten back from the dark underbelly of one of the largest Antarctica glaciers with chilling information- it could be melting rapidly than we formerly thought.
