Formerly known as the “Air Mule,” this is a flying taxi, or maybe a future unmanned ambulance.

Nine years ago, the Air Mule was an almost-believable concept: a flying robot taxi that could get people out of dangerous battlefields without endangering a pilot or crew. It was the exact sort of gizmo one expects from Popular Science: an amazing machine of the future, almost like a flying car, that seemed plausible but just out of reach.

OSLO—Two Norwegian companies are taking the lead in the race to build the world’s first crewless, autonomously operated ship, an advance that could mark a turning point in seaborne trade.

Dubbed by shipping executives the “Tesla of the Seas,” the Yara Birkeland now under development is scheduled in late 2018 to start sailing fertilizer 37 miles down a fiord from a production facility to the port of Larvik. Using the Global Positioning System, radar, cameras and sensors, the electric ship is designed to navigate itself around other boat traffic and to dock on its own.

The vessel will cost $25 million, about three times as much as a conventional container ship of its size, but its backers say without need for fuel or crew it promises to cut annual operating costs by up to 90%. The 100-container ship is scheduled to be in the water toward the end of next year, though initially it will be tested with a human at the controls.
