A prototype of a robot jet fighter designed to take off and land on an aircraft carrier has made its maiden flight in the US.



The Pegasus, also known as the X-47A, flew for 12 minutes before successfully landing on a runway at the Naval Air Warfare Centre in California’s Owens Valley.



The arrowhead-shaped plane completed the flight autonomously, following a series of pre-programmed way points.



The plane flew to about 3,300 feet and reached a speed of about 150 mph, said a spokesman for the Northrop Grumman Corporation, who made the prototype.

The plane is 27.9 feet long and has a wingspan of 27.8 feet
