Triton, the U.S. Navy variant of Northrop Grumman’s high-altitude unmanned spy aircraft, made a 90-minute maiden flight May 22 in Palmdale.

The Navy could buy as many as 68 of the aircraft, a Northrop Grumman spokesman said.

The Triton can stay aloft for more than 24 hours, flying at an altitude of 10 miles.

Northrop Grumman does engineering work on the aircraft at its unmanned systems center of excellence in Rancho Bernardo.

Subcontractors on the Triton project include Aurora Flight Sciences, BAE Systems, Curtis-Wright Corp., L3 Communications, Raytheon, Rolls-Royce, Sierra Nevada Corp. and Vought Aircraft Industries.
