Menlo Park - Facebook announced on Thursday it has completed building its first full-scale drone, which has the wingspan of a Boeing 737 and will provide internet access to the most remote parts of the world.
The company said it will test it in the US later this year.
The plane will weigh about 400kg, said Yael Maguire, the company's engineering director of connectivity. It will hover between 20km and 30km above the altitude of commercial airplanes, so that it is not affected by problematic weather.
"Our mission is to connect everybody in the world," said Jay Parikh, vice president of engineering. "This is going to be a great opportunity for us to motivate the industry to move faster on this technology."
The drone, which was built in 14 months, is able to fly in the air for 90 days at a time, Maguire said. Helium balloons will be attached to the plane and float it up into the air. The drones have a wingspan of 42m.

Because the planes must constantly move to stay aloft, they will circle a 3km radius, Parikh said. During the day, they will float up to 30km and at night will drift down to 20km to conserve energy.

The drones are part of a programme called Aquila, which is geared toward the 10% of the population that does not have any Internet access, executives said.
Separately, Facebook a year ago launched Internet.org, an initiative to provide internet access to the two-thirds of the world that do not have a reliable connection.
Parikh said Facebook is not planning to sell the drones but will use them to expand internet access.
Although Facebook does not immediately face policy or legal hurdles in testing its drone in the US, Maguire said, it is the first company to fly at such altitudes. It has a team working with policymakers to help set guidelines.
