The silent spy drone that could stay in the sky forever
- Laser used to beam power to drone
- Recharging system kept craft in air for 48 hours
A silent spy drone has been kept in the air for 48 hours using a radical new laser power system.
Military scientists from Lockheed Martin were able to wirelessly beam power to the drone to increase its flight time by 2,400 per cent.
They say the system could eventually keep military spy drones in the sky forever.
The Stalker Unmanned Aerial System (UAS) flight time to more than 48 hours. This increase in flight duration represents an improvement of 2,400 percent.
The small, silent UAS is already used by Special Operations Forces since 2006 to perform intelligence, surveillance and reconnaissance missions.
