The ultra-light Zephyr 3 is expected to climb to 132,000ft â †more than 36,000ft higher than any other unmanned aircraft. The plane weighs only 26 ½lb â †the same as a one-year-old child â †despite its 40ft wingspan.
Zephyr 3 has five tiny 1kW electric motors to power its propellers, fuelled by solar panels on long carbon composite wing frames.
An industry source said planes such as the Zephyr were able to store solar power for use at night, allowing them to stay aloft for weeks.
If the project succeeds, military officials believe they could eventually have squadrons of Zephyr 3 unmanned drones providing continuous radio, telephone or photo coverage over crisis areas ranging from battlefields to natural disasters.
