BAE Systems has flown the PHASA-35 solar-powered high-altitude long-endurance (HALE) unmanned aerial vehicle (UAV) that can remain aloft for up to a year, the company announced on 17 February.
The company said that the successful flight trials took place at the Royal Australian Air Force (RAAF) Woomera Test Range in South Australia, although it did not note the duration of this milestone.
