BAE Systems has revealed its PHASA-35 concept for a solar-powered high-altitude long-endurance (HALE) unmanned aerial vehicle (UAV) that can remain aloft for up to a year.

The Persistent High Altitude Solar Aircraft (PHASA) UAV features a 35 m wingspan, giving it the moniker PHASA-35. According to the company, a quarter-scale demonstrator known as PHASA-8 flew in 2017 and work is now already under way to prepare the first full-scale aircraft to be ready for flight tests in 2019.

The 150 kg PHASA-35 is being developed by BAE Systems in partnership with UK company Prismatic, which bills itself as an expert in the design, manufacture, and delivery of innovative, high-value aerospace products and systems.
