British engineers have successfully completed a stratospheric flight trial of BAE Systems’ High Altitude Pseudo-Satellite (HAPS) Uncrewed Aerial System (UAS) - PHASA-35.
Over a 24-hour period, PHASA-35 soared to more than 66,000 feet, reaching the stratosphere, before landing successfully. The trial, completed last month in New Mexico in the USA, allowed engineers to assess the performance of the experimental solar-electric drone within the outer-reaches of the planet’s atmosphere.
The flight marks a significant milestone in PHASA-35’s development which began in 2018. Designed by BAE Systems’ subsidiary Prismatic Ltd to operate above the weather and conventional air traffic, it has the potential to provide a persistent and stable platform for various uses including ultra-long endurance intelligence, surveillance and reconnaissance, as well as security.
It also has the potential to be used in the delivery of communications networks including 4G and 5G and could be used in a wide range of applications, such as disaster relief and border protection, as an alternative to traditional airborne and satellite systems.
The PHASA-35 programme sits within FalconWorks™, a new centre for advanced and agile research and development within BAE Systems’ Air sector, designed to deliver a range of cutting-edge combat air capabilities to the UK and its allies.
