Persistent High Altitude Solar Aircraft (PHASA-35®) has the potential to stay airborne for a year.
PHASA-35, a 35m wingspan solar-electric aircraft, has successfully completed its maiden flight. The landmark flight paves the way to this new aircraft becoming a game changer in the air and space market, plugging the gap between aircraft and satellite technology.    

PHASA-35 has been designed, built and now flown in less than two years as part of a collaboration between ourselves and Prismatic Ltd, which we agreed to acquire last year. Designed to operate unmanned in the stratosphere, above the weather and conventional air traffic, PHASA-35 offers a persistent and affordable alternative to satellites combined with the flexibility of an aircraft, which could be used for a range of valuable applications including forest fire detection and maritime surveillance.   

Sponsored by the UK’s Defence Science and Technology Laboratory (DSTL) and Australian Defence Science and Technology Group (DSTG), the successful flight trials took place at the Royal Australian Air Force (RAAF) Woomera Test Range in South Australia. 

The trials marked the first fully integrated flight test of the PHASA-35 system, delivering rapid proof of capability from design to flight in just 20 months. They are the culmination of efforts from a collaborative team of British experts from Prismatic in Hampshire – where two full-sized concept aircraft were built last year – working alongside our engineers in Lancashire, where the aircraft underwent further integration testing prior to flight trials.
