Amprius Technologies and BAE Systems marked a significant milestone as the high-density silicon anode batteries from Amprius played a crucial role in powering BAE Systems’ first successful stratospheric flight trial. The trial involved PHASA-35, a High-Altitude Pseudo Satellite (HAPS) Uncrewed Aerial System (UAS) developed by BAE Systems’ subsidiary, Prismatic Ltd., with plans for operation in the stratosphere, above weather conditions and conventional air traffic.
During a recent test-flight in New Mexico, PHASA-35 achieved an impressive altitude of over 66,000 feet, reaching the stratosphere and returning to the ground safely. This flight allowed engineers to assess the experimental solar-electric drone’s performance within the Earth’s atmosphere.

PHASA-35, also known as Persistent High Altitude Solar Aircraft, exemplifies BAE Systems’ dedication to technological innovation and expanding its presence in the market. The High-Altitude Long Endurance (HALE) vehicle utilizes solar power during the day and relies on batteries during the night. The combination of a long-life battery and highly efficient solar technology allows the aircraft to potentially maintain flight for up to a year while operating in the upper regions of the atmosphere. This unique combination of aero structure design and advanced solar technology positions PHASA-35 as a game-changer in the air and space market.
The collaboration between Amprius and BAE Systems began in October 2022, with the two companies entering into a three-year cooperation agreement. Their joint efforts aimed to explore business opportunities enabled by the use and supply of Amprius’ silicon anode batteries for BAE Systems’ electric products currently under development in the UK.
