Amprius’ batteries power first stratospheric flight for BAE Systems drone

Amprius Technologies (AMPX) announced that its high-density batteries played a significant role in powering BAE Systems’ (BAESY) first successful stratospheric flight trial. PHASA-35, the High-Altitude Pseudo Satellite HAPS Uncrewed Aerial System designed by BAE Systems’ subsidiary Prismatic Ltd., is planned to operate above the weather and conventional air traffic. During a recent test flight, the PHASA-35 crossed an altitude of more than 66,000 feet, reaching the stratosphere, before landing successfully. The trial, completed last month in New Mexico, allowed engineers to assess the experimental solar-electric drone within the edges of the planet’s atmosphere. “Amprius is proud to be recognized as a key partner to BAE Systems supporting their development of the PHASA-35(R),” said Dr. Kang Sun, Chief Executive Offer of Amprius. “This ultralight platform provides an alternative and flexible approach to traditional systems such as satellites or conventionally powered aircraft. As we develop our next-generation of industry-leading silicon anode batteries, we look forward to helping BAE Systems and Prismatic further enhance the capabilities of their PHASA-35 aircraft.”
