Japan's SoftBank Corp announced that its large-scale High Altitude Platform Station (HAPS), named Sunglider, has successfully achieved stratospheric flight. The solar-powered uncrewed aircraft system (UAS) designed for HAPS stratospheric telecommunications was utilised in a field trial conducted by AeroVironment and the US Department of Defense (DoD) in New Mexico, USA, in early August 2024. According to SoftBank, Sunglider is larger than other publicly announced HAPS UAS, boasting a wingspan of 78 meters and the capability to carry payloads weighing up to 75 kg.

Enhanced Features and Capabilities of Sunglider
The company said this large-scale UAS is engineered to deliver stable, high-speed, and robust mobile connectivity. The aircraft used in the stratospheric field trial was an improved version that incorporated structural and functional enhancements to enable better performance than its predecessor, SoftBank explained.
Junichi Miyakawa, President and CEO of SoftBank Corp, said, "SoftBank began its HAPS program in 2017 as a global pioneer and has since led the industry in research and development, field trials, standardisation, and other activities to realise HAPS-based services. For our aircraft platform, we've been working with our partner AeroVironment to develop Sunglider, an industry-leading large-scale HAPS aircraft. The HAPS service we're aiming to provide will offer high-speed, high-capacity, high-quality, and stable communications, which is only possible with a large-scale aircraft."
"Going forward, we'll continue to challenge ourselves to achieve further performance enhancements and realise long-duration flights and optical wireless communications. Building on the achievements from this field trial, we'll accelerate our efforts towards commercialising HAPS."
