Met Office Supports BAE Systems Prismatic’s Successful High-Altitude Flight

The Met Office, renowned for its expertise in meteorology, has played a crucial role in supporting the successful flight of BAE Systems Prismatic’s PHASA-35 high altitude Uncrewed Air System. The PHASA-35 platform, weighing only 150kg and boasting a wingspan equivalent to a Boeing 737, is designed to provide an ultra-lightweight, persistent platform for various applications, including monitoring, surveillance, disaster relief, and 5G communications. With the ability to remain airborne for months at altitudes of 50-65,000 feet, accurate weather forecasting is of utmost importance for launch, climb, cruise, and landing. The Met Office’s expert scientists have provided forecast model data and scientific analysis, ensuring optimal flight conditions throughout the journey. They have also collaborated with partners IBL to integrate weather information into BAE Systems Prismatic’s mission planning process. Even in the stratosphere, where the aircraft operates beyond typical weather patterns, the Met Office continues to provide valuable support by assisting with flight optimization and boundary identification. Wayne Elliott, Head of Defence at the Met Office, expressed delight at their involvement and emphasized the importance of their tailored insights and collaboration with technology partner IBL. The Met Office’s expertise extends to understanding the platform’s global usability, aiding future test and operational flights. The successful collaboration between BAE Systems, the Met Office, and IBL demonstrates the UK’s world-leading technology and capabilities.
