BAE Systems and Hanwha Systems to jointly develop advanced multi-sensor satellite system

BAE Systems and South Korea’s Hanwha Systems have signed a memorandum of understanding (MoU) to jointly develop an advanced multi-sensor satellite system, the two companies announced on 10 June 2025.

The collaboration will look to integrate BAE Systems’ ultra-wideband radio frequency (RF) sensor technology with Hanwha Systems’ cutting-edge small synthetic aperture radar (SAR) satellite capabilities. The ambition is to explore the creation of a system that will use a range of sensors to collect RF and SAR data, which will be analysed by machine learning using onboard edge processors to deliver precise, timely, and high-resolution intelligence. By fusing different types of satellite data, the system is expected to significantly enhance situational awareness and offer a formidable space-based surveillance asset.

“Bringing together our pedigree in space with Hanwha Systems’ expertise in SAR satellites represents an exciting opportunity to progress ISR capabilities from space for international markets,” Rachael Hoyle, space director for BAE Systems Digital Intelligence, was quoted as saying in a joint press release. “We’re looking forwards to building this relationship and advancing space technologies together.”

Sung-Chan Song, head of Hanwha Systems’ Space Division, added, “Small SAR satellites are becoming increasingly recognised as invaluable resources for surveillance and reconnaissance. Hanwha Systems is proud to collaborate with BAE Systems as we look to further expand our presence in the global satellite market.”

BAE Systems expects to launch its first low Earth orbit (LEO) cluster of satellites in 2025. Known as Azalea, the mission will boost domestic and international markets’ ability to understand the threats and hazards in, from and through space. To deliver this it works collaboratively with a range of partners around the globe.

Hanwha Systems, meanwhile, is the provider of the SAR payload for the 425 Project: South Korea’s first military reconnaissance satellite programme. In December 2023 the company successfully launched a 1 m resolution small SAR satellite developed entirely with domestic technology, demonstrating its leadership in civilian-led Earth observation and surveillance capabilities. Hanwha is also participating in South Korea’s first LEO communications satellite development project, led by the Agency for Defense Development, and is actively contributing to the creation of an independent military satellite constellation.
