Safran Electronics & Defense and Hemeria signed a memorandum of understanding on 13 June 2026 to build an electromagnetic reconnaissance system using stratospheric balloons. The project integrates Hemeria’s balloon platform with Safran.AI sensors linked to artificial intelligence models for real-time detection of radar and communications signals across land, air, and sea. Positioned for military intelligence and electronic warfare, the system enables persistent wide-area surveillance from the stratosphere, bypassing traditional ISR altitude limits. No schedule or prototype status has been disclosed, but the partnership targets long-range, high-altitude signal exploitation. This collaboration signals a shift toward AI-driven, balloon-based intelligence platforms in defense operations.
