SES Space & Defense to Provide Hybrid Space-Based Architecture to U.S. Department of Defense

Secure integrated multi-orbit network (SIMON™) delivered by SES Space & Defense will support rapid, uninterrupted data transmission

RESTON, Va., May 13, 2025–(BUSINESS WIRE)–SES Space & Defense, a wholly-owned subsidiary of SES, joins the Defense Innovation Unit’s (DIU) Hybrid Space Architecture Network initiative. SES’s Hybrid Space Architecture II project will showcase an automatically orchestrated secure integrated multi-orbit network that interconnects commercial and government networks to deliver assured and affordable, low-latency, multi-path communications across a scalable and resilient multi-domain network.

SES Space & Defense will deliver an engineered multi-orbit network leveraging Secure Integrated Multi-Orbit Networking (SIMON™). This will enable always-on connectivity as an affordable, resilient alternative to traditional Primary, Alternate, Contingency, and Emergency (PACE) and auto-PACE operations currently used by warfighters across the Department of Defense (DoD) worldwide. By blending LEO, MEO, and GEO capabilities in a purposeful manner, SIMON™ ensures that the warfighters’ data can affordably traverse multiple orbital regimes simultaneously, adapting and adjusting in real time to changing mission requirements.

“With SIMON™, warfighters will have the ability to ‘set and forget’ their user terminals and affordably realize assured connectivity across multiple orbits,” says David Fields, President and CEO of SES Space & Defense. “This transformational approach solves a decades-long dichotomy of affordability versus resilience, providing SATCOM agility, flexibility, and reliability for the forward deployed personnel.”
