What Aechelon Technology does

Aechelon Technology is a U.S. defense and aerospace technology company founded in 1998 and headquartered in South San Francisco, California. The company builds GPU-accelerated, physics-based synthetic reality platforms used for flight simulation, mission rehearsal, sensor operator training, and AI/ML data generation. Its core product family includes the Nucleus multi-GPU image generator (8K at 240Hz), the SkyBeam rapid terrain database update system, Nexus military-grade secure storage, and the Radar Toolkit (RTK) acquired from Compro Computer Services in December 2024. Aechelon serves every branch of the U.S. Armed Forces, U.S. Special Operations Command, defense prime contractors (notably Lockheed Martin on the F-35 program), and allied military forces across North America, Europe, and Asia-Pacific. In September 2025 the company launched Project Orbion, the first AI-enabled Digital Twin of the Earth, integrating satellite imagery from partners ICEYE and BlackSky with Niantic Spatial's geospatial platform.

Aechelon generates revenue through four streams: product licensing (perpetual and term licenses for Nucleus, SkyBeam, and Radar Toolkit), professional services (integration, customization, and training), subscription/SaaS (including Project Orbion digital twin access), and hardware system sales (integrated visual systems and computing infrastructure often bundled as turnkey solutions). Pricing is quote-based and tailored to program requirements, procured through DoD contracting vehicles including IDIQ and GSA Schedule, with multi-year contract terms. The go-to-market is sales-led enterprise motion targeting defense agencies and prime contractors, supplemented by industry events (I/ITSEC, GEOINT Symposium) and channel partnerships with defense primes and technology partners (Varjo for mixed reality, NVIDIA for GPU compute). In June 2026, Shield AI completed its acquisition of Aechelon at a $12.7 billion post-money valuation, with Aechelon now operating as a division within Shield AI under continued leadership of co-founder and CEO Nacho Sanz-Pastor.
