# Military and commercial space architectures are converging on the same distributed orbital compute design because both require low-latency data processing across multi-orbit satellite networks

The Space Data Network is explicitly framed as 'a space-based internet' comprising interlinked satellites across multiple orbits with distributed data processing capabilities. This architecture is structurally identical to what commercial orbital data center operators are building: compute nodes in various orbits connected by high-speed inter-satellite links. The convergence is not coincidental—both military and commercial use cases face the same fundamental constraint: latency-sensitive applications (missile defense for military, real-time Earth observation analytics for commercial) cannot tolerate ground-based processing delays. The SDN is designed as a 'hybrid' architecture explicitly incorporating both classified military and unclassified commercial communications satellites, indicating the Pentagon recognizes it cannot build this infrastructure in isolation. Commercial ODC operators like Axiom and Kepler are already building to SDA Tranche 1 standards, demonstrating technical compatibility. This creates a dual-use infrastructure dynamic where military requirements drive initial architecture development and procurement funding, while commercial operators can serve both markets with the same underlying technology platform.
