Military and commercial orbital compute architectures are converging on identical technical designs creating a dual-use governance challenge where the same infrastructure serves both missile defense and civilian applications
The Space Data Network is explicitly framed as 'a space-based internet' comprising a multi-orbit hybrid of military and commercial satellites with inter-satellite links and distributed processing. This is architecturally identical to what commercial orbital data center operators are building — networks of compute nodes in various orbits with high-speed inter-satellite links. The military is building this architecture independently for Golden Dome, while commercial operators are building to SDA Tranche 1 standards (as evidenced by Axiom/Kepler partnerships documented elsewhere in the KB). The convergence is not incidental — these are two parallel build-outs of the same underlying architectural concept for different use cases. This creates a novel governance challenge: who sets the protocols for an AI battle management system that also uses commercial satellites? The SDN's hybrid military-commercial architecture is a commons governance problem where military needs and commercial needs must coexist on shared orbital infrastructure. This is categorically different from historical military-commercial separation because the physics of orbital mechanics and the economics of satellite networks force infrastructure sharing rather than parallel systems.
Relevant Notes:
- nearly all space technology is dual-use making arms control in orbit impossible without banning the commercial applications themselves
- space governance gaps are widening not narrowing because technology advances exponentially while institutional design advances linearly
