Multiple Choice

Which agency is driving the Department's shift toward a distributed pLEO architecture?

Proliferated low Earth orbit involves using a large number of small satellites in low altitude to create a flexible, resilient, and low-latency network for global coverage. The agency driving the department’s shift toward this distributed pLEO architecture is the Space Development Agency, a DoD organization established to rapidly develop and field new space architectures. SDA focuses on delivering a scalable, disaggregated constellation with a transport layer to pass data quickly and a sensing/mission layer to support warfighting needs, instead of relying on a handful of large, expensive satellites. This approach enhances resilience against threats, reduces single-point failures, and speeds up delivery of critical space capabilities across the force. NASA and NOAA are civilian agencies with science and weather missions, and while DoD overall pursues space advances, the specific push toward proliferated pLEO is driven by SDA within the Department.
