Starshield

SpaceX's secure government/military satellite-communications constellation—built on the Starlink bus for high-assurance connectivity, Earth observation, and hosted classified payloads.

Overview

Starshield is the classified, government-only derivative of SpaceX’s commercial Starlink constellation. It provides a proliferated low-Earth-orbit mesh network purpose-built for U.S. national-security users, coupling optical inter-satellite links with high-assurance cryptography. While civil Starlink delivers broadband to consumers, Starshield is the dedicated secure line that carries sensitive military traffic, hosts Earth-observation and signals-intelligence payloads, and, increasingly, forms the physical backbone of the Space Force’s sensor-to-shooter data transport layer. SpaceX explicitly distinguishes the two networks, noting that Starshield alone adds the “additional high-assurance cryptographic capability” required by defense customers FedScoop.
