IonQ Subsidiary Skyloom Reaches 84 On-Orbit Optical Terminals Supporting SDA Constellation

Space-based optical communications developer Skyloom Global—a subsidiary of IonQ (NYSE: IONQ)—has deployed dozens of additional Optical Communication Terminals (OCTs) into low-Earth orbit (LEO). Launched aboard a SpaceX Falcon 9 rocket from Vandenberg Space Force Base, the optical payloads were integrated onto York Space Systems satellites supporting the U.S. Space Development Agency’s (SDA) Proliferated Warfighter Space Architecture (PWSA).

Laser Communications Infrastructure and Constellation Scaling

The deployment expands one of the largest operational laser communications (lasercomm) payload footprints currently in low-Earth orbit:

• SDA Tranche 1 Transport Layer: The additional terminals advance the completion of the SDA’s Tranche 1 Transport Layer constellation, creating high-throughput, low-latency mesh networks for secure military and national defense communications.

• Interoperable Free-Space Optics: Skyloom's terminals conform to official SDA optical interoperability standards, enabling direct optical cross-links (OISLs) between orbiting space vehicles and ground stations.

• Quantum Networking Roadmap: Following IonQ's acquisition of Skyloom in January 2026, the optical transport layer provides the physical hardware foundation for future distributed quantum entanglement, free-space quantum key distribution (QKD), and space-to-ground quantum interconnects.

Led by IonQ President of Quantum Platform Jordan Shapiro, the expansion demonstrates industrial-scale manufacturing and deployment of U.S.-built optical space communications infrastructure.
