Space Force Laser Crosslink Program Advances to Flight Hardware Production
General Atomics Terminal Clears Independent Verification, Enters Phase 3 Development
A U.S. Space Force program to establish standardized laser crosslinks between satellites has advanced to flight hardware production and demonstration, with General Atomics Electromagnetic Systems tapped to lead Phase 3 of the Enterprise Space Terminal program following successful independent verification of the company’s optical communication terminal.
“Completion of Phase 2 marks a significant milestone for our team underscoring the maturing and successful validation of key subsystems of our OCT.”

The independent verification was conducted at MIT Lincoln Laboratory’s Optical Terminal Verification Testbed (OTVT), which confirmed that the GA-EMS optical communication terminal — or OCT — meets performance, interoperability, and technical readiness thresholds required to support standardized satellite laser crosslinks. Phase 3 transitions the program from prototype development into the integration and demonstration of a complete, flight-ready laser communications terminal.
The Enterprise Space Terminal program is designed to establish a common optical communications architecture enabling spacecraft from multiple programs and vendors to exchange data directly using a standardized enterprise waveform. By supporting high-capacity laser crosslinks beyond low Earth orbit, the system is intended to reduce dependence on ground relay stations and accelerate delivery of time-critical data to joint forces and national security missions.
GA-EMS is serving as prime contractor, teamed with L3Harris on the modem subsystem and Advanced Space, which provides performance modeling for the overall system architecture.
“Completion of Phase 2 marks a significant milestone for our team underscoring the maturing and successful validation of key subsystems of our OCT through rigorous analysis and testing,” said Scott Forney, president of GA-EMS. “This achievement positions us well as we move into Phase 3, where we will integrate and demonstrate a flight laser communications terminal. We are excited to take this next step in delivering robust, mission-ready capability that advances resilient, high-capacity space network connectivity for national security operations.”
The program builds on a multi-phase development effort that has progressively moved the OCT architecture from initial concept through subsystem testing and formal government verification. The successful OTVT test campaign confirmed the terminal architecture is ready for full system integration and flight terminal development.
“The successful execution of Phases 1 and 2 reflects the strength of our technical approach and our team’s ability to translate innovative optical communications concepts into validated, high-performing hardware,” said Klaus Etzel, vice president of GA-EMS Remote Space Sensing Systems. “As we transition into Phase 3, we are focused on integrating and demonstrating a complete system that is not only mission-capable, but also scalable and producible to meet the evolving needs of resilient space architectures.”
The Enterprise Space Terminal program reflects the Space Force’s broader push to reduce single points of failure in space communications infrastructure by enabling direct satellite-to-satellite data transfer via laser crosslinks. A standardized terminal approach allows spacecraft from different programs and prime contractors to operate on a common network, increasing interoperability and reducing the infrastructure burden associated with ground-based relay systems.
Optical or laser communications offer substantially higher data throughput than traditional radio frequency links, while also providing greater resistance to jamming and interference — factors increasingly central to national security space operations. The ability to route data directly between satellites at various orbital altitudes, without relying on ground stations, is viewed as a key enabler of more responsive and resilient space architectures.
The verification milestone at MIT Lincoln Laboratory’s OTVT — one of the U.S. government’s primary facilities for evaluating the readiness of optical communications terminals prior to space-based demonstration — marks the formal close of Phase 2 and clears the path for hardware to move from laboratory environments into flight-qualified systems under Phase 3.
