Space Systems Command at Los Angeles Air Force Base awarded Viasat Inc. and Intelsat General Communications LLC a combined $437,665,005 on May 22 to design, build, and deliver four jam-resistant geostationary satellites under the Protected Tactical Satcom-Global program. The awards continue work on one of Space Force's highest-priority communications efforts, providing allied and joint force commanders with survivable satellite connectivity in environments where adversaries are actively targeting U.S. space-based communications infrastructure. Of the $437. Delivery of the four PTS-G spacecraft is scheduled for March 2029, giving both contractors roughly three years to complete satellite bus manufacturing, payload integration, testing, and ground system delivery.
The contract scope covers not just the satellites themselves but also satellite bus and payload manufacturing, ground integration components, and associated hardware — a scope that extends well beyond the prime contractors' own facilities and into a broad supply chain of satellite component manufacturers, ground systems integrators, and test service providers.
The PTS-G Program
Protected Tactical Satcom-Global is Space Force's answer to a specific operational problem: U.S. tactical forces in contested theaters depend on satellite communications for everything from fire control coordination to logistics management, and adversaries including China and Russia have invested heavily in the ability to jam, spoof, and physically attack those satellites. Existing protected military SATCOM constellations, while capable, were not designed with the distributed, resilient architectures that Space Force now considers essential for peer-competitor conflict.
PTS-G addresses this through a combination of technical approaches. The four spacecraft will operate in geostationary orbit and use dual X-band and Ka-band communications — a dual-band architecture that provides flexibility across different terminal types and allows frequency management to mitigate jamming attempts. Geostationary coverage is particularly important for naval and ground forces operating in fixed theaters, where a persistent overhead presence is more operationally valuable than the intermittent passes of low-earth orbit constellations.
The program's anti-jam focus reflects lessons from Ukraine, where both sides have conducted sustained electronic warfare campaigns targeting satellite communications links. The U.S. military's experience advising Ukrainian forces, combined with its own wargaming of high-end conflict scenarios, has accelerated demand for protected SATCOM that can operate through jamming environments rather than simply hoping adversaries don't target them. The four PTS-G spacecraft are designed to provide that survivable backbone for tactical commanders who need reliable communications when it matters most.
Viasat brings significant experience in protected military SATCOM to this award, having developed anti-jam terminal technology and satellite payloads for DoD programs over many years. Intelsat General Communications, the government services arm of Intelsat, contributes deep experience in geostationary satellite operations and commercial satellite manufacturing. The combination reflects Space Force's interest in leveraging both companies' distinct capabilities rather than selecting a single integrator for the entire PTS-G production effort.
What It Means for Contractors
The $437.7 million combined ceiling is a starting point, not an endpoint. Both Viasat and Intelsat General will need to execute satellite programs that are among the most technically demanding in the defense industry, and neither company builds every component of a GEO communications satellite in-house. That creates subcontracting opportunities across a wide range of specialties: satellite bus structures, solar arrays, electric propulsion systems, X-band and Ka-band transponders, onboard processing hardware, thermal management systems, and the ground support equipment used during manufacturing and pre-launch testing.
The ground integration components explicitly included in the contract scope are particularly important for systems integrators and software firms. Protected military SATCOM is not useful without compatible ground terminals and network management systems, and the delivery of four new spacecraft will require updates to ground infrastructure, operator training systems, and integration with existing military satellite communications networks. Companies that provide ground system software, network operations center capabilities, or military SATCOM terminal hardware should be actively developing relationships with both prime contractors as the program moves into detailed design.
The five-offer competition that produced this award is a meaningful signal about the state of the protected military SATCOM market. Five credible competitors in a program of this technical complexity suggests that Space Force has successfully expanded the industrial base beyond the two or three traditional large satellite primes that once dominated military GEO programs. For smaller satellite component manufacturers and systems integrators, that competitive field is an opportunity: primes competing for task orders under an IDIQ structure need suppliers who can help them win on price and schedule, not just technical capability.
The March 2029 delivery schedule also has foreign military sales implications worth tracking. Allied nations operating in the same contested environments as U.S. forces have strong incentives to procure access to PTS-G capabilities or compatible protected SATCOM services. FMS cases tied to PTS-G ground terminals or satellite access agreements could generate additional procurement activity for U.S. defense contractors with allied customer relationships in Europe, the Middle East, and the Indo-Pacific. RDT&E funding obligated at the time of award indicates that a portion of the work to be done under the contract is classified as research, development, test, and evaluation activity rather than production procurement. For specialized test and evaluation firms, satellite integration labs, and range support contractors that support GEO satellite qualification testing, the RDT&E-funded work packages within PTS-G represent an entry point that does not require production-scale manufacturing capacity. Smaller, technically specialized firms often find that RDT&E contract vehicles are more accessible than production contracts precisely because the scope is defined by engineering deliverables rather than unit quantities and manufacturing throughput.
The broader competitive dynamic in protected military SATCOM is also worth monitoring beyond this single award. Space Force's Protected Tactical Satcom program family — which PTS-G is part of — represents a multi-year, multi-contract investment in survivable military communications. Firms that establish themselves as suppliers or service providers on PTS-G through the current Viasat and Intelsat General contracts are positioning themselves for future protected SATCOM competition, as the Space Force continues to expand and harden its communications architecture against the growing threat to space-based systems.
