The U.S. Space Force Space Systems Command has issued a $437,700,000 combined delivery order to Viasat Inc. under the Protected Tactical Satcom - Ground program's Swarm 1 contract vehicle, according to Space Systems Command communications. The delivery order tasks Viasat with designing, building, and delivering a dual-band communications satellite that will provide protected tactical satellite communications to U.S. military users. The PTS-G program represents the Space Force's strategy for providing resilient, anti-jam protected tactical SATCOM through a proliferated constellation of smaller, more affordable satellites rather than the large, expensive high-power SATCOM satellites that have historically served this mission. Viasat's selection reflects the company's track record in protected satellite communications technology developed over decades of commercial and government satellite program execution.
The Protected Tactical Satcom program addresses a critical vulnerability in U.S. military communications: the concentration of protected SATCOM capability on a small number of high-value satellite assets that adversaries have identified as priority targets for electronic warfare, directed energy, and kinetic anti-satellite attack. A small constellation of large, expensive satellites provides a high-capacity communications capability but also represents a relatively small number of targets that adversaries can plan against. The Space Force's response to this vulnerability is to transition toward larger constellations of smaller, less expensive satellites where the loss of any individual satellite does not catastrophically degrade the overall communications capability.
PTS-G Architecture and Swarm Approach
The PTS-G program acquires protected tactical SATCOM capacity through a novel "swarm" acquisition approach that contracts for multiple satellites across multiple vendors simultaneously, building a diverse constellation with no single point of failure. The Swarm 1 delivery under the current contract will produce multiple satellites across a small group of vendors, each contributing different technical approaches and implementations of the protected communications capability. Distributing satellite production across multiple vendors also builds a broader industrial base for protected SATCOM satellites, reducing dependence on any single contractor and maintaining competition for future swarm procurements.
Viasat's specific delivery order covers a dual-band satellite — a satellite capable of operating in two different frequency bands, providing the government flexibility to route communications through either band depending on the jamming environment, link conditions, or user requirements. Multi-band capability is a key attribute of protected SATCOM systems, because adversaries optimizing jamming against a single-band system may be unable to simultaneously jam both bands at the power levels required to deny communications. This operational resilience is central to the PTS-G program's mission of ensuring that military units can maintain protected SATCOM connectivity even in a heavily contested electromagnetic environment.
The $437.7 million delivery order value reflects the significant engineering and manufacturing investment required to design, build, and test a space-qualified protected SATCOM satellite. Satellite development involves specialized engineering disciplines, very high quality and reliability standards appropriate for a system that must operate unattended in the harsh space environment for 10 to 15 years, and extensive ground testing that simulates the thermal vacuum, vibration, and radiation environments the satellite will experience on orbit. The delivery order funds not just the satellite hardware but the integration, testing, and launch operations support associated with fielding a new satellite to an operational orbit.
Viasat's Role in Government Protected SATCOM
Viasat has been a significant provider of protected satellite communications hardware and services to the U.S. government for decades. The company develops and produces the Link 16 tactical data link terminals used by U.S. and allied military aircraft, ships, and ground forces, and has developed multiple generations of commercial and government satellite technology. Its selection for the PTS-G Swarm 1 delivery order reflects both its existing satellite bus and payload technology and its deep understanding of military tactical communications requirements developed through its Link 16 and other defense product lines.
The PTS-G program's use of delivery orders against a base contract vehicle allows Space Systems Command to efficiently procure multiple satellites across multiple vendors without executing separate full and open competitions for each satellite. The competition occurred at the IDIQ contract level, where vendors competed for positions on the Swarm 1 vehicle — the delivery orders then represent the government's exercise of the contract to procure actual satellites from the qualified vendors. This two-step structure streamlines procurement while maintaining competition at the vehicle level.
Viasat's Swarm 1 delivery order is part of a larger Space Force investment in protected tactical SATCOM that will ultimately include additional swarm procurements as the constellation builds out over the coming decade. Each swarm procurement will add capacity to the PTS-G constellation, improving global coverage and increasing the resilience of the overall communications architecture. Contractors who establish themselves in the PTS-G supply chain through the current swarm are well positioned for follow-on swarm procurements as the program matures.
What It Means for Contractors
For the broader defense space industry, the Viasat PTS-G delivery order illustrates several important characteristics of the Space Force's current satellite procurement strategy. The emphasis on affordability, proliferation, and multiple vendors reflects a fundamental strategic choice to accept individual satellite performance trade-offs in exchange for resilience through numbers and diversity. Contractors across the satellite industry should recognize that Space Force programs are increasingly structured to support this proliferated, diverse constellation model rather than the traditional single-vendor high-value satellite model that dominated government satellite procurement for decades.
For Viasat's subcontractors and suppliers on the Swarm 1 delivery, the delivery order provides revenue visibility and a clear execution timeline tied to Space Force delivery requirements. Satellite supply chains are highly specialized, and suppliers who have positioned themselves in Viasat's SATCOM programs will benefit from this sustained demand. The delivery order's protected communications requirements also mean that many components must be radiation-hardened and space-qualified to standards exceeding commercial satellite applications, creating premium pricing opportunities for suppliers with these specialized capabilities.
The PTS-G program's swarm model also creates subcontracting opportunities for small businesses with relevant space component and subsystem capabilities, as prime contractors building multiple satellites in short-term delivery orders will need to rapidly scale supply chain volume. Companies with qualified space heritage components — power systems, attitude control, communications payloads, radiation-hardened electronics — should actively engage with PTS-G prime contractors as the program's satellite production rate increases over the coming years.
