WASHINGTON — The U.S. Space Force awarded Northrop Grumman a $398 million contract to build a prototype communications satellite intended to demonstrate anti-jamming technologies for military operations in contested environments, the Space Systems Command said May 15.
The contract supports the program known as Enhanced Protected Tactical Satellite Communications-Prototype, or Enhanced PTS-P, part of a broader effort to develop more resilient satellite communications systems capable of operating under electronic warfare and cyber attack conditions.
The satellite is scheduled to launch no earlier than 2030, according to the Space Systems Command.
Northrop Grumman designed the spacecraft using its ESPAStar-HP satellite bus, a platform designed for national security and commercial missions.
The Enhanced PTS-P effort is focused on validating anti-jam and cyber-resilient technologies that could support future procurements of protected military satellite communications. The demonstrations are centered on the Protected Tactical Waveform, or PTW, an encrypted communications technology designed to maintain connectivity when adversaries attempt to jam, intercept or disrupt satellite links.
PTW uses rapid frequency hopping, encryption and advanced coding techniques intended to make transmissions more difficult to detect or interfere with. The demonstrations are expected to assess how the technology performs in orbit and how it integrates with military ground systems and user terminals.
Northrop Grumman previously received prototype contracts under the PTS program and completed critical design reviews in 2021.
Separately, Boeing developed a hosted payload version of PTS-P integrated onto two Wideband Global Satcom satellites already built for the Space Force and projected to launch in the coming years.
The Pentagon has increasingly emphasized resilient communications architectures as military planners prepare for scenarios in which U.S. satellites could face sustained electronic and cyber attacks.
“Enhanced PTS-P represents another important step in delivering more resilient, protected communications capabilities to the joint force,” Erin Carper, acting Space Force portfolio acquisition executive for satellite communications and positioning, navigation and timing, said in a statement.
Carper said the demonstrations would help inform future protected satellite communications developments.
A move to fund prototype demonstrations follows the Space Force’s decision in June 2025 to terminate a previously planned $2.4 billion follow-on procurement for a larger protected tactical communications constellation.
According to Space Force budget documents submitted with the fiscal 2027 budget request, the PTS program is pursuing a “multi-phase strategy” aimed at incrementally deploying and evaluating prototypes rather than committing to a large-scale procurement upfront.
The budget documents said the service plans to proceed with both free-flyer and hosted payload demonstrations to support operational testing, training development and potential early operational use of the prototype systems.
