Space Force Eyes Up to Five Cislunar Seed Satellites for Late-2029 Launch

The Space Force wants a small batch of satellites working between Earth and the Moon by 2031, and it is asking industry to show it can build them fast. In a Nov. 2 industry notice, the service said it is “notionally interested” in launching up to five spacecraft to cislunar space to inform the acquisition strategy for a future Cislunar Space System operating beyond geosynchronous orbit, Air & Space Forces Magazine reported. The satellites should be ready to launch by late 2029, with initial operations by 2031.

The notice says the service could award up to five contracts and could begin funding initial design work as soon as early 2027. No contracts have been awarded yet.

Five Seed Satellites for a Future Cislunar Constellation

The Space Force frames the effort as a starting point, not a finished architecture. “These vehicles may serve as seed vehicles that will inform the acquisition strategy for a potential future proliferated cislunar constellation,” the notice states. It adds: “The government is looking for information on industry’s ability to provide a rapid, low-risk solution.”

The notice does not spell out which payloads the satellites would carry. Officials have said they are most interested in space domain awareness, positioning, navigation and timing (PNT), and communications in the cislunar regime. The notice does list two hardware and software areas. The service wants satellites with propulsion systems that can handle its station-keeping requirements as well as orbital transfers, and it wants information on AI and compute capabilities that can support long-duration autonomous operations.

Those requirements follow from the physics of the region. Cislunar space covers hundreds of thousands of kilometers, and its volume is 1,728 times that of geosynchronous orbit. Spacecraft there contend with the combined gravity of the Earth and the Moon and with unpredictable orbits that demand constant station-keeping. The region also lacks its own PNT grid; the National Geospatial-Intelligence Agency is among the offices working to build that framework.

Why the 2029 Deadline Favors Off-the-Shelf Hardware

Maj. Gen. Stephen Purdy, the Space Force’s portfolio acquisition executive for advanced programs, has made clear the service wants mature technology rather than new research. “We’re looking for existing commercial or near-commercial means, non-developmental solutions, hardware with actual relevant evidence behind it, software that doesn’t need a huge amount of work … and ground systems,” Purdy said. “This isn’t a four- or five-year science project. This is about getting capability out soon.”

The Nov. 2 notice builds on plans Purdy laid out at AFCEA’s Space Industry Days conference on Oct. 21. There, he said the Space Force would release two requests for information “imminently,” according to Air & Space Forces Magazine’s Oct. 26 report. The first calls for existing commercial technology that can be ready to launch by 2029. The second seeks AI and autonomous processing for spacecraft operating in cislunar space. Purdy described the goal as “a fully autonomous system out there at cislunar that’s able to handle all its hardware faults, all its processing, all the sensor activities.”

The Defense News reported that the service aims to field initial capabilities by September 2029, the end of fiscal year 2029. It said the first RFI covers spacecraft, sensors and related systems for space domain awareness, PNT systems for operations beyond traditional Earth orbit, and the ground infrastructure that connects them.

Separately, the Space Force is working with the Air Force Research Laboratory and SpaceWERX on an industry challenge called Lunar Prime, aimed at its less mature technology and research needs. That effort has $30 million in funding and targets flight demonstrations within two years of contract award.

How Cislunar Went From Off-Limits to a “Warfighting Domain”

The pace marks a sharp turn. Purdy said that as recently as January he was told to stay away from the subject. “There was no talk of cislunar, and basically I was told, ‘Don’t talk about cislunar, and stop getting into it,’” he said at the Oct. 21 conference.

Now, Defense Secretary Pete Hegseth, Chairman of the Joint Chiefs Gen. Dan Caine and a December 2025 executive order from President Donald Trump all stress cislunar operations and call for more investment, according to Air & Space Forces Magazine. “I’ve got the Secretary of War and the Chairman of the Joint Chiefs full on stating in public: ‘This is a warfighting domain,’” Purdy said.

Earlier in 2026 the service created a Cislunar Coordination Office inside Purdy’s portfolio to craft a technology roadmap and a future space architecture. Led by Jaime Stearns, the office has since refined that roadmap, built strategies for mission areas such as space domain awareness, communications and lunar navigation, and drafted a list of high-priority unfunded requirements. Purdy said that list includes relatively low-dollar “ticky-tacky” efforts that could help the service make real progress.

China’s lunar program is a major driver. Beijing has a cislunar roadmap of its own, has landed several uncrewed spacecraft on the lunar surface and plans a crewed Moon mission by 2030. Its plans also include work on lunar PNT models within the next 10 years and an international lunar research station. “They’re not planning for a one-off demo,” Purdy said. “They are planning for sustained activity.”

What It Means for Contractors

The Cislunar Space System notice is an early, low-commitment signal, but its timeline is tight. Firms that want one of up to five seed-vehicle contracts should expect to show flight-proven or near-flight-ready buses, propulsion that can manage both station-keeping and orbital transfers, and onboard compute that can run for long periods without ground intervention. With design funding possibly starting in early 2027 and launch readiness due in late 2029, the service is effectively screening for vendors with hardware already on the shelf.

Software firms have a separate path. The planned RFI on AI and autonomous processing targets fault handling, data processing and sensor management for spacecraft too far away for constant ground control. Companies working on lunar navigation and timing may also find openings, since the region has no established PNT grid and the Space Force lists PNT among its priorities.

Smaller and earlier-stage firms should watch Lunar Prime. Its $30 million budget and two-year demonstration target suit companies that need flight time before they can compete for operational work. Contractors should also track the Cislunar Coordination Office’s unfunded-requirements list, which Purdy said includes relatively low-dollar efforts.
