GHOST-R: The Space Force’s New Watchers for Geosynchronous Orbit
Northrop Grumman and True Anomaly will build GHOST-R prototypes to inspect satellites 22,000 miles up. What is known, what is not, and how it feeds RG-XX.
“Space is becoming more congested and contested every day,” a Northrop Grumman executive said in September. In geosynchronous orbit, about 22,300 miles above Earth, the Space Force wants a cheaper, larger fleet of satellites to keep watch. On 18 September, Space Systems Command and the Defense Innovation Unit (DIU) announced prototype contracts to Northrop Grumman and True Anomaly under a project called GHOST-R, short for Geosynchronous High-Resolution Optical Space-Based Tactical Reconnaissance.
According to the command, GHOST-R uses “commercially developed space vehicles, buses, and electro-optical payloads to deliver high-resolution space-to-space imagery for characterizing resident space objects” in geosynchronous orbit (GEO). In plain terms, these are satellites built to photograph other satellites.
What the contracts cover
Neither the Pentagon nor the two companies has disclosed what the contracts are worth. The table gathers what officials and the companies have said publicly.
| Item | What has been said | Source |
|---|---|---|
| Builders | Northrop Grumman and True Anomaly, one prototype approach each | Space Systems Command |
| Mission | High-resolution imagery of objects in GEO, plus weekly observations of target satellites during demonstrations | SSC, Air & Space Forces Magazine |
| Schedule | Launch directly to GEO by 2028; government-owned, government-operated missions by 2029 | SSC |
| Northrop design | ESPASat-L bus, described as “the size of a small suitcase,” with optical payloads from TRL11 of Irvine, Calif. | Breaking Defense, Air & Space Forces |
| True Anomaly design | Jackal autonomous orbital vehicle, Mosaic command-and-control software and a rendezvous and proximity operations sensor suite | DefenseScoop |
| Contract value and funding | Not disclosed; an SSC spokesperson said the money did not come from the Andromeda contract pool | Breaking Defense |
| Follow-on program | RG-XX, the planned successor to the GSSAP inspection satellites | Breaking Defense |

Two very different builders
Northrop Grumman is the incumbent. It is the prime contractor for the Geosynchronous Space Situational Awareness Program (GSSAP), whose first satellites launched from Cape Canaveral on 28 July 2014, according to the Space Force fact sheet. Those satellites fly near the geosynchronous belt and can perform rendezvous and proximity operations, maneuvering close to an object of interest to characterize it. Northrop said its GHOST-R prototype “will provide commercial augmentation for existing space domain awareness systems, enabling the Space Force to operate a hybrid constellation architecture.” Defense News reported that the company described an “accelerated 24-month timeline” for the build.
True Anomaly is a four-year-old company, Defense News noted, and both firms are already under contract to develop space-based interceptors for the Golden Dome missile defense initiative. True Anomaly says a single Jackal “is designed to surveil dozens of satellites, investigate anomalies on friendly assets, and maintain custody of high-value targets across multi-year missions.” Jackal is being tested in the Space Force’s Victus Haze demonstration, where, according to the company, it approached a Rocket Lab-built satellite, imaged it and conducted a “space-to-space pursuit.” Company operators will fly Jackal alongside Space Force crews at first, then hand it over as a government-owned asset for RG-XX, the company said.
From GHOST-R to RG-XX
GHOST-R is a feeder for a much larger effort. In April 2026, Space Systems Command picked 14 companies for Andromeda, a contract vehicle for space-based surveillance satellites. In May the service raised its ceiling from $1.84 billion to $6.24 billion, citing what it called “the escalating threat environment projected for CY 2030+,” Breaking Defense reported.
- RG-XX: maneuverable reconnaissance satellites to replace GSSAP; $355 million requested for fiscal 2027 and $2.8 billion over five years, with launches in three increments from early fiscal 2029 to late fiscal 2030 (budget documents, via Breaking Defense).
- SG-XX: wide-field surveillance satellites to replace the classified SILENTBARKER constellation; $370 million requested for fiscal 2027, with a first launch planned in fiscal 2030.
- GHOST-R: DIU’s stated goal was a price point even lower than RG-XX’s, according to Breaking Defense.
The companies must also present a plan to scale their designs into a full constellation that can track all publicly catalogued objects in GEO, Air & Space Forces Magazine reported. “Successful prototypes will have a direct path to transition into the program of record,” said Col. Bryon McClain, acting portfolio acquisition executive for space combat power.
The push has a stated military purpose. “To be able to negate threats in space, we must be able to find, fix, track, and target those threats,” Gen. Stephen Whiting, head of U.S. Space Command, said on 16 September. “Targeting in the space domain is maturing, but it still has a long way to go.” Breaking Defense noted that the Space Force has raised concerns about Chinese programs with similar close-approach capabilities, and that the United States recently acknowledged it has stationed weapons in space without giving details.
Why it matters
Peter’s World analysis, based on the sources cited in this article.
Today, GSSAP satellites carry the inspection mission in GEO, and both U.S. Space Command and the companies involved have said more capacity and maneuverability are needed. GHOST-R tests whether small commercial spacecraft can do part of that job at lower cost and in greater numbers. If they can, the Space Force gains more eyes on rival satellites and a faster way to check its own when something goes wrong.
The same tools cut both ways. A satellite that can approach, photograph and follow another spacecraft is also the kind of capability the Space Force says it worries about in Chinese hands. In our view, that makes the program as much about norms of behavior in orbit as about hardware, and it could draw scrutiny from allies and rivals alike.
The open questions are basic ones: what each prototype costs, who is paying, and whether a startup’s hardware and a prime’s suitcase-sized bus can both deliver on a two-year schedule.
What to watch: disclosure of contract values, the first RG-XX task orders under Andromeda, results from Jackal’s Victus Haze mission and the fiscal 2027 budget fight over space surveillance money.
