The Space Force now has a company to run the traffic control layer for its new military satellite data network. Viasat will build the Mission Operations Center (MOC) that ties together satellites from several vendors on the Space Data Network (SDN) Backbone, the system meant to move sensor and targeting data for the Golden Dome missile defense effort, Breaking Defense reported. Space Systems Command (SSC) announced Thursday, Nov. 5, that Viasat won an indefinite delivery/indefinite quantity (IDIQ) contract with a ceiling of $450 million to "design, field, and scale" the center. SSC made the award in what Breaking Defense described as a "partnership" with the Pentagon's Golden Dome office.
According to DefenseScoop, SSC called the IDIQ "competitive," and Viasat received an initial task order valued at $115 million to design, field and scale the MOC. The press release did not disclose where the MOC will be built.
What the $450M Mission Operations Center Will Do
The MOC will serve as the central network orchestration hub for the SDN Backbone. Breaking Defense describes that backbone as a low Earth orbit constellation SpaceX is building to provide high-speed, low-latency communications. In SSC's framing, Viasat is the integrator that makes satellites built by different companies behave like one network.
"In this role, Viasat, Inc. will serve as the network and mission system integration partner as SSC expands its open-architecture ecosystem across multiple space-segment providers," the SSC release said, as quoted by Breaking Defense.
The release, also quoted by DefenseScoop, describes the operations job: "The MOC will bring together mission integration, network operations, and data transport management across a growing multi-vendor architecture, helping SSC’s Space-Based Sensing and Targeting (SBST) portfolio field an operationally integrated capability."
According to Breaking Defense, the release lists three capabilities the MOC will give the backbone:
- Multi-vendor orchestration, which integrates disparate satellite systems into a unified communications network.
- Multi-domain joint connectivity, which supports high-speed, low-latency and cyber-resilient data paths for users across air, land, sea and space.
- Real-time priority routing, which enables dynamic data management and routing based on mission priorities through network operations infrastructure.
Breaking Defense explained that network orchestration lets data shift automatically among constellations in different orbits and down to the ground stations that support them. Data can "hop" from one constellation to another when bandwidth congestion or adversary jamming slows a link. The outlet compared the MOC to a software-run version of an old telephone exchange, where operators once patched calls together by hand and fixed them when they failed.
How the MOC Fits With SpaceX's SDN Backbone and the August Vendor Picks
The MOC award adds an operations layer on top of space-segment contracts the Pentagon has already handed out. Earlier this year the Pentagon awarded SpaceX a $2.3 billion contract to deliver a fully operational prototype of the SDN's "backbone" by the end of 2027, DefenseScoop reported. That technology is intended to enable backhaul communications across the Defense Department.
In August, the Space Force chose Amazon LEO for Government, Lockheed Martin, Northrop Grumman, Rocket Lab and York Space Systems to demonstrate ground-to-space and space-to-space data transport across vendors' systems, and to develop and field space exchange point (SEP) payloads. Because the MOC is meant to orchestrate mission systems across multiple constellations and providers, those efforts and the SpaceX backbone are the kind of systems it will have to bring together as one network.
DefenseScoop said the broader Space Data Network is expected to include a multi-orbit constellation and a hybrid architecture of military-owned and commercial payloads built by different companies, delivering high-speed data transport and tactical communications to the joint force. Breaking Defense called the backbone "the glue" connecting military, and eventually commercial, space-based sensor and communications satellites with decision-makers and weapons platforms. It said the network's near-term focus will be on supporting Golden Dome.
Lt. Col. Alexa Eggert, materiel leader for the SDN Backbone program at SSC's Space Based Sensing and Targeting Portfolio Acquisition Executive office, explained why the operations center matters to that mix. "The MOC establishes the mission operations layer needed to integrate the diverse space data transport and space exchange systems being developed across related efforts," Eggert said in a statement quoted by Breaking Defense. "By bringing the systems together in one place, it positions us to deliver a more integrated mission capability across multiple constellations and systems."
Eggert also called standing up the center "a crucial step in maturing our Space Data Network into a fully operational, multi-vendor capability," according to DefenseScoop.
Why SSC Is Betting on an Open, Multi-Vendor Architecture
The award shows how SSC appears to be structuring the program. Rather than one vendor's closed system end to end, the pieces named in the two reports are a SpaceX-built backbone constellation, exchange-point payloads from five companies, and a separate integrator, Viasat, for the operations layer. SSC's own language points the same way: the release speaks of expanding an "open-architecture ecosystem across multiple space-segment providers."
That structure gives Viasat a central position. As the network and mission system integration partner, Viasat sits between the operations layer and the space-segment providers whose systems the MOC is meant to orchestrate. The release frames the MOC as "the central integration hub for orchestrating mission systems across multiple constellations and providers," per DefenseScoop, supporting secure, resilient, high-capacity connectivity for warfighters across air, land, sea and space domains.
What It Means for Contractors
The integration layer is now taken. With Viasat holding the MOC IDIQ, companies that want work on SDN Backbone operations will likely need to approach it as a teammate or subcontractor rather than compete for the hub directly. The first task order is valued at $115 million against the $450 million ceiling, so more task orders may follow as the center scales.
Interoperability is the price of entry. SSC's description of multi-vendor orchestration and an open-architecture ecosystem suggests space-segment providers, including the five August SEP awardees, will need their systems to work with an operations center they do not own. Firms with payloads, ground stations or network software headed for the SDN should watch for interface standards and integration requirements coming out of the MOC effort.
Golden Dome money keeps flowing to connectivity. SSC made the award in partnership with the Golden Dome office, and Breaking Defense says the network's near-term focus is missile defense. Contractors following Golden Dome should treat data transport, network management, cyber resilience and priority routing as program needs, alongside interceptors and sensors.
The 2027 deadline sets the pace. SpaceX's backbone prototype is due to be fully operational by the end of 2027, and the MOC is the layer meant to orchestrate the network around it. That timeline suggests near-term demand for integration, test and operations support. Where that work will be done is still unknown, because SSC has not said where the MOC will be built.
