Proliferated Space Systems

Innovation and agility rooted in unmatched mission experience.

Proliferated Space Systems

Northrop Grumman is leading in the effort to explore and prove out emerging space-based communications and missile tracking architectures – developing solutions from the spacecraft on orbit to the powerful ground processing that stitches it all together. Leaning on decades of proven, end-to-end satellite system integration and leveraging our unique mission expertise across all orbital regimes, we combine in-house capabilities and smart commercial teaming to field these critical capabilities at scale and at the speed our rapidly changing security environment demands.

A Vision for the Future

The world of military satellite communications (MILSATCOM) and space-based sensing is changing.

Adversaries are taking aim at the United States and its allies’ ability to sustain robust, space-based networks, undermining America’s ability to both protect the homeland and defend allies across the globe. Proliferated systems are a key component of a resilient hybrid architecture.

Northrop Grumman is working to build the MILSATCOM and overhead persistent infrared (OPIR) architectures of the future, which include large numbers of low-earth orbit satellites that complement more exquisite systems flying on higher orbits. Northrop Grumman is the industry leader in protected and resilient military SATCOM and is leveraging more than 40 years of mission experience to turn this concept into a reality.

Our team continues to innovate, lower costs, and break down barriers to solve tomorrow’s toughest challenges today.


Laser Communication For Tranche 1 Transport Layer Prototype Constellation

Tranche 1 Transport Layer

Northrop Grumman is under contract to deliver 42 satellites as part of SDA’s Tranche 1 transport layer. Our solution leverages a best-in-breed approach that pairs a commercial bus pairs a commercial bus with encrypted Link 16, Ka-band, and optical communications.

Tranche 1 Tracking

Northrop Grumman is under contract to deliver 16 satellites that pair the commercial bus and comms suite of our Transport Layer solution with infrared tracking payloads, enabling warfighters to maintain a high-resolution track on difficult-to-detect hypersonic targets that threaten the homeland and U.S. forces operating around the globe.

Northrop Grumman’s Hypersonic and Ballistic Tracking Space Sensor (HBTSS) satellites will provide continuous tracking and enable handoff for targeting of enemy missiles, including hypersonic threats launched from land, sea or air. HBTSS is a critical part of a future proliferated, multi-layered OPIR constellation of satellites.
