Space Superiority Begins and Ends on the Ground

Northrop Grumman continues to push the boundaries to enable a connected future. Our ground system capabilities are connecting all domains from earth to orbit with real-time intelligence for real-time decision-making. We leverage decades of ground systems leadership in mission management and processing, missile warning and tracking, space domain awareness and the tactical edge, bringing extensive mission understanding. Through the demonstration of our end-to-end capabilities—Northrop Grumman is a ground systems provider of choice for critical missions around the globe.

Tactical Edge

Northrop Grumman develops ground-based solutions with the ability to get any data, any place, any time for any mission across the Department of Defense and the intelligence communities. Our JADC2 systems deliver information that enables decision-making for mission specific needs, and our tactical edge product line allows warfighters to be "alone and unafraid" with resiliency in any mission.

Tactical Intelligence Targeting Access Node (TITAN) Pre-prototype

The mobile system leverages commercial and military space assets to facilitate deep-sensing, reduce sensor-to shooter timelines and maximize the effectiveness of long-range precision fires.

The capabilities are part of a larger TITAN program, a scalable and expeditionary intelligence ground station that will leverage space, high altitude, aerial and terrestrial layer sensors to provide targetable data to commanders at all levels so they can quickly assess threats.

Tranche Programs

Northrop Grumman is providing the ground system support for all Northrop Grumman Tranche programs.

Tranche 1 Transport Layer (T1TL)

T1TL is part of the Space Development Agency’s low-earth orbit network designed to communicate vital information to support U.S. troops on the ground quickly and securely.

The T1TL network will deliver persistent, secure connectivity, and serve as a critical element for advancing the U.S. Department of Defense’s vision for Joint All Domain Command and Control.
