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)

Northrop Grumman is supporting the U.S. Army’s Tactical Intelligence Targeting Access Node (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.


The TITAN pre-prototype is a mobile, semi-autonomous system that leverages commercial and military space assets to facilitate deep-sensing, reduce sensor-to shooter timelines and maximize the effectiveness of long-range precision fires.

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.

Tranche 1 Tracking Layer (T1TRK)

T1TRK’s purpose is to detect, identify and track hypersonic weapons and other advanced missiles from their earliest stages of launch through interception.

Once deployed in 2025, the T1TRK satellites will operate in up to four low-Earth orbital planes, interconnected with T1TL satellites. Each will feature a wide field-of-view infrared sensor, three optical communications terminals, and a Ka-band payload for communications.

False Track Reduction Machine Learning

Northrop Grumman is addressing one of the Space Force’s top priorities assessing thousands of emerging threats in space each month. This concept leverages machine-learning technology and operational data archives Space-Based Infrared Systems (SBIRS) historical real and false track data to reduce current false track rates by 70 percent.

A panel chaired by Lt. General Michael A. Guetlein, first commander, Space Systems Command, selected this project as the winner out of more than 80 entries. This will be one of the most impactful operator-focused solutions the missile-warning system has seen in more than 20 years.
