The company plans to move the manufacture of Transport Layer satellites for the US Space Development Agency (SDA) into the new facility. The company is currently manufacturing 10 Tranche 0 satellites at another facility but the 42 Tranche 1 units will be built at the new factory along with other small satellites and Cubesats.
SDA’s Transport Layer will provide military users with low-latency communication links through a resilient network of integrated capabilities from low-Earth orbit. Tranche 1 satellites are expected to begin launching in 2024.
The 20,000-square-foot low bay clean room, located on the company’s Waterton campus, in Littleton, Colorado, will feature six scalable parallel assembly lines and is configurable to host different classifications of missions concurrently.
The facility hosts dedicated testing capabilities, including thermal cycle and electromagnetic chambers, scaled to efficiently build and test satellites ranging in size from CubeSats to smallsats. The tailored fit is designed to reduce waste and optimises energy and space, supporting the delivery of 180 satellites or more per year.

Northrop Grumman has delivered major components and begun pre-launch preparations for the Arctic Satellite Broadband Mission (ASBM), a crucial effort in delivering protected satellite communications to the challenging northern polar region.

The two-satellite ASBM constellation will deliver protected SATCOM to the northern polar region and is a combined effort between the US Space Force, Space Norway and Northrop Grumman.
ASBM uses the Northrop Grumman GEOStar-3 platform, which includes the main structure and systems required to maintain operation, such as power, propulsion, communications, command and data handling and thermal control as well as guidance and navigational control. Northrop Grumman also provides the payload and ground system.
The Control and Planning Segment (CAPS) ground system was delivered to the USSF in March following successful completion of the site acceptance test and functional configuration audit/physical configuration.
CAPS is currently transitioning to the operations phase which opens the door for using the ground system for early operations with the two on-orbit operational payloads along with the capability to support the two Enhanced Polar System Recapitalization (EPS-R) payloads after the ASBM launch.
As well, integration of the EPS-R payload on ASBM-1 and ASBM-2 has finished and thermal-vacuum environmental testing on ASBM-1 has been successfully completed.
