Northrop Grumman will design and build 36 LEO data transport satellites for the Space Development Agency (SDA) supporting Proliferated Warfighter Space Architecture (PWSA).
The satellites will integrate with, and expand the PWSA mesh network, utilizing high-data-capacity optical crosslinks to deliver accessible, near-real time communications to U.S. warfighters and defensive platforms operating around the globe. The design for this latest iteration, known as Tranche 2 Transport Layer Beta (T2TL Beta), builds on the 42 Tranche 1 Transport Layer (T1TL) and 14 Tranche 1 Tracking Layer (T1TRK) satellites that SDA previously announced it had awarded Northrop Grumman. The T2TL Beta space vehicles add new broadcast and tactical waveforms improving the capabilities of the overall PWSA.
“Creating a low-Earth orbit communications architecture that meets the needs of the warfighter is complex,” said Blake Bullock, vice president, communication systems, Northrop Grumman. “With Northrop Grumman's extensive military satellite communication experience and deep mission understanding, we are helping SDA make its vision a reality. Northrop Grumman said it is on track to launch its first plane of 21 space vehicles in Q4 2024. ”
