Resilient MW/MT - LEO

The Space Development Agency (SDA) is developing and demonstrating the Proliferated Warfighter Space Architecture (PWSA) Tracking Layer (Project 657LEO) for Guardians across the Combat Support, Satellite Communications, Operations, and Warfighting mission areas. As a result, the Service will improve readiness and operational reach of existing force structure and continue to advance all near term effects. SDA is rapidly developing and demonstrating next generation space capabilities for the joint warfighter enabled by proliferation of satellites in Low Earth Orbit (LEO) and a new acquisition model utilizing rapid spiral development. SDA is advancing a proliferated space architecture to address a wide range of Department of War (DoW) space needs aligned with the United States Space Force Space Warfighting Framework, including advanced missile tracking and global surveillance enabling beyond-line-of-sight targeting. In coordination with Combatant Commands and other DoW Space stakeholders, SDA will orchestrate the rapid development and fielding of the Proliferated Warfighter Space Architecture (PWSA), a resilient military sensing and data transport capability via a proliferated space architecture in LEO. This program element funds the development and demonstration of space technologies to deliver Missile Warning, Missile Tracking and Missile Defense (MW/MT/MD) and Fire Control capabilities to U.S. joint warfighting forces in bi-annual tranches, which began in FY 2022. As part of the PWSA, SDA is building and fielding the Tracking Layer, using a proliferated constellation of satellites to provide resiliency through a layered sensor net to ensure space sensing necessary to respond to incoming threats. The PWSA Tracking Layer provides worldwide persistent visibility at fidelity levels which enable low-latency detection and real-time tracking to meet critical operational timelines. The total cost of the Tracking Layer Tranche 1 (TRKT1) Middle Tier of Acquisition effort is $2,841.700 million, including RDT&E and procurement of prototype units. The TRKT1 program is fully funded across the Future Years Defense Program. The total cost of the Tracking Layer Tranche 2 (TRKT2) Middle Tier of Acquisition effort is $3,965.900 million, including RDT&E and procurement of prototype units. The TRKT2 program is fully funded across the Future Years Defense Program.
