The Space Development Agency (SDA) released a final request for proposals for the Tranche 3 Program Integration (T3PI) effort of the Proliferated Warfighter Space Architecture (PWSA). This solicitation seeks industry proposals to provide systems engineering and integration activities supporting the T3 program, which will extend the PWSA through the acquisition and integration of the next generation of space vehicles (SV) and associated ground segment (GS) elements.

Proposals must facilitate the delivery of T3 Tracking, T3 Transport, and T3 Custody Layer, integration with the PWSA ground and user segments, and advancement of the operational PWSA. The T3 Custody Layer is an envisioned future layer of the PWSA that would add the capability of continuous custody of target tracks.

SDA’s T3 programs will provide sustained capability with advances over Tranche 2 in capabilities such as coverage, sensitivity, and accuracy of missile warning, tracking, and defense capabilities; coverage, resilience, and capacity of tactical data links; position, navigation, and timing (PNT) resilience, accuracy of PNT solutions, and distribution of PNT solutions to users; continuous custody of target tracks and mission and network management performance and responsiveness enabled by autonomy.
