SDA Seeks Industry Feedback on Various Tranche 3 PWSA Solicitations

The Space Development Agency (SDA) has issued multiple RFIs for Tranche 3 Tracking updates to the Proliferated Warfighter Space Architecture (PWSA), a layered network of Low-Earth Orbit (LEO) satellites that provides space-based capabilities to the joint warfighter. The T3 layer will update the PWSA’s current Tranche 2 PWSA architecture and bolster the nation’s missile defense system.

In the last week of January of this year, the SDA announced that it is seeking industry feedback on a variety of PWSA solicitations. These solicitations were focused on the PWSA’s tracking layer, which provides global indications, warning, tracking, and targeting of missile threats, and its transport layer, which ensures low-latency military data and connectivity worldwide.

Draft Solicitations for Tranche 3 Updates

Investments in space-based warfighting capabilities have become increasingly pertinent with the advent of advanced missile threats, such as hypersonic missile threats. Tranch 3 updates to the PWSA reassert the SDA’s commitment towards protecting the United States from terrestrial threats using innovative technologies.
