The Space Development Agency (SDA) is issuing this solicitation to establish the foundation for Tranche 1 (T1), the Initial Warfighting Capability Tranche, of the National Defense Space Architecture (NDSA). The NDSA’s operational utility is predicated on the availability of a ubiquitous data and communications Transport Layer provided by a proliferated constellation of relatively small, mass-producible space vehicles (SVs) in low Earth orbit (LEO). The Tranche 1 Transport Layer (T1TL) SVs will be similar to those currently under development for the Tranche 0 Transport Layer with targeted technology enhancements, mission-focused payload configurations, increased integration, and greater production efficiencies. The T1TL will provide global communications access and deliver persistent regional encrypted connectivity in support of Warfighter missions around the globe by serving as the backbone for Combined Joint All Domain Command and Control (CJADC2) built on low-latency data transport, sensor-to-shooter connectivity, and direct-to-weapon connectivity.

The T1TL Request for Proposal (RFP) is attached.  To receive Attachment 1 (Statement of Work and Technical Requirements Document) and the T1TL Bidder’s Library, please send an email to [email protected] with the subject line “SDA T1TL RFP Attachment Request.” Please include your organization’s CAGE code and location in your request.  Requests received from organizations that do not possess a facility clearance of at least Secret will be evaluated on a case-by-case basis.  SDA will endeavor to respond to all requests in the order that they are received and within one business day of receipt.

Note - the T1TL Industry Day Agenda with links to the video presentations is also provided.  Industry Day materials are being furnished for informational purposes ONLY.  In the event of a conflict, the text of the RFP takes precedence over any information contained in the Industry Day presentations.
