Description
The Space Development Agency (SDA) is seeking information to inform future solicitations and reduce risk associated with the Proliferated Warfighter Space Architecture (PWSA) architecture acquisition and integration plans. This RFI seeks industry feedback on enhancements to its baseline Tracking Layer’s Resilient MWTD mission payloads and architecture, as well as new mission capabilities that can help the PWSA provide enhanced mission performance to detect and track more challenging targets across their full flight trajectories. Additional details, mission objectives, and architecture information are available upon request. Responses to this RFI will specifically inform SDA’s scope and design of possible short-term on-orbit demonstration(s) and future Tracking Layer tranches. Following this RFI and feedback phase, SDA plans to announce a Tranche 4 solicitation that includes both production contracts and partnership opportunities for rapid prototyping and flight demonstration(s) of new mission payloads. This Request for Information consists of Controlled Unclassified Information (CUI) and a classified addendum. Interested parties must contact SDA to receive the documents. Please send an email to ussf.pentagon ussf.pentagon.sda.mesg.sda-sn-27-0003-mbx@mail.mil with the subject line “TRKT4 RFI Content Request.” Please include: • Company Name: • Cage Code: • City, State of Company location • Email address: • JWICS email: (for classified documents)
