About this file
This file is a Questions and Answers document for the Saturn Enhanced Data Rate (SEDR) Request for Information (RFI) issued by the Air Force Life Cycle Management Center, Aerial Networks Division (AFLCMC/C3N). The Q&A clarifies key aspects of the procurement strategy and timeline. The response deadline has been extended to May 22, 2026, at 1300 EST, with questions due by May 7, 2026. The current SEDR Development RFI is entirely separate from a December 2025 RFI focused on porting an existing waveform specification into vendor radios; the December RFI is no longer under evaluation and will not receive additional Q&A responses.
The Government's strategy has evolved since an August 2025 posting that addressed porting the SEDR waveform to vendor radios. The new approach accelerates waveform development by leveraging industry expertise in collaboration with a Federally Funded Research and Development Center (FFRDC). Industry partners will assist in reviewing existing SEDR waveform work and recommending additions, modifications, and optimized approaches to ensure portability. The Government seeks vendors to help define a Minimum Viable Product (MVP) to enable rapid initial porting with iterative waveform upgrades released over time. The Government plans to transition this accelerated SEDR development RFI into a formal RFP with associated funding alignment.

Sheet1 Saturn Enhanced Data Rate (SEDR)
RFI SEDR Development
| Question | Gov Response |
| Is there any possibility that the response deadline can be extended beyond 20 April? | Response date will be extended to be due No Later Than (NLT) 1300 EST 22 May 2026. Questions will be extended to be due NLT 7 May 2026. |
| Could you briefly explain the relationship between this RFI and the December RFI? Is it only that this RFI is a sources-sought for the development of the SEDR waveform, while the first RFI was a sources-sought for porting of the waveform? Or are there other relationships or differences we should be aware of? | These are entirely separate RFIs. This RFI is based around development and the capabilities concerning further creation of the waveform. RFI in December was centered on taking a finished specification and porting it into existing radios. |
| Is the first RFI still under evaluation and/or will there be Q&A related to our December response? | The December RFI is no longer under evaluation. |
| I recall a similar notice being posted around August of last year and wanted to follow up to better understand how the requirement has evolved. Specifically, are there particular capability gaps or challenges that prompted the reposting? | The previous posting from August 2025 focused specifically on porting the SEDR waveform onto a vendor radio. Since then, the strategy has evolved. The Government has decided to accelerate the development of the SEDR waveform by leveraging industry expertise to assist with its refinement. |
Under this new approach, industry partners will collaborate directly with a Federally Funded Research and Development Center (FFRDC). The objective is to review the existing work on the SEDR waveform and recommend additions, modifications, or optimized approaches to ensure the waveform is readily portable. As part of this development effort, the Government is looking for vendors to help define a Minimum Viable Product (MVP). This will allow the Government to port an initial version as quickly as possible, with subsequent waveform upgrades released iteratively over time.
Additionally, are there any current plans to align funding with this effort or transition it toward a formal RFP? Yes, the Government plans to transition this accelerated SEDR development RFI into a formal RFP.
