Request for Information - Accelerated Development of the Second Generation Anti-Jam Tactical UHF Radio for NATO (SATURN) Enhanced Data Rate (SEDR) Waveform

***RFI RESPONSE SUSPENSE EXTENDED - DUE 5 JUNE 2026*** *** Questions closed 14 MAY 2026*** ***Amendment 2 to RFI Posted - Amendment 2 extends response and changes POC. Please send information to Capt Velia Colunga velia.colunga.1@us.af.mil and Mr. Paul Munafo paul.munafo@us.af.mil as Contract Specialist*** Amendment 1 to RFI Posted - Amendment 1 includes additional information about requesting CUI RFI Addendum and an NDA attachment. Send request for addendum and signed NDA to POCs. Additionally, Q&As from respondents are attached for post. The Air Force Life Cycle Management Center, Aerial Networks Division (AFLCMC/C3N) is conducting market research to identify sources (potential SEDR acceleration contractors) with expertise, facilities, and personnel to design, develop, and prototype key algorithms and functions of waveforms, including but not limited to the SEDR waveform. The Government is seeking sources to expand its capacity to plan, develop, evaluate, analyze, test, demonstrate, exercise and document waveform specifications. The initial waveform whose advancement would be supported by this notice is the SEDR waveform. SEDR support tasks may be assigned and cooperatively worked in parallel between C3NG government civilians, C3NG FFRDC personnel, C3NG A&AS contractors, and SEDR acceleration contractors. SEDR support tasks may include development, analysis, and test of C3NG Reference Implementation Lab (RIL) SEDR radios, to include integration of prototype code developed by one or more SEDR support task developers. SATURN Waveform specification, RIL SEDR radio prototype code and supporting documentation will be uploaded to the Department of Defense Information Repository (DoD IR) for distribution to all authorized SATURN stakeholders and radio developers. SEDR support tasks may include proprietary vendor specific radio engineering activities and implementation details. All proprietary SEDR support task work products should be identified as such and will be handled accordingly and protected from disclosure in accordance with applicable laws and regulations. Features that could be explored under the initial SEDR advancement effort may include but are not limited to: 1. Physical Layer 2. Mobile Ad Hoc Network (MANET) Features 3. Internet Protocol (IP) Interface Issues 4. Communications Security (COMSEC) 5. Transmission Security (TRANSEC) 6. Modeling and Simulation 7. Hardware Development / Prototyping 8. Information Assurance boundary issues and concerns The Government, through the RFI responses, seeks to understand vendor capabilities and experience to plan for a potential future solicitation. The attached document contains all necessary instructions for respondents.
