The Department of Defense, through the Naval Sea Systems Command, is issuing a Request for Solutions (RFS) for the Prototyping Research and Operations for Tactical Electromagnetic Warfare and Advanced Networking (PROTEAN) project. This initiative aims to address the current lack of a demonstrated electromagnetic warfare (EW) and seeker payload framework, which hinders the technical evaluation and integration of various EW solutions onto unmanned platforms. The project is critical for overcoming technical integration challenges, standardization issues, and enhancing operational effectiveness within the realm of national defense. Interested vendors must be members of the Strategic & Spectrum Missions Advanced Resilient Trusted Systems (S2MARTS) Consortium and can find more information on membership at S2MARTS.org. The response deadline for this opportunity has been extended to April 30, 2025, with inquiries directed to Judy Blanton at judith.a.blanton3.civ@us.navy.mil or Lance Buechler at lance.a.buechler.civ@us.navy.mil.
