The Department of Defense, specifically the Naval Air Warfare Center Training Systems Division (NAWCTSD), is seeking information from qualified vendors regarding the development of Cross Domain Software Solutions (CDSS). The primary objective is to identify capabilities that align with the Government's requirements for a controlled interface that facilitates the secure transfer of information across different security domains, which is critical for Live, Virtual, and Constructive (LVC) training environments. This initiative is vital for enhancing interoperability among training systems and ensuring effective command and control operations. Interested parties are encouraged to submit their qualifications and capabilities by July 15, 2025, to the primary contact, Julio Figueroa, at julio.figueroa.civ@us.navy.mil, or the secondary contact, Stephen C. Wagner, at Stephen.c.wagner10.civ@us.navy.mil.
