The Department of Defense, through the Marine Corps Systems Command, is conducting market research for a Digital Radio Head Interface (DRHI) as part of its Modular Advanced Radio Architecture (MARA) initiative. This Request for Information (RFI) seeks to identify potential commercial suppliers capable of providing a radio system that adheres to industry standards such as CMOSS and SOSA, with specific requirements related to frequency ranges, power levels, interfacing capabilities, and device dimensions. The MARA system is crucial for enhancing command and control, communications, and other warfighting functions, primarily serving military occupational fields including infantry, communications, and fires. Interested vendors must submit their responses by February 14, 2025, and are encouraged to reach out to the designated contacts, Kirklyn Rutland and Kathryn E. Hurd, for further information and guidance on classified submissions.
