The Department of Homeland Security, specifically the U.S. Coast Guard, has issued a Request for Information (RFI) regarding engineering and sustainment support for the Sea Commander (SC) and Maritime Communication Controller (MCC) systems utilized on National Security Cutters (NSCs). The RFI aims to assess industry capabilities to provide essential logistics, engineering tasks, and training to ensure the optimal availability of these critical systems, which process real-time tactical data and manage radio frequency signals. Interested vendors are encouraged to submit their responses electronically, adhering to the guidelines provided, while noting that the U.S. Government will not cover any costs incurred in response to this RFI.
