The USCG is conducting market research via an RFI to identify commercially available off-the-shelf/non-developmental maritime navigation software that can be enhanced to modernize and eventually replace the legacy “Vega” suite across the cutter and boat fleet. Candidate solutions must integrate with existing IEC 60945 shipboard hardware without complete bridge refits, support Windows 11 Enterprise and Enterprise Linux, and provide deterministic state recovery after ungraceful power loss or reset. Required capabilities include multi-protocol sensor ingestion, data logging/forensic playback, S-57/S-63/DNC and IHO S-100/S-101/S-102/S-104/S-111/S-124 chart support, ownship dynamics, radar overlay via Furuno SDK/SSR COMRIC, and IHO S-52 human-system interface compliance. Specialized USCG mission functions include Western Rivers ATON/buoy tending/depth survey/enterprise synchronization, STEDS/encrypted AIS interfacing, blue force tracking, tactical target management, SAR pattern generation, and tactical messaging. Vendors should address architecture/OS/hardware modularity, resilient PNT and sensor fusion, EW mitigation, cybersecurity/RMF/STIG compliance, licensing, lifecycle support, and integration of custom mission modules through APIs, SDKs, or plug-ins.
