The US Coast Guard requires system engineering and sustainment services for the Sea Commander (SC) system, which provides real-time tactical data processing and weapons integration aboard National Security Cutters. The contractor must support logistics, engineering tasks, and training to maximize system availability. Lockheed Martin is the sole source possessing the necessary engineering and technical data for procurement, installation, and training. No specific timelines, budget amounts, or performance location are mentioned in the description. This opportunity is for a sole-source sustainment contract supporting existing USCG assets.
