Abstract: With the rapid advancement of intelligent technologies and their deep penetration into the military domain, modern naval warfare paradigms and operational models are undergoing profound transformations, driving surface naval vessels toward accelerated intelligent evolution. Focusing on key technological directions such as surface ship design and manufacturing, operational maintenance management, perception and decision-making, and information systems, this paper systematically reviews the core development trends in surface ship intelligence. It delves into the current application status and future directions of critical technologies, including intelligent design and manufacturing, unmanned/autonomous operational maintenance, integrated perception and decision-making, and systematized maritime operations. The aim is to provide theoretical support and technical references for upgrading China's surface naval vessels from "isolated point-wise intelligence" to "holistic system-wise intelligence," thereby facilitating a comprehensive leap in the intelligent capability of surface ships.
