Mines are one of the most cost-effective and moderated weapon systems that are easy to deploy, but difficult to clear. Not only has the development of the mine countermeasure (MCM) underwater unmanned vehicle (UUV) improved cost-and time-effectiveness in operation, but also it has avoided unnecessary human casualties.In MCM UUV operations, technical challenges, such as detection, classification and neutralization of mines, and vehicle management operations, arise from the incapacity of detection sensors, data-processing power. Due to the small volume capacity, decisionmaking processing and mine-clearing operations are insufficient for safe mine countermeasure warfare operations. Larger displacement UUVs must be integrated into new platform designs so that they can be a viable organic asset.Realization of the full potential of the UUV as a truly autonomous undersea vehicle (AUV) in warfare will begin with a transition to a large displacement vehicle. In case we try to make a larger and heavy UUV system, we still encounter various problems, including vehicle operational time and speed at sea, in addition to vehicle and mission management algorithms with appropriate hardware configurations. In this work, we suggest a larger diameter of the MCM UUV with hybrid power, including the basics of artificial intelligence applied expert systems integrated into the MCM mission management systems.Keywords: mine countermeasure warfare, large diameter unmanned underwater vehicle, artificial intelligence, hybrid power operation, mission management

Abstract-A conceptual design is proposed for an effective mine countermeasure (MCM) system, which consists of three unmanned underwater vehicles (UUVs) and 10-20 small charged deliverable vehicles. New underwater optical communication systems are introduced to improve onboard mine reconnaissance and decision making with the key technologies focused on system and communication efficiency, capability of data processing, and cost-effectiveness of MCM systems. The proposed UUV MCM system is cost-effective due to adapting disposable mine neutralization instruments, upgrading data process units, and configuring optical communication systems between heterogeneous underwater and surface vehicle units in operations. At the same time, efficient and reliable underwater optical and electromagnetic wave communication systems are also introduced and analyzed for future system applications.Index Terms-Conceptual system design, mine disposal system, system effectiveness, unmanned underwater vehicle (UUV) technology.
