To improve the support power for unmanned underwater vehicle (UUV) and to accelerate the forming of UUV combat effectiveness, design training and examining system about military UUV support. Based on simulation technology and carrying out training and examining about the process of technical preparation for UUV support in the way of combining the benefits of virtual environment and real-equipment training. Analyze the function and characteristics of the system, study its hardware and network structure and the method of solid modeling. The results show that the system can greatly improve the efficiency and quality of the train and examination for UUV support, implement the information management of the whole process at the same time, lay a foundation for optimizing support procedures, and provide reference for other equipments support training and examining.
