In order to understand the current status and trends of the US navy simulation training, the simulation training system is analyzed. A systematic analysis of 18 navy simulation training systems from two dimensions of physical attributes and training content shows that the US Navy is upgrading existing equipment and introducing virtual reality equipment, mainly for individual/unit training. Based on the analysis results, some suggestions are put forward, such as reasonable selection of simulation training systems, increasing the interoperability of simulation systems, and improving the evaluation methods of simulation training effect. The results show that the analysis can provide reference for our navy to carry out simulation training.
