To understand the status and development trend of simulation-based training in the U.S. Navy, the existing simulation training systems are analyzed. Based on the analysis results of 18 naval simulation training systems from physical attributes and training contents, it is found that the U.S. Navy has been upgrading old trainer and introducing virtual equipment for individual/unit training. And some suggestions are put forward—Chinese Navy should use simulation-based training systems based on training objective, increase the interoperation of simulation-based training system, and improve measures of performance in simulation-based training systems. These results can provide reference for simulation-based training in Chinese Navy.
