Research on dynamic response and damage load is of great significance, including three aspects： assessment of ship structure＇s damage resistance, and mechanism of ship structure subjected to underwater explosion the assessment of warhead lethality of underwater weapons, the the prediction of warship survivability. The load characteristicsand ship response as well as the damage mechanism are important parts in the research field. In this paper, the process of underwater explosion, the explosion load classification, and the load characteristics are introduced. Based on damage types of ship under different types of load, the classification of underwater explosion, the dynamic response process, and the damage mechanism are analyzed in detail. The current research methods and development tendency about ship re- sponse and damage under underwater explosion are reviewed. Finally, some suggestions and prospect are offered for the research on response and damage of ship subjected to underwater explosion load.
