The combat application and related technology research of underwater drone swarm are developing rapidly. The cooperative situation generation is the basis of underwater drone swarm operation，and the important premise of cooperative decision-making and striking. In addition，the combat effect of underwater drone swarm also needs to be evaluated through the re-cognition of the battlefield situation. Based on the combat application of underwater drone swarm，this paper summarizes the needs of situation generation for underwater drone swarm， analyses the main difficulties in the process of cooperative situation generation，such as situation element representation，target recognition，situation reasoning and group recognition. Finally，this paper puts forward the technical route and implementation path，providing ideas for further and extensive research.
