With the diversified development of combat scenarios,modern warfare is accelerating its transformation from mechanization and informatization to intelligence.Intelligent mission planning is gradually replacing traditional mission planning as the brain of unmanned swarm combat,which is the core link for effective execution of combat missions and improvement of combat effectiveness by swarms.Based on the connotation of mission planning and the characteristics of unmanned swarm combat,the research status of unmanned swarm intelligent mission allocation methods,intelligent trajectory planning methods and intelligent efficiency evaluation methods are systematically reviewed.Finally,combined with the challenges that need to be addressed in mission planning,the development prospects of future swarm intelligent mission planning methods are given.The review indicates that intelligent mission planning methods are an important factor in improving the efficiency of unmanned swarm missions.It is necessary to focus on challenges such as uncertain environments,large-scale cluster formation,rapid iteration of multi mission optimization and intelligent mission allocation and intelligent trajectory planning decoupling,in order to further enhance the level of intelligence in unmanned swarms mission planning methods.
