In view of the influence of the next generation air combat system projects in the United States and Europe on the development and construction of target drone， this paper analyzes the development situation and main system composition of the next generation air combat system， and puts forward the typical characteristics of the sixth-generation manned fighter aircraft as the core element and manned/unmanned aerial vehicle group cooperative operation as the main combat form. Based on the new characteristics of the next generation air combat system and its traction effect on the development of target drone， the development trend of target drone is analyzed from the aspects of target drone simulated target， application scenario， cost and performance， target drone generation mode and combat potential development.It also puts forward the idea of developing and constructing target drone to simulate next generation air combat systems.
