Based on high-end warfare, the type of low-cost unmanned aerial vehicle(UAV) swarms and their takeoff method suitable for the current development of our military are studied, as well as some ideas are provided for enhancing the current UAV swarms combat capability of our military. Firstly, it is introduced that UAV swarms must have the ability to long-range combat, the cost situation of several low-cost UAVs in the US military and the current technol-ogical status of UAV powerplants are analyzed. Secondly, three takeoff methods that can be used for UAV swarms are compared, the gaps in key technologies of multi-UAVs container launching system at home and abroad are analyzed, with thinking and learning from foreign UAV examples. Finally, it is recommended to use medium fixed-wing UAV with a takeoff weight exceeding 150kg and foldable wings as the aircraft platform for domestic UAV swarms, by solving key technologies such as the clutching of propeller and piston engine outside the launching container , and the unfolding of folding wings driven by motors, the launching efficiency of multi-UAVs container launching system for UAV swarms can be improved.
