In this system, the parent plane is responsible for carrying and launching the child plane, while the child plane is used to perform specific tasks or targets. The parent plane usually has a larger load capacity and a longer flight distance, and can carry multiple child planes for long-distance flight. When a specific task needs to be performed, the parent plane launches the child plane at the appropriate location, and the child plane performs reconnaissance, strikes or other operations in the target area.
