In order to implement real-time weapon delivery planning onborad a fighter aircraft to create a path for attacking and to realize the path design integrating flying attacking with quitting a method of weapon delivery planning was put forward.Taking a guided bomb as an example the process of fire control for the bomb the threat model of battlefield and a path-planning model were described.A model was established for calculating the key points of weapon delivery and an agorithm of quitting path-planning was given. Simulation result showed that the algorithm is feasible.
