Laser-guided weapons have been widely used in combat,and their precision characteristics are outstanding for striking important military targets such as bridges.Each type of bridge has different load transfer methods and different weak points.A typical bridge is selected for stress analysis,and a targeting point for laser-guided weapons is selected based on curve fitting.Combining the aircraft assault angle,the indicator safety indicating range and “shooting” tactics,an application method of air-to-ground laser-guided weapons against the bridge is proposed.This study can not only serve as a theoretical reference for air-to-ground attack bridge operations,but also provide a theoretical basis for the allocation of air defense forces to important targets of river-sea bridge.
