As one of the first directed energy weapons to be put into operational use,laser weapons have the advantages of speed of light firing,fast entry into force,high efficiency in use and strong controllability.Currently,the United States with "multi domain warfare" as its traction,and constantly strengthens the research and development and deployment of laser weapons in land,sea,air and space combat domains.This paper comprehensively analyzes and combs the top level planning and development and construction mechanism of U.S.laser weapons,and combines the development of its laser weapons technology and demonstration and verification in the past five years,and predicts the development strategy and direction of U.S.laser weapons in the coming period of time,with a view to providing certain references for the research in related fields.
