Based on SBIR/STTR projects,an analysis of the development of laser weapons in the United States is conducted in this paper.By reviewing publicly available SBIR/STTR projects from 2016 to 2023,a total of 98 laser weapon related technologies are summarized and selected.Combined with US military testing and integration reports,the analysis indicates that Acquisition,Tracking,and Pointing(ATP)related technologies,laser related technologies,and transmission/environmental measurement are the focal points of the US laser weapon system development.In depth analysis of the project metrics are also conducted in relation to publicly known U.S.laser weapon projects,with a focus on submarine based laser weapons and U.S.LLD laser weapon system metrics.Through the tracking and analysis of SBIR/STTR laser related projects,the development strategy and approaches to technical issues of US laser weapons are summarized,providing information support for the development and problem solving solutions of relevant technologies in the country.
