电磁轨道炮技术是美国在“第三次抵消战略”下重点开发的关键性、颠覆性和前沿性武器系统技术,但实际上美国最早于20世纪10年代就开始进行相关研究,20世纪90年代以后逐步渐入佳境,21世纪初以来从概念研究进入到原型开发阶段。目前,BAE系统公司和通用原子公司分别牵头实施海基和陆基型号研制项目,实战型电磁轨道炮最早将于2020年左右列装。在2017财年,美国海军为电磁轨道炮、 Electromagnetic rail gun technology is the key, subversive and cutting-edge weapon system technology that the United States focused on in its “third offsetting strategy,” but in fact the United States began its research as early as the 1910s. The 20th century Gradually getting better after 90 years, since the beginning of the 21st century from the concept of research into the prototyping stage. At present, BAE Systems and General Atom respectively take the lead in the development of seabuckthorn-based and land-based model development projects. Actual combat-type electromagnetic rail guns will be outfitted as early as 2020. In fiscal year 2017, the U.S. Navy is an electromagnetic rail gun,
