Under the background of emerging engineering and innovation in national defense technology， the society has put forward new requirements for the cultivation of talents in national defense science and technology engineering. The previous talent cultivation model for national defense science and technology engineering has problems such as a single professional curriculum system， insufficient practical and innovative abilities of students， and insufficient emphasis on national defense education. In response to the problems， innovative ideas have been proposed： firstly， integrating international thinking， eliminating disciplinary boundaries， and innovating teaching methods to accelerate the national defense oriented updating of teaching content； secondly， stimulating innovation potential and collaborating with military enterprises to cultivate students’ practical abilities in national defense engineering； thirdly， cultivating the roots of patriotism and imparting knowledge of national defense to deepen ideological and political education for the country and the people. The reform of excellent talent training mode for national defense science and technology engineering in the new era is of great significance for promoting modern military technology innovation， cultivating excellent military science and technology talents in all aspects， and strengthening national defense security.
