Abstract: Studying the strategic system of the US defense industry, especially the layout and trends of the defense industry strategies of the Trump administration 1.0 and the Biden administration since the great power competition, is helpful to deeply understand, systematically grasp, and comprehensively evaluate the construction and development of the US defense industry. The content analysis method and comparative research method are adopted to study the strategic documents of the US defense industry, depict the system layout and internal logic of the US defense industry strategy, and condense the focus of the Trump administration 1.0 and the Biden administration. This paper shows that the US defense industry strategic system is divided into three levels from top to bottom: the highest-level strategy, the dominant strategy, and the supporting strategy. The Trump administration 1.0 focused on strengthening the renewal of military capabilities to cope with the challenges of great power competition, enhancing nuclear deterrence and defense with the promotion of nuclear weapon modernization as a breakthrough, and deepening the governance of the defense industry with the promotion of defense acquisition reform, while the Biden administration mainly focuses on high-tech military, iterative nuclear forces, resilient supply chain and cooperation with Allies. Based on the layout and trends of the US defense industry strategic system, this paper predicts the possible strategic priorities of the Trump administration 2.0, and proposes insights and experiences that are adapted to our national defense science and technology industry development plan, providing a reference for the construction of our national defense science and technology industrial system.
