To avoid technological surprise from outside and to create technologicalsurprise against rivals, the US DARPA promotes the emerging science and technology innovations, playing special roles as "science and technology vanguard" in the U.S. national security system. Facing the tides of the new scientific and technological revolutions, the development of science and technology, especially, the technologies of subversive nature, one sees opportunities and challenges with respect to the national security. In view of the science and technology's impacts on the national security, we should foresee the development of the emerging science and technologies, further improve the technology support system for the national security, and makea full use of the science and technology innovation as the dual engine of the economic and social development and the national strategic security.
