; (ii) the NASA 2014 Strategic Plan; (iii) the Aeronautics Strategic Implementation Plan; and (iv) any updates to the programs called for in the plans described in clause (i) through (iii); and (3) a level of funding that adequately supports full-scale experimentation and related infrastructure must be assured over a sustained period of time to restore NASA's capacity to see legacy priority programs through to completion and achieve national economic and security objectives. (b) National policy It is the policy of the United States to maintain world leadership in military and civilian aeronautical science and technology, global air power projection, and industrial leadership. To this end, one of the fundamental objectives of NASA aeronautics research is the steady progression and expansion of flight research and capabilities, including the science and technology of critical underlying disciplines and competencies, chief among which are computational-based analytical and predictive tools and methodologies, aerothermodynamics, flight propulsion, high-temperature structures and materials, and flight controls. (c) Establishment of programs or projects The Administrator shall establish the following programs or projects: (1) A low-boom supersonic aircraft program or project that will— (A) demonstrate supersonic aircraft designs and technologies that reduce sonic boom noise to levels that encourage the repeal of domestic and international bans on supersonic flight overland
