美国国防部正在实施一项创新的国家航空航天计划,以协调国防部下属军事单位和机构在高超声速推进、进入太空的下一代飞行器和未来航天器领域的研究活动。由于上述领域对美国防部未来作战极为重要,因而美国的国防预算将扩大对与高超声速和航天有关的技术的投资力度。为此,美国防部在2004财年预算申请中,已提出拨款近10亿美元用于上述领域,这一数字比2003财年提高了1.5亿美元,而且预计未来美国防部会保持这一投资力度。下一代巡航导弹、攻击机和运载火箭有望对未来战争产生革命性的影响。然而,美国防部内部在促进这些技术成熟问题上尚有不一致的思路,因而应该确定清晰和比较现实的目标,促进合作,保证投资支持的连贯性。
The United States Department of Defense is implementing an innovative national aerospace program to coordinate research activities conducted by Defense Ministry military units and agencies in hypersonic, space-entering next-generation spacecraft and future spacecraft. As the above-mentioned areas are extremely important to the future combat operations of the U.S. Defense Department, the U.S. defense budget will expand investment in hypersonic and space-related technologies. To this end, the U.S. Department of Defense has proposed that nearly $ 1 billion should be allocated for funding in the 2004 fiscal year budget, which is an increase of $ 150 million over the 2003 fiscal year. And it is expected that the U.S. Defense Department will maintain this investment in the future . The next generation of cruise missiles, attack aircraft and launch vehicles are expected to have a revolutionary impact on the future war. However, there are inconsistencies in the promotion of these technological maturities within the U.S. Department of Defense. Therefore, clear and realistic goals should be established to promote cooperation and ensure coherence in investment support.
