国防部高级研究计划局正在探索各种潜在应用的新型激光技术,但是它的主要精力则放在潜在的空间应用上,包括卫星防御和弹道导弹防御。 虽然有可能更快地用于防空和导弹防御的面基（包括陆基和水面）应用中,但是一些国防部官员和国会议员们认为:空间运载应用中最能发挥激光武器的固有优点。 这种观点反映在国防部的决定上,它将从海军“海石”高能激光计划的81财年请求的拨款中削减二千万美元,并且将给国防部高级研究计划局增加二千五百多万美元的经费,用于论证高能激光用于卫星防御的潜力。这笔饯比该局计划中这部分经费多一倍。
Defense Advanced Research Projects Agency is exploring new laser technologies for a variety of potential applications, but its main focus is on potential space applications, including satellite defense and ballistic missile defense. While it is possible to make faster use of surface-based (including land-based and surface-based) air defense and missile defense applications, some DoD officials and lawmakers believe that the inherent advantages of laser weapons are best served in space-carrying applications. This view is reflected in the Department of Defense’s decision to cut 20 million U.S. dollars from the funding requested for the FY 81 Navy’s High Energy Laser Program and to add another 2,500 to the Defense Advanced Research Projects Agency Multi-million dollar funding to demonstrate the potential of high-energy lasers for satellite defense. This amount of money is twice as large as that part of the council’s plan.
