【视频】特朗普选定「金穹」导弹防御系统方案：总价约1750亿美元、任期末前投入运行
美国总统特朗普2025年5月20日在华盛顿白宫椭圆形办公室宣布，「金穹」（Golden Dome）导弹防御系统的总体方案已经选定，总造价约1,750亿美元，首笔250亿美元将列入正在国会审议的「大而美法案」，系统应在本届任期结束前全面投入运行。特朗普同时任命太空军作战部副部长 Michael Guetlein 上将为该项目的直接汇报项目经理。
特朗普说，这套系统将在陆地、海洋与太空部署下一代技术，包括天基传感器与拦截器，并与现有防御能力整合。他说：「金穹全面建成后，将能拦截从世界另一端发射、甚至从太空发射的导弹。」他表示，高超音速导弹、弹道导弹与先进巡航导弹「全都会被击落」，拦截成功率「非常接近100%」。他还说，这是完成里根总统40年前想做而当时没有技术条件的事。
特朗普介绍，Guetlein 是四星上将，曾获国防杰出服役勋章，在导弹预警技术与国防采购方面背景深厚。出席宣布的还有国防部长 Pete Hegseth 与参议员 Dan Sullivan、Kevin Cramer、Jim Banks。Hegseth 说，「金穹」是改变格局的举措，是对美国与美国人安全的世代性投资。特朗普还表示，加拿大已表达加入意愿，美方将与加方商谈，加拿大将支付其应付的份额。
「金穹」的构想源于特朗普2025年1月27日就职首周签署的行政令，该命令要求为美国建设新一代导弹防御盾。项目成本存在不同估算：国会预算办公室此前估算，仅其中的天基拦截器部分，未来20年的成本就可能高达约5,420亿美元，远高于白宫给出的总价，项目的最终造价与时间表仍取决于国会拨款。白宫官方发布了这次宣布的全程视频。（来源：白宫）
[Video] Trump Selects Design for $175 Billion Golden Dome Missile Shield, to Be Operational Before End of His Term
President Donald Trump announced in the Oval Office of the White House in Washington on May 20, 2025, that an architecture had been officially selected for the Golden Dome missile defense system, at a total cost of about $175 billion, with an initial $25 billion to be included in the 'One Big Beautiful Bill' then before Congress, and that the system should be fully operational before the end of his term. Trump also appointed Gen. Michael Guetlein, the Space Force's vice chief of space operations, as the direct reporting program manager for the effort.
Trump said the system will deploy next-generation technologies across land, sea and space, including space-based sensors and interceptors, and will integrate with existing defense capabilities. "Once fully constructed, the Golden Dome will be capable of intercepting missiles, even if they are launched from other sides of the world and even if they are launched from space," he said. Hypersonic, ballistic and advanced cruise missiles "will be knocked out of the air," he said, putting the success rate at "very close to 100 percent," and said the project completes the job President Ronald Reagan started 40 years ago, when the technology did not exist.
Trump described Guetlein as a four-star general and recipient of the Defense Distinguished Service Medal, with an unmatched background in missile warning technology and defense procurement. Defense Secretary Pete Hegseth and Senators Dan Sullivan, Kevin Cramer and Jim Banks attended the announcement. Hegseth called the Golden Dome a "game-changer" and a "generational investment in the security of America and Americans." Trump also said Canada had called and wants to be part of the program, that the two sides would talk, and that Canada would pay its fair share.
The Golden Dome stems from an executive order Trump signed on January 27, 2025, in his first week back in office, directing the construction of a next-generation missile defense shield. Cost estimates differ: the Congressional Budget Office has estimated that the space-based interceptor portion alone could cost as much as about $542 billion over 20 years, far above the White House's total figure, and the program's final cost and schedule depend on congressional appropriations. The White House released the full video of the announcement. (Source: The White House)
