2008年2月21日,美国防部宣布,美海军在西北太平洋上发射一枚“标准”3Ⅰ导弹摧毁了一颗失控的美间谍卫星。这次美国一反常态地对拦截行动进行了高调宣传,引起了世界舆论的广泛关注。此次事件中,人们不仅对这颗神秘的卫星和拦截武器充满好奇,也为美国此举的深刻动机深感困惑。 On February 21, 2008, the U.S. Defense Department announced that the U.S. Navy launched a “standard” 3i missile on the northwest Pacific Ocean and destroyed a U.S. spacecraft that was out of control. This time, the United States unannounced its high-profile propaganda on interceptions and aroused the widespread public concern in the world. In this incident, people are not only curious about this mysterious satellite and interceptor weapons, but also deeply confused by the profound motive of the U.S. move.
