N在长达五十余年的冷战风云岁月中,美国U-2高空侦察机必然是每一个研究冷战史的史学家们都无法避开的“重要角色”。即使是3倍音速的“黑鸟”服役后,U-2依然活跃。现在,不妨让我们回到50多年前的1956年1月,那一年,U-2刚刚做好服役前的所有准备。而此前的测试飞行证明,U-2达到了1954年所制定的全部设计指标:4747干米的航程足以飞越任何大陆,21946米的飞行高度令当时任何一种防空武器都无法企及,再加上那个精致的照相机镜头——U-2踌躇满志,等待一显身手。 In more than 50 years of cold war era, the U.S. U-2 reconnaissance aircraft must inevitably be “an important role” that every historian studying the history of the Cold War can not avoid. U-2 is still active even after 3x speed of “Blackbird” is in service. Now, let us return to January 1956, more than 50 years ago, when U-2 had just completed all the preparations before service. Previous test flights proved that the U-2 reached all the design targets set in 1954: the 4747-kilometer flight was enough to fly over any continent, and the flying height of 21946 meters made it impossible for any one type of air-defense weapon at the time. That exquisite camera lens - U-2 smug, waiting for a show of skill.
