1964年7月25日,美国总统林登·约翰逊宣布开展一项新型飞机的研制,这种高速飞机将用于深入敌方领土进行照相侦察,将使用最复杂的电子设备和监视系统,其飞行高度和速度将使其它飞机望尘莫及。当这种飞机制造出来后被涂成深蓝色,在天空中根本看不出其踪影。尽管官方的正式型号称为SR-17,但是最后令它闻名遐迩的名称却是其绰号“黑鸟”。直至今天,这种飞机仍然保持着军用飞机飞行速度的世界纪录。 On July 25, 1964, U.S. President Lyndon Johnson announced the development of a new aircraft that will be used for photo-reconnaissance in-depth enemy territory that will use the most sophisticated electronic equipment and surveillance systems to fly Height and speed will make other aircraft catch up. When the aircraft was manufactured, it was painted dark blue and could not be seen in the sky. Although the official official model is called the SR-17, the ultimate name for it is its nickname “Blackbird.” Until today, this aircraft still maintains the world record of military aircraft flight speed.
