对于绰号为“黑色怪鸟”的美国双座高空高速战略侦察机SR—71,许多航空爱好者是非常熟悉的。然而,它的一种实用的姊妹机,外形与它完全相同的单座型A—12侦察机“牛车”却鲜为人知。这是因为它是专为美国中央情报局研制的,担负有特殊使命的先进侦察机,它不仅对外界保密,而且对美国军界也是高度保密的。1967年前后,这种飞机曾秘密执行了代号为“黑盾”计划的侦察北越等国的任务。在冷战结束后的今天,这段秘史终于会诸于众。
For the US two-seater high-altitude strategic reconnaissance aircraft SR-71, nicknamed “Black Monster,” many aviation enthusiasts are familiar with it. However, a practical sister machine, its single-seat single-seat A-12 reconnaissance aircraft, “Chinatown”, is virtually unknown. This is because it is an advanced reconnaissance plane specially designed for the CIA and undertaking special missions. It is not only confidential to the outside world, but also highly secretive to the U.S. military. Around 1967, this aircraft had secretly executed the task of reconnoiting North Vietnam and other countries codenamed “Black Shield”. Today, after the end of the Cold War, this secret history finally came to light.
