2011年5月1日深夜,阿富汗东部的美国空军基地贾拉拉巴德,两架UH-60“黑鹰”直升机悄悄起飞,一共搭载了24名海豹突击队员(每机各搭载12人)。这种“黑鹰”是经过改装的,加大了推力,降低了噪音,还具有一定的隐形能力(防雷达),至今仍属于高度机密。突击队员们都戴着夜视头盔,这种头盔上装有红外线夜视仪,它的成像与人眼构造不同,不依赖于可见光,却能够接收物体散发的热量辐射,在镜片上形成绿色的图像。有了它,即使是在伸手不见五指的黑夜,也能将一草一木看得清清楚楚。
Late on May 1, 2011, two U-60 Black Hawk helicopters took off quietly at the U.S. Air Force base Jalalabad in eastern Afghanistan. They carried a total of 24 SEALs (each carrying 12 people each) . This “Black Hawk ” is modified, increased thrust, reducing noise, but also has some invisible ability (radar), is still a high degree of confidentiality. The commandos all wore night vision helmets equipped with an infrared night vision goggles. Its imaging was different from that of the human eye. Instead of relying on visible light, it was able to receive the heat radiation emitted by the object and form a green image on the lens . With it, even in the dark of the night can not be seen clearly.
