Its one of missiles, called "The AGM-79 Blue Eye" developed by the United States of America. The Blue Eye was a development of the AGM-12 Bullpup, intended to provide a more advanced homing system. The Bullpup was manually steered onto the target, whereas the guidance system in the Blue Eye was an optical area correlation seeker. A TV camera in the missile's nose provided an image to the pilot; he used this to select the target and lock the missile on before firing. Once launched the area correlation system could detect any deviation of the picture compared to the locked image and correct the missile's course accordingly. A radar altimeter was fitted to allow the warhead to explode in an air burst mode.
