The AGM-79 Blue Eye was an air-to-ground missile prototype, developed by the United States in the 1960s 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.
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.
Firing trials took place in late 1968, with the prototype missile designated XAGM-79A.
