one Syrian. Operation An unguided bomb fitted with a Spice kit can contain up to 100 images of its potential targets. The bomb is then loaded on a strike aircraft. In the pylon to which the bomb is attached, there is a data link between the aircraft's cockpit and the bomb. As the aircraft flies in the air and approaches a target, either the weapon systems officer (WSO – the back seater in such aircraft as the F-15E Strike Eagle or F-16I Sufa) or pilot (in single-seat aircraft) can use the TV/IIR display in the cockpit to see the image the bomb sends to them. Once they have selected one of the preprogrammed targets or manually fed the bomb with a target (by feeding it with either an image or geographical coordinates to home on), the bomb is ready for release into a guided trajectory. Once the bomb is released, it begins searching for its target to acquire it and home in on it. This can be done in several ways: First, there is pure CCD or IIR (for low lighting conditions) image matching, when the guidance section uses algorithms to match the target image in its memory with the image provided by the seeker and align the center of the seeker's FOV with the desired image (a guidance method known as DSMAC). Second, if the CCD\IIR seeker cannot acquire its target for any reason (such as visual obstructions), the bomb can automatically switch to GPS\INS guidance. This means that the bomb aspires to bring itself to the target's altitude at a known geographical location. The bomb receives data on its current location from GPS satellites, or from an inertial navigation system in the bomb itself, that has been fed, through the pylon datalink, with the dropping aircraft's coordinates a fraction of a second before the drop and can therefore calculate its coordinates from the dropping time and on. Third, there is a manual "man-in-the-loop" guidance option, in which the WSO looks at a backseat TV display to see the seeker's view (sent to them through a RF command guidance datalink) and uses the backseat stick to control the bomb to the target. With a skilled WSO that has a "sensitive hand", this guidance method is potentially the most accurate one employed today for air-dropped munitions and has no measurable miss distance. Its main drawback is that it allows for
