so what the advantages of each designed in term of accuracy ,penetration , ability to hit moving target ? ( i mean does the aerodynamic different offer the different capability as well )
P/S : in another forum there was a guy saying that due to aerodynamic JDAM design often get problem with vertical development and Paveway series get problem with stalling but i dont really understand there terms can anyone explain it more clear
The kits have no effect on the penetration capability and are often standard equipment because the smaller bursting charge in penetrating warheads requires greater accuracy to be effective.
In terms of accuracy, GPS guidance is an all weather capability but is limited to stationary targets. Laser guidance is more accurate and can hit moving targets, but requires that the target be illuminated by a coded laser beam, so it is a clear weather only system, and generally requires the aircraft to overfly the target. The latest version of both JDAM and Paveway gives them both capabilities.
Not sure what is meant by
vertical development, but if he meant the ability to strike vertically downward, there is no problem. Within the limits of the available kinetic energy and control surface the trajectory of a JDAM is programmable. Also, because the JDAM is largely unaffected by the accuracy of the launch trajectory, it is common to use ‘toss bombing’ techniques where it is launch it upward on a ballistic trajectory toward the target and come down on it. This also allows the aircraft to avoid overflying the target and leave as fast as possible.
