Abstract: Aerial bombardment is one of the usual missions of the Air Force and is very effective and vital in supporting the troops in the battlefields as well as in humanitarian aid. Air bombardment and unguided bombing operations are very similar in terms of operation. The bombing operation (which was initially carried out by balloons) has a history of more than a century and a half in the world, and in world wars, especially World War II, it was especially valued and advanced techniques for Precise and targeted bombings were invented. Today, in modern airplanes, these targets are carried out by automatic systems installed on the airplane, and all the necessary calculations for accurate bombing are done automatically. But the targeting systems on older planes still need to be upgraded. In this article, while briefly reviewing the history of bombardment and bombing in the world, the results of our own calculations and simulations in the field of accurate bombardment are presented. Various parameters, including the effect of air resistance and wind speed, have been considered in the calculations, and the results have been discussed. The purpose of this research was to simulate and produce a software package in order to equip UAVs with a precise loading system, which has been achieved.
