Description: Descriptions of law of errors of aiming of rockets are considered. The mean values of misses of rockets and their среднеквадратические rejections are certain depending on quality of preparation of complex to firing. The values of conditional hit of air unmodel aims probabilities are got. Probabilities of finding of rocket are grounded in the picture plane of firing taking into account the effective surface of dispersion of purpose. It allows to estimate efficiency of firing rockets during conducting of tactical studies.
Keywords: effective surface of dispersion, unmodel purpose, errors of aiming of rockets, conditional hit of purpose probability
