Description: The actuality of substantiation of rational approaches to planning combat actions with the use of unmanned combat air ve-hicles (UCAVs) specifies the necessity of development of such actions assessment. This research has great application relevance. The article presents the approach to simulation assessment model of UCAVs’ actions development. The scope of research covers the UCAVs’ operation. The aim of research is to substantiate the development approaches of UCAVs’ actions assessment means based on simulation model. The number of iterations depends on accuracy demand. The UCAVs’ operation is displayed in space and time. The model time is changed discretely with preset augment. The targeting situation is formed before the beginning of simulation model activation. Objects that will be attacked by UCAVs are discovered with reconnaissance means with preset in-tensity. It is assumed that random time of target acquisition has exponential distribution. The time of target acquisition is ran-domly set for each iteration. The number of targets and time of their acquisition will differ in each iteration. Each detected tar-gets randomly gets coordinates in X and Y axes within the controlled area with preset dimensions. The coordinates of UCAV are also set randomly. The approaching time is calculated based on preset UCAV’s speed and distance to the target. The observation time of detected target is random by its nature. The maximal observation time of detected target is set as initial condition. The observation time of detected target for each case is get by multiplying of this time by the random number in the bracket between zero and figure one obtained due to uniform density rule. If the target is observed during approach, it is put on attack. The target engagement is determined on single toss approach. During operating of simulation model, the number of detected targets and the number of engaged targets are calculated. Obtained statistic data are processed after the set number of realizations is finished. Estimations of expectation of detected and engaged targets’ numbers are obtained based on corresponding calculators’ data. The proximity of target engagement by the given number of UCAVs and preset patrolling time in the control area is assessed. The operation research methods were used in the realization of the model. Presented model combines such parameters as dimen-sions of patrolling area, target acquisition intensity, number of UCAVs, their armament and speed. Required dependences be-tween these parameters can be discovered by changing them. This can be the background of finding rational ways of UCAVs’ operation within set conditions.
