Under the missile system (MS) it is understood that the totality of the functional and technologically interconnected missiles of a particular type, technical means and facilities intended to maintain their readiness for use, launching missiles, controlling their flight, and performing other tasks (for example, protecting a missile from the impact of the attacking factors enemy weapons). The main properties of LWR are survivability, combat readiness, effectiveness of the action on the target, ability to overcome the enemy's resistance, reliability, manageability, reach. The property of the Republic of Kazakhstan as a whole and its constituent parts separately keep in time the ability to perform functions in accordance with the intended use under the specified modes and conditions of operation (at application, maintenance, storage, transportation). The paper considers the concept of reliability of MS, whose increase is considered one of the important tasks. One of the most important indicators of reliability during operation of the LWR is to ensure the mechanical preservation of their component parts. It is understood that the preservation is understood as the ability to preserve the specified mechanical properties, in particular, during and after transportation. In the process of transporting a rocket, its structure is exposed to various external forces that vary in magnitude and time. During operational loads, there is a process of complex interaction of external force factors. Estimated and experimental studies of the effect of actual operational loads on a launcher with a rocket (LWR) present considerable difficulties, especially considering the dynamics of loads. Apart from this, on the PUs there are striking factors, due to the use of weapons by the enemy. These effects can cause damage and failure as separate elements of the LWR and the product as a whole. The use of LWR constantly requires the solution of specific tasks to ensure the mechanical safety of structures, for the solution of which developed new methods. There are differences between the results obtained to ensure the mechanical safety of the components of the MS and the real results obtained on the basis of existing methods. However, the level of development of the means of defeating the enemy, mechanical safety of the components of the LWR, under the influence of vibration and shock loads, is not ensured. In the considered woMS, it is proposed to evaluate the reliability of the launcher with the rocket during the transportation process with a complex indicator - the coefficient of operational readiness of the launcher with the rocket. The given mathematical model of determining the coefficient of operational readiness of the launcher with the rocket during the transport of the rocket.
