The peculiarities of laser radiation delivery to a space vehicle in the concept LOTV which are concerned to the introduction of a lead angle is considered. It is shown that the use of direct phase conjugation of radiation of a laser beacon beam placed on a space vehicle does not provide a required degree compensation of the radiation phase distortions caused by the turbulent atmosphere. Two‐circuit adaptive laser system for high — power radiation delivery is offered in this case. In the system the processes of registration of the information about atmospheric distortions and formation of radiation are functionally partitioned. A key element of the system is a hologram — corrector being phase analogue of distortion occurring in the laser beam path between the system and lead point.
