The VKS was supposed to take off from standard runways up to 3 kilometers long, fly back to subsonic speed after takeoff to reach the set starting point of acceleration and before landing for approach to a given airfield; carry out flights to change the airfield base, quickly perform acceleration to a given speed and altitude, including access to a circular orbit; perform multiple orbital maneuvers; perform an autonomous orbital flight of up to a day; perform cruising flight in the atmosphere with hypersonic speeds, perform deceleration with deceleration when returning from orbit; in the process of acceleration to orbital parameters and in the process of descending, perform maneuvering for the passage of a given route and exit to a given orbit and a given airfield; change the orbital flight plane.
