The oxidizer and fuel tanks were placed fence devices that track the position of the fuel components at high alternating transverse accelerations. oxidizer supply pipeline runs under the cover of the box on the right side rocket, and a box for the wiring board cable network was placed on the opposite side of the body. Onboard power supply 5I43 provided electricity generation in flight (AC and DC), as well as the creation of high-pressure hydraulic system for steering gears. Rockets starting engines equipped with one of two modifications - 5S25 and 5S28. The nozzles of each accelerator inclined relative to the longitudinal axis of the housing so that the thrust vector passing in the vicinity of the center of mass of the missile and arranged diametrically raznotyagovost accelerators reaches 8% to 14% 5S25 and 5S28 to not create unacceptably high disturbing moments in pitch and yaw. In each of the okolosoplovoy accelerator supports two console fastened to the seventh compartment sustainer stage - the cast ring discharged after separation accelerator. In front of the accelerator two similar towers in touch with the power of the frames in the case of a rocket intertank compartment area. Mounts to the seventh compartment provided cranking and subsequent separation of the accelerator after the rupture of relations with the opposite of the front unit. On each of the accelerators was placed on the stabilizer, while on the lower accelerator regulator was formed in the direction of the left side of the rocket and the working position only after the descent of the rocket with PU.
