The I-122-F round with a full charge is fitted with an I-122 illuminating grenade.
The I-122 grenade represents a body containing an illuminating body and a parachute system, which during flight are ejected in the direction opposite to the flight direction. Once the parachute system has deployed, it begins to descend at a uniform rate to the earth surface.
The system illuminates suddenly the terrain, featuring the following advantages over the other means of illumination: located within a short distance from the illuminated object; illuminates a wide area; low vulnerability of the source of light during its operation.
