The 9M53F fragmentation and blast projectile has a detachable head part, on which the 9E260-1 safety electron-mechanical remote contact fuse of remote contact type is installed. On the final section of the trajectory the HF meets the ground practically vertically, due to which the circular fly of the striking elements is provided, which increases the area of the continuous defeat. Shots can be fired in single shots and volleys. The duration of the salvo is 30 seconds. Firing is controlled from the cockpit or by remote control.
