Although never being officially confirmed, most online analysts believe DF100 is a cruise missile flying in near space driven by a ramjet (not a scramjet), which decelerate the airflow speed to subsonic within the air intake. The missile is supposed to have a cruise speed less than 5 Ma, thus being categorised officially by PLARF as a supersonic cruise missile.Chinese known hypersonics (so far);
