The North Korean single stage Hwasong-12 is a liquid fueled IRBM of estimated 4500 km range.
The Hwasong-2 appears to be related to the Hwasong-13 ("KN-08", "KN-14") IRBM and appears to be single staged.
The missile was first shown in the 2017 military parade and has conducted its maiden flight in May 2017 from a site near Kosong, likely Panghyon Air Base, on a lofted short range trajectory of 787 km range and 2111 km apogee height, which hints to a maximum range of about 4500 km.
