North Korea appears to have resumed construction of a long-delayed naval base on its east coast, as Pyongyang accelerates efforts to modernize its fleet with new destroyers and a nuclear-powered submarine. NK News said the activity could indicate that North Korea is seeking to expand the size and functions of the facility beyond its original plans. North Korea built more than 10 piers and docking facilities capable of accommodating large warships and submarines between 2015 and 2017. The renewed construction comes as North Korea rapidly expands its naval capabilities. Kim has also called for the Navy to develop into a force capable of regularly operating beyond North Korea’s territorial waters.
