North Korea test-fired a possible Submarine-Launched Ballistic Missile (SLBM) on Oct. 2, South Korea’s Joint Chiefs of Staff (JCS) said in a statement.
The launch came just hours after Pyongyang said it would resume nuclear talks with the United States.
The missile was launched from near the port of Wonsan and flew about 450km (280 miles) and reached an altitude of 910km, before landing in the Sea of Japan, according to South Korean officials.
The missile is “believed to be one of the Pukkuksong models”, added the JCS statement, referring to a line of SLBMs under development by the North. The North carried out a successful test of the Pukkuksong-1, also known as KN-11, in August 2016 which flew around 500 kilometres.
In July this year, North Korean state media has released images of its leader Kim Jong Un inspecting a new submarine under construction. According to reports, the submarine appeared to be a modified version of the Chinese Type 033 Romeo-class submarine capable of carrying SLBMs.
