Pyongyang’s state-run Korean Central News Agency (KCNA) reported that the SLBM was successfully launched “in vertical mode” from waters off Wonsan Bay in the East Sea of Korea (Sea of Japan), adding that the test-firing, which “confirmed key tactical and technical indexes”, had “no adverse impact” on the security of neighbouring countries.

The KCNA also stated that the test was of “great significance as it ushered in a new phase in containing the outside forces’ threat to the DPRK [Democratic People’s Republic of Korea] and further bolstering its military muscle for self-defence”.

The media outlet did not provide any more details about the weapon, including whether it was fired from a submarine or a submersible test barge.

That said, the US Deparment of Defense, which described the weapon as a short- to medium-range ballistic missile, said that the SLBM was launched from a sea-based platform.

South Korea’s Joint Chiefs of Staff (JCS) had said the previous day that the missile, which was launched in an easterly direction at 0711 h local time from waters off North Korea’s eastern port city of Wonsan, Kangwon province, flew a distance of about 450 km and reached an altitude of about 910 km before falling into the East Sea (Sea of Japan).
