North Korea says it has successfully tested a “new type” of submarine-launched ballistic missile, as the nuclear-armed country pursues ever more improved weapons.

The device had “lots of advanced control guidance technologies”, the official Korean Central News Agency said on Wednesday, adding that it was launched from the same vessel that the North used in its first submarine-launched ballistic missile (SLBM) tests five years ago. The latter point casts doubt on claims by Pyongyang in 2015 that it had launched a submarine-based missile.

Wednesday’s report did not mention leader Kim Jong-un, indicating he was not present for the event.

Pictures in the Rodong Sinmun newspaper showed the black-and-white missile emerging from the waters trailing a column of fire and smoke, and a surfacing submarine.

In a reflection of international concern, diplomats said that the UN security council would hold an emergency closed-door meeting on Wednesday on North Korea.

Analysts said the images appeared to be one of the missiles Pyongyang put on show at a defence exhibitionlast week.

It was “a bit of flex to launch a new, previously untested missile from a submarine for the first test”, said Ankit Panda of the Carnegie Endowment.

A proven submarine-based missile capability would take the North’s arsenal to a new level, allowing deployment far beyond the Korean peninsula and a second-strike capability in the event of an attack on its military bases.
