SEOUL – North Korea will equip its military with a new 240-millimeter multiple rocket launcher starting this year, state media said on Saturday, adding that a "significant change" for the army's artillery combat capabilities was underway.

Leader Kim Jong Un on Friday oversaw a live-fire test of the "technically updated" rocket system, Pyongyang's official Korean Central News Agency (KCNA) said.

The announcement comes as analysts say the nuclear-armed North could be testing and ramping up production of artillery and cruise missiles before sending them to Russia for use in Ukraine.

Pyongyang said in February it had developed a new control system for its 240-mm multiple rocket launcher that would lead to a "qualitative change" in its defense capabilities, and last month executed a test-firing of new shells.

The updated rocket launcher will be "deployed to units of the Korean People's Army as replacement equipment from 2024 to 2026," KCNA said.

South Korea's Defense Ministry told Agence France-Presse (AFP) it could not confirm the Friday test launches.

But Pyongyang said eight shells had a "hit point target to intensively prove the advantage and destructive power of the updated 240mm multiple rocket launcher system."

Images released by state media showed Kim conversing with military officials during an inspection of the launcher, as well as what appeared to be the live-fire test of the system.

The tests also proved the power of the "controllable shells for [the] multiple rocket launcher," KCNA said.

The largely isolated country has recently bolstered military ties with Russia, and Pyongyang thanked Moscow last month for using its United Nations Security Council veto to block the renewal of a panel of UN experts that monitored international weapons sanctions on Kim's regime.

South Korea and the United States have accused North Korea of supplying weapons to Russia, despite UN sanctions banning such a move.

KCNA said on Saturday that Kim discussed ways to raise production of the new rocket launcher system and shells to "the highest level."

It also said a "significant change will be soon made in increasing the artillery combat ability of our army," without providing details.

Inter-Korean relations are at one of their lowest points in years, with Pyongyang declaring Seoul as its "principal enemy." It has jettisoned agencies dedicated to reunification and threatened war over "even 0.001 mm" of territorial infringement.

While escalating its military threats toward South Korea, the North is "also signaling its intentions to participate in weapons exports and other defense-related economic activities via ongoing technical advancements," said Yang Moo-jin, president of the University of North Korean Studies in the South's capital Seoul.

In the context of the ongoing conflict in Ukraine, Pyongyang has "indirectly verified the performance of its existing weapons" by supplying them to Russia, he told AFP.
