North Korea expands weapons plant that makes missiles used by Russia, researchers say

CNN —

North Korea is expanding a weapons plant that manufactures missiles used by Russia against Ukraine, according to new research from a US-based think tank.

The facility produces both KN-23 missiles (Hwasong-11A) and KN-24 missiles (Hwasong-11B), according to researchers at the James Martin Center for Nonproliferation Studies at the Middlebury Institute of International Studies.

Located in the country’s second-largest city, Hamhung, the factory has been visited several times by North Korean leader Kim Jong Un, with North Korean state media previously touting its mass-production of tactical missiles.

Ukraine has been hit by a recent surge in Russian ballistic missile attacks, about a third of which used North Korean weapons, according to Ukrainian military officials.

Moscow and Pyongyang have also deepened their military ties to a level unseen since the Cold War, including agreeing to a mutual defense pact earlier this year and sending North Korean troops to help fight against Ukraine according to Western and South Korean officials.

Now, new satellite images indicate North Korea is expanding the Hamhung facility and building what appears to be a second building for the final assembly of missiles, as well as additional housing for workers.

“It seems like this is an attempt to increase the throughput on that production line that they’ve established,” Sam Lair, a research associate at the Center for Nonproliferation Studies, told CNN.

Lair said researchers have seen a lot of expansion at the facility, which is called the ‘February 11 plant’ by North Korean authorities, in the last few years alone. The size of the plant started to increase in 2020, and it has since undergone routine improvements like repairing old
