Pyongyang: North Korea has successfully test-fired an upgraded large-caliber multiple rocket launcher system (MRLS), with leader Kim Jong-un overseeing the operation, as reported by state media on Wednesday.

According to Yonhap News Agency, the test conducted on Tuesday involved the launch of four MRLS rockets employing new technology, which successfully hit a target located 358.5 kilometers away. This test follows an announcement from South Korea's military, which had detected multiple short-range ballistic missiles launched from north of Pyongyang toward the East Sea. The test coincides with expectations that North Korea will soon convene its first ruling party congress in five years.

Kim Jong-un emphasized the significance of the test, stating that it plays a crucial role in improving North Korea's strategic deterrence capabilities. He highlighted enhancements made to maximize the launcher system's strike capabilities, including its mobility, intelligence, and accuracy. Kim also pointed out the weapon's advanced "self-steered precisely guided flight system" as a key feature, underscoring ongoing advancements in the country's defense technology.

The North Korean leader reiterated that these activities aim to elevate the country's deterrence level against a nuclear war. He emphasized that building a reliable offensive capability and enforcing a deterrence strategy is a core component of the national defense policy.

Photos released from the test event show Kim's daughter, Ju-ae, accompanying him, along with Kim Jong-sik, the first vice department director of the party's Central Committee, and Jang Chang-ha, chief of the Missile Administration. This missile launch appears to assert North Korea's growing military capabilities as it prepares to unveil new five-year development plans at the upcoming party congress.

Additionally, the test coincided with the visit of U.S. Under Secretary of Defense for Policy Elbridge Colby to South Korea, where he discussed security issues, including Seoul's ambitions to develop nuclear-powered submarines. Colby concluded his three-day trip to Seoul and departed for Japan the day before the test.
