North Korean leader Kim Jong-un supervised live-fire tests of upgraded missile launchers, tactical ballistic missiles, and artillery systems on June 25, 2023 [1].

These tests signal Pyongyang's intent to accelerate its military capabilities during a period of heightened regional instability. The drills occurred as the U.S. and South Korea began joint military exercises, which North Korea frequently views as provocative.

The exercises took place at a naval base and an artillery training ground, including the destroyer Choe Hyon [1]. According to reports, the military test-fired strategic cruise missiles and anti-ship missiles [1]. Other reports described the tests as involving hypersonic missiles [2].

Kim Jong-un framed the activity as a component of the country's five-year defence modernization plan [3]. State media said that the leader expressed satisfaction with the results and noted that the tests demonstrated progress under the national plan [2].

The timing of the drills coincided with the 76th anniversary of the Korean War [1]. This anniversary serves as a symbolic backdrop for the display of military force.

"The test was a great success and demonstrated the strong combat power of our armed forces," KCNA said [1].

The North Korean state news agency said that the exercises highlighted the operational readiness of the upgraded systems. The integration of naval assets like the Choe Hyon suggests a focus on expanding maritime strike capabilities, a key pillar of the current defence strategy [1].

"The test was a great success and demonstrated the strong combat power of our armed forces."

The synchronization of these tests with the anniversary of the Korean War and concurrent U.S.-South Korea drills serves as a dual-purpose signal. By demonstrating upgraded cruise and anti-ship capabilities, North Korea is attempting to validate its five-year modernization plan while asserting a deterrent posture against foreign military presence on the peninsula.
