Why North Korea and South Korea Are Testing Missiles

What happened in the latest North Korean missile launch?

South Korea’s military said North Korea launched multiple ballistic missiles from the area around Pyongyang toward the sea on Monday morning. Ballistic missiles travel on a high arc after launch. South Korea reported that one missile flew more than 900 kilometers before falling into the water ¹.

The reports do not give a fully consistent count. South Korea’s account described multiple missiles but did not provide a precise number in the available report. Japan’s Defense Ministry said it detected at least two and assessed that they landed outside Japan’s exclusive economic zone, the waters where a country has specified economic rights ¹².

Why did the launches follow South Korea’s hypersonic test?

South Korea flight-tested its first domestically developed hypersonic weapon on Friday. President Lee Jae Myung described the test as a step toward strengthening the country’s conventional defenses. Hypersonic weapons are designed to travel at least five times the speed of sound; the report says this weapon is intended to make interception harder ².

South Korea’s Joint Chiefs of Staff called North Korea’s Monday launch a show of force in response to the South’s test, and said it also demonstrated missile capabilities ¹. That is the South Korean military’s interpretation. The sources do not provide a direct North Korean explanation for Monday’s launches, so the precise motive remains uncertain.

What do the tests mean for regional security?

The launches show that both Koreas are developing or demonstrating weapons as tensions continue. South Korea presents its hypersonic test as part of conventional defense. North Korea has been testing weapons as it expands an arsenal that includes systems described as capable of carrying nuclear weapons ².

More tests can make it harder for governments in the region to judge one another’s capabilities and intentions. Japan also monitors launches that could affect its security. But these reports do not say that Monday’s missiles struck land, caused damage, or changed the military balance. They describe missiles falling into the sea ¹².

Is this part of a larger pattern of weapons tests?

Yes. DW reported that Monday’s launch was North Korea’s fourth missile launch in October and said the country had carried out tests on more than ten occasions that year ¹. CBS also described a recent streak of weapons demonstrations during a prolonged freeze in diplomacy between the Koreas ².

The activity is not limited to the Monday launch. CBS reported that North Korea tested what it described as a hypersonic intermediate-range missile on October 3, and had also held other missile tests and live-fire drills ². North Korea’s description of a weapon is not, by itself, independent confirmation of its performance.

What is still unknown about Monday’s missiles?

The reports leave several details unsettled, including the exact number and type of missiles and their full flight paths. South Korea and Japan reported detections, but the available accounts do not include a detailed technical assessment of each weapon ¹².

The sources also do not confirm North Korea’s reason for launching the missiles or say whether the launches were planned specifically as a response to South Korea’s test. More information from official military assessments could clarify those points.
