Every few weeks, the same headline appears: North Korea has fired missiles into the sea. Neighbours protest. Emergency meetings are held. Then, after a few days, life returns to normal, until the next launch. Readers often ask the same question: why does North Korea keep doing it? The answer is not one reason. It is several reasons at once, and they have stayed largely the same for years.
This post sets out the main explanations offered by analysts, in plain words. It does not claim to know what is in any leader’s mind. It reports what experts say, and what the pattern of launches shows.
The Short Answer First
North Korea tests missiles to build better weapons, to show that its weapons work, to deter its enemies, to answer military exercises by its rivals, and to send messages at home and abroad. A single launch can do several of these jobs at the same time. That is why launches keep happening even when they bring condemnation, sanctions and angry neighbours. For Pyongyang, the benefits of testing appear to outweigh the costs.
Analysts quoted by Astro Awani put it simply: North Korea tests and demonstrates its weapons for technical progress, propaganda value, exercising crew readiness and capability, and demonstrating that deterrence goes both ways. Each of those reasons deserves a closer look.
Building And Proving New Weapons
The most practical reason is technical. A missile that has never been flown is only a promise. Engineers need to test whether it launches correctly, flies the planned distance, and lands where expected. Each test gives data that cannot be gained any other way. If something fails, it can be fixed. If it works, confidence grows.
North Korea has tested many kinds of missiles over the years, from short-range weapons to long-range ones. In October 2026, for example, it fired several ballistic missiles of different types from near Pyongyang toward the East Sea, with some flying more than 900 kilometres, according to South Korea’s Joint Chiefs of Staff. Testing different types in one launch event lets engineers check more than one system at once, and lets commanders practise handling several launches together.
Deterrence Means Making Threats Believable
The second reason is deterrence. Deterrence means convincing a possible enemy that attacking would be too costly to try. A country that only talks about weapons is less convincing than one that shows them working. Regular tests are a way of saying: our weapons exist, they fly, and we can use them.
Professor Takashi Kawakami of Takushoku University in Tokyo told Astro Awani that North Korea is aiming to increase its deterrence capabilities. Professor Mason Richey of Hankuk University of Foreign Studies in Seoul made a related point: North Korea tests to demonstrate that deterrence goes both ways. In other words, Pyongyang wants its rivals to feel the same caution it feels when they stage large exercises near its borders.
Answering Allied Military Exercises
A third reason is reaction. North Korea strongly dislikes large combined military exercises by South Korea and the United States, especially when they involve stealth aircraft. In 2022, analysts linked a record week of missile tests to the Vigilant Storm drills, which involved around 240 South Korean and American warplanes flying missions around the clock.
Richey explained that North Korea really does not like these large combined air exercises, especially since they employ F-35 jets that can be used for strikes against the regime and are very difficult for North Korean air defences to pick up. Hours before launching 23 missiles of various types into the sea on one Wednesday, the most in a single day at that time, North Korea issued another condemnation of the drills.
The pattern is familiar. The allies say exercises are defensive and meant to deter war. North Korea says they are rehearsals for attack. Each side’s show of strength prompts the other’s, and missile tests are Pyongyang’s loudest answer.
Sending Messages To Washington And Seoul
Missile tests are also a form of communication. They carry no speech and no letter, but they are read carefully in Seoul, Tokyo and Washington. A launch says: pay attention to us, take our demands seriously, and do not ignore us. Analysts say North Korea uses tests to press the United States, in particular, to change policies it calls hostile.
Professor Yang Moo-jin of the University of North Korean Studies in Seoul told Astro Awani that Kim Jong Un’s focus was on pressing the United States ahead of its midterm elections, by emphasising to voters that American policy toward North Korea had failed. Tests timed around elections, summits or policy debates are often read as attempts to shape the political calendar of other countries, not only as weapons trials.
Messages For Audiences At Home
There is also a domestic audience. North Korea’s economy has faced great hardship, and its people live under tight control. Missile launches are shown at home as proof of strength, progress and leadership. They tell a story in which a small, isolated country stands up to much larger powers and is not afraid.
Yang also said Kim wants to bolster internal support for his government during economic hardship at home, and to demonstrate that when it comes to Korean peninsula issues, he is in the driver’s seat. A successful launch is a useful symbol for that story. It needs no translation, and it can be repeated on television again and again.
Practising Crews And Readiness
Missile tests are not only about machines. They are also about people. Crews must practise fuelling, aiming, launching and moving equipment under pressure. A test is a rehearsal for the day a weapon might really be used. Richey included exercising crew readiness and capability among the reasons for testing, and it is easy to see why: an untested crew is as risky as an untested missile.
Large salvoes, in which many missiles are fired at once, practise something more. Adam Mount of the Federation of American Scientists said that simultaneous launches of short- and long-range missiles suggest North Korea is practising plans to attack distant targets during a conflict on the peninsula. The point is not only that each missile works, but that many can be fired together, in a coordinated way.
Propaganda Value And Bargaining Power
Every test also creates bargaining power. A country that is visibly improving its weapons is harder to ignore in talks. Analysts note that North Korea has sometimes raised tensions before negotiations, in the hope of winning concessions or attention. Mount said the 2022 launches were calibrated to escalate tensions, and warned that Pyongyang might be setting the stage for something bigger, such as a nuclear test.
Professor Park Won-gon of Ewha Womans University in Seoul added a longer-term aim: Kim would likely be seeking tacit recognition as a nuclear weapons state, and to negotiate nuclear disarmament with the United States by making denuclearisation an unrealistic goal. Whether or not that aim succeeds, tests keep the issue at the top of the agenda. Silence, by contrast, would let the world look away.
What Missile Tests Do Not Prove
It is important to be careful about what tests do and do not show. A successful test shows that a missile flew. It does not prove that North Korea would use it, or that it could win a war. It does not prove that sanctions have failed or succeeded. And it does not tell us what Pyongyang will do next.
Tests also do not happen in a vacuum. Each launch is followed by protests, meetings and statements, and each response shapes the next round. The cycle of test and response has continued for years, through sanctions imposed since 2006 over North Korea’s nuclear and missile programmes. Understanding the cycle is more useful than reacting to any single launch as if it were the whole story.
Why The Launches Continue
Put the reasons together and the pattern becomes clear. Tests improve weapons, practise crews, deter enemies, answer exercises, press rivals, reassure audiences at home, and keep North Korea at the centre of regional diplomacy. No single reason explains every launch. Different launches may stress different reasons. But the combination explains why condemnation alone has not stopped them.
For ordinary readers in Japan and South Korea, the launches are not abstract. Missiles fly over nearby seas in minutes. Emergency alerts, protests and meetings follow. Yet daily life usually goes on, because most tests end in the sea and harm no one directly. The fear is about what the pattern means, not only about what one missile did.

Frequently Asked Questions
Why does North Korea test missiles so often?
North Korea tests missiles for several reasons at once: technical progress, propaganda value, exercising crew readiness and capability, and demonstrating that deterrence goes both ways, according to analysts quoted by Astro Awani. Tests let engineers check new weapons, let crews practise launches, and show rivals that the weapons work. A single launch can also send political messages abroad and at home, which is why launches keep happening even though they bring condemnation and sanctions.
Is North Korea testing missiles because of US and South Korean military drills?
Military drills are one important trigger, analysts say. North Korea strongly dislikes large combined air exercises by South Korea and the United States, especially when they involve F-35 stealth jets that are hard for its air defences to detect. In 2022, a record week of tests followed the Vigilant Storm drills involving around 240 warplanes, and North Korea condemned the drills hours before firing 23 missiles in a single day. The allies describe the exercises as defensive, while Pyongyang treats them as rehearsals for attack, so each side’s show of strength tends to prompt the other’s.
What does deterrence mean in the North Korea missile tests?
Deterrence means convincing a possible enemy that attacking would be too costly to attempt. North Korea tests missiles to make its threats believable: a weapon that has been seen flying is more convincing than one that only exists on paper. Professor Takashi Kawakami said North Korea is aiming to increase its deterrence capabilities, and Professor Mason Richey said the tests demonstrate that deterrence goes both ways, so that rivals feel the same caution Pyongyang feels during their exercises.
Do missile tests help North Korea at home?
Yes, analysts say tests also serve a domestic purpose. Professor Yang Moo-jin said Kim Jong Un wants to bolster internal support for his government during economic hardship at home and to show that he is in the driver’s seat on Korean peninsula issues. A successful launch is shown at home as proof of strength and progress by a small country standing up to much larger powers, and it needs no translation to make that point.
What do North Korea missile tests not prove?
A successful test proves that a missile flew, but it does not prove that North Korea would use it, that it could win a war, or what Pyongyang will do next. It also does not by itself prove that sanctions have failed or succeeded. Each launch is part of a longer cycle of test and response that has continued since UN sanctions began in 2006, and understanding that cycle matters more than treating any single launch as the whole story.
