North Korea has fired another suspected ballistic missile into waters off its eastern coast while warning that it must strengthen its ability to respond to hostile military action with attacks capable of preventing an adversary from recovering.
The launch came as Pyongyang sharply criticised plans by South Korea to develop nuclear-powered submarines, describing the programme as a development that could increase military tensions on the Korean Peninsula and across the wider region.
The latest missile activity adds another layer of tension ahead of major military exercises involving South Korea and the United States, which North Korea has repeatedly condemned as preparations for an attack.
According to South Korea’s Joint Chiefs of Staff, the missile was launched from the Wonsan area at around 6am local time on Wednesday. Japanese and South Korean authorities said it travelled approximately 700 kilometres before landing in waters off the Korean Peninsula’s eastern coast.
The launch was the second reported missile firing from the Wonsan area in less than a week.
South Korean authorities said the projectile was launched only six days after another ballistic missile was fired from the same general location.
Pyongyang issues stark warning
The missile launch was accompanied by a strongly worded statement from North Korea’s Foreign Ministry, carried by the country’s state-run Korean Central News Agency.
Pyongyang argued that developments in the military capabilities of South Korea and other regional powers required North Korea to maintain an ability to respond to potential attacks.
The ministry said North Korea should be capable of responding to hostile military moves with retaliatory action designed to make an opponent’s “survival and recovery impossible.”
The warning came specifically in response to South Korean plans involving nuclear-powered submarines.
North Korea portrayed the submarine programme as a destabilising development, arguing that the expansion of nuclear-related military capabilities in the region could worsen the already tense security environment.
The statement also reflects Pyongyang’s longstanding argument that its nuclear weapons and missile programmes are necessary to deter the United States and its allies.
Seoul and Washington, however, maintain that their military cooperation is defensive and intended to deter North Korean aggression.
Missile launched before US-South Korea exercises
The latest test occurred days before the beginning of the annual Ulchi Freedom Shield exercises involving South Korean and US forces.
The drills are scheduled to take place from August 17 to August 27 and are designed to strengthen the allies’ ability to respond to a range of security scenarios, including North Korea’s increasingly sophisticated missile and nuclear capabilities.
Pyongyang has consistently opposed the exercises, describing large-scale US-South Korean military activities as evidence of hostile intentions.
The timing of Wednesday’s missile launch therefore attracted particular attention.
Hong Min, a senior researcher at the Korea Institute for National Unification in Seoul, said the test could be connected to North Korea’s established weapons-development programme. However, he noted that the decision over when to conduct a weapons test is itself political.
That means the launch may have served two purposes: advancing technical development while simultaneously delivering a warning before the military exercises begin.
Possible advanced missile technology
South Korean and Japanese authorities have not publicly established the precise type of missile involved.
The reported range of roughly 700 kilometres, together with the trajectory and launch location, has prompted speculation that North Korea may have tested a hypersonic weapon or another advanced short-to-medium-range missile.
Hong also raised the possibility of a submarine-launched weapon.
Determining the missile’s exact characteristics could take additional analysis by South Korean, Japanese and US intelligence agencies.
North Korea has spent years developing a diverse missile arsenal, including short-range systems intended to threaten targets in South Korea and longer-range weapons designed to extend its potential reach.
Its weapons tests this year have included suspected ballistic missiles, artillery rockets and other tactical systems.
South Korean assessments indicate that Wednesday’s launch represents the country’s 11th suspected ballistic missile test of 2026.
The continuing tests demonstrate that Pyongyang’s weapons programme remains active despite international sanctions and repeated calls for restraint.
Seoul and Tokyo condemn launch
South Korea responded by convening an emergency meeting of its national security officials.
The government expressed concern over what it described as North Korea’s continued ballistic-missile activity, particularly following another launch on August 6.
Seoul called on Pyongyang to stop actions that violate United Nations Security Council resolutions restricting North Korea’s ballistic-missile activities.
South Korea’s military also said it was maintaining a strong state of readiness and would respond decisively to any further provocation as part of its combined defence arrangements with the United States.
Japan also condemned the missile launch.
Japanese Defence Minister Shinjiro Koizumi said Tokyo had lodged a strong diplomatic protest through channels involving North Korea’s embassy in Beijing.
The Japanese government has closely monitored North Korea’s missile programme because projectiles launched by Pyongyang can travel over or into waters surrounding Japan, creating a direct security concern for Tokyo.
US says there was no immediate threat
The United States said it was coordinating with South Korea, Japan and other regional partners following the launch.
US Indo-Pacific Command said its initial assessment indicated that the missile did not present an immediate threat to US personnel, American territory or its allies.
The command nevertheless said the incident demonstrated the continuing security challenge posed by North Korea’s weapons programmes.
The United States maintains a substantial military presence in South Korea and regularly conducts exercises with South Korean forces. Washington and Seoul regard the alliance as a central element of their deterrence strategy on the peninsula.
For Pyongyang, however, the continued US military presence and joint exercises remain among the main reasons it gives for expanding its nuclear and missile capabilities.
Rising regional military competition
North Korea’s latest statement about retaliatory capability also comes against a backdrop of increasing military investment by countries across East Asia.
South Korea has been expanding its conventional military capabilities while strengthening security cooperation with the United States and Japan. Japan has similarly increased defence spending and is developing capabilities designed to respond to growing missile threats.
Pyongyang has repeatedly presented those developments as evidence that it faces an increasingly hostile security environment.
The debate over nuclear-powered submarines could further complicate regional tensions.
Such submarines can remain underwater for considerably longer periods than conventionally powered vessels, potentially increasing their endurance and operational flexibility. South Korea’s interest in the technology has therefore attracted close attention from neighbouring states.
North Korea’s criticism indicates that Pyongyang sees the programme not simply as a naval development but as part of a broader shift in regional military capabilities.
Another warning before exercises
There has been no immediate announcement from Pyongyang identifying the exact missile fired from Wonsan.
That leaves analysts waiting for additional information about the weapon’s flight characteristics, purpose and whether the test involved a new system.
Nevertheless, the combination of a missile launch, a warning of devastating retaliation and criticism of South Korea’s submarine ambitions sends a clear signal that North Korea intends to maintain pressure on its neighbours.
The coming Ulchi Freedom Shield exercises could provide another opportunity for Pyongyang to demonstrate its military capabilities.
For Seoul, Washington and Tokyo, the immediate priority will be maintaining readiness while avoiding an escalation that could further destabilise the peninsula.
For North Korea, continued weapons testing appears to serve both military and political purposes: improving its arsenal while reminding its rivals that Pyongyang intends to retain the ability to respond forcefully to any perceived threat.
With the US-South Korean exercises approaching, regional governments are likely to watch closely for further missile launches or statements from North Korea in the days ahead.
