North Korea Tests Submarine-Launched Cruise Missiles

North Korea test-fired two types of submarine-launched strategic cruise missiles off its east coast, according to state media KCNA. The Wednesday tests were intended to assess the reliability of the country’s deterrence capabilities and improve the navy’s ability to carry out strategic missions. One of the missiles was a Pulhwasal-3-31, a type North Korea said it had also launched from land the previous week. Senior military officers observed the tests, and KCNA claimed they posed no risk to neighbouring countries. North Korea is not believed to have a modern missile submarine in full operation, although developing one is a key military priority for leader Kim Jong Un. During a visit to a submarine production facility last year, Kim criticised a nuclear submarine deal between the United States and South Korea. State media images from the visit showed an 8,700-tonne nuclear-powered missile submarine under construction; Kim described the US-South Korea deal as a threat to stability on the Korean Peninsula. The tests come amid a recent increase in North Korean missile activity and worsening relations between Pyongyang and Seoul. North Korea has launched multiple ballistic missiles toward the sea and, on October 3, tested a hypersonic intermediate-range missile designed to evade defences in South Korea and Japan. South Korea has also displayed its own hypersonic weapons programme, including a test overseen by President Lee Jae Myung. Tensions have also risen after a landmine blast in the Demilitarized Zone wounded three South Korean soldiers. A joint South Korean-United Nations investigation said North Korean forces planted the mines, prompting Seoul to demand an apology. The article links Pyongyang’s military fortification along the DMZ to Kim’s “hostile-states” policy, which aims to sever ties with South Korea. Diplomatic efforts remain stalled following the collapse of denuclearisation talks between Washington and Pyongyang in 2019. Although Donald Trump has suggested he might meet Kim during his second term, no meeting has taken place.

North Korea said it had test-fired cruise missiles intended for submarine launch, describing the tests as a way to check the readiness of its underwater combat systems and strengthen the Navy. State media said the missiles were tested in waters off the Korean Peninsula’s east coast. It called them “strategic,” a term that suggests they could be intended to carry nuclear warheads, but did not clarify whether the missiles were launched from an operational submarine or an underwater test platform. The test is part of North Korea’s broader development of missile submarines and ballistic and cruise missiles. Pyongyang has conducted a series of weapons tests in recent weeks, presenting them as efforts to strengthen its military deterrence against the United States and South Korea. The article notes that North Korea is not yet believed to have put a modern missile submarine into full operation. The report also describes recent developments in North Korea’s nuclear and diplomatic posture. Two days before the missile test, state media published photos of leader Kim Jong Un visiting a new military museum at an undisclosed location. The museum displayed an intercontinental ballistic missile reportedly capable of reaching the United States. Kim has identified expansion of the country’s nuclear arsenal as a key priority, while denuclearization—the goal pursued by the United States—is described as off the table. Relations between Kim and US President Donald Trump have been quiet since their three meetings during Trump’s first term. Trump recently suggested he might meet Kim during a planned trip to Asia. Meanwhile, North Korea has halted coordination with South Korea and removed references to reunification from its constitution.

North Korea test-fired two types of submarine-launched strategic cruise missiles on Wednesday, October 14, according to state news agency KCNA. The missiles were fired into the East Sea, also known as the Sea of Japan. KCNA said the tests had no adverse effect on neighboring countries and described them as a Navy training exercise intended to assess the readiness of underwater combat systems. The agency said the launches demonstrated the reliability and capability of North Korea’s deterrence forces. The tests took place amid increased tension with South Korea following a September 21 landmine explosion in the Seoul-controlled area of the Demilitarised Zone (DMZ), which injured three South Korean soldiers. Both countries have pursued upgraded missile technologies since the incident. KCNA-released photographs appeared to show missiles launching vertically and at an angle, as well as a missile flying over the sea and a submarine at the surface. Hong Min of the Korea Institute for National Unification told AFP that the two launch angles have different tactical uses: vertical launches may extend a missile’s range, while angled launches can keep it at lower altitude and make it harder for missile defences to detect or intercept. North Korea has conducted submarine missile launches in recent years, but the extent of its sea-based capabilities remains uncertain. Cruise missiles generally fly lower than ballistic missiles, which can make them harder to detect and intercept. A proven submarine-launched ballistic missile capability would represent a more consequential advance, potentially enabling deployment farther from the peninsula and a second-strike capability. The launches come amid multiple missile tests by both Koreas. North Korea conducted several ballistic missile tests in October, while South Korea and North Korea have also tested hypersonic weapons. The article notes that the two countries remain technically at war because the 1953 Korean conflict ended in a truce, not a peace treaty.
