Quick Summary

North Korea recently conducted tests of submarine-launched cruise missiles, according to state media, which stated that the exercises were intended to evaluate their underwater combat systems. The missiles were launched into the East Sea on Wednesday without affecting neighboring countries’ security, as reported by KCNA. Tensions with South Korea have escalated since a landmine blast near the DMZ injured three South Korean soldiers in September, leading both nations to demonstrate advancements in missile technology.

Story summary

On October 14, 2026, North Korea conducted tests of two types of submarine-launched cruise missiles off its eastern coast, according to state media KCNA. The test involved a Pulhwasal-3-31 missile similar to one tested from land the previous week. North Korean officials stated that these exercises aimed to assess the readiness of their underwater combat systems and enhance their strategic military capabilities. No immediate reaction was provided by South Korea's military regarding these tests, which come amid heightened tensions following a September 21 landmine blast in the Demilitarized Zone (DMZ) that wounded three South Korean soldiers. This incident has led to increased missile testing activities on both sides and further deteriorated inter-Korean relations.

Why this leaning score
This article does not take a side on a contested political question, so it has no leaning score. That is an answer rather than a gap: a match report or a rescue can be warmly or critically written without being left or right, and scoring it anyway is how approval of a subject gets recorded as a political position.
