North Korea Cruise Missile Test: 'Nuclear Attack Submarine' Likely Fires First Salvo

North Korea said it tested two types of submarine-launched strategic cruise missiles in the East Sea on October 14, 2026, to assess naval strike capabilities and weapon reliability. State-media imagery suggested the converted missile submarine Hero Kim Kun Ok may have participated, although the launch platform's identity was not conclusively established. The tests represented the first publicly reported underwater cruise-missile launches in nearly three years, following demonstrations of the Pulhwasal-3-31 in January 2024. North Korea's description of the missiles as strategic indicates an intended nuclear role, without independently establishing operational nuclear armament or deployment readiness.
