## Overview North Korea has reportedly used different launch methods to fire two types of cruise missiles from a tactical nuclear-capable submarine, raising questions about the operational readiness of its growing undersea arsenal (SCMP, October 16). ## Key Developments North Korea's official Korean Central News Agency (KCNA) said the country had "test-fired two types of submarine-launched strategic cruise missiles" off its eastern coast (SCMP, October 16). The tests reportedly "contributed to inspecting the regular mobilisation readiness" of its forces, according to KCNA (SCMP, October 16). ## Why It Matters The dual-method launch demonstrates advancing North Korean undersea missile capability, intensifying a regional arms race and raising the stakes for South Korea, Japan, and the US in terms of deterrence planning, especially amid simultaneous strains in the South Korea-US alliance. ## Looking Ahead Further tests and international responses, particularly from Seoul, Tokyo, and Washington, are expected.
