The Pukguksong-1 (Korean: 북극성-1; lit. Polaris 1), also known as KN-11 in intelligence communities outside North Korea, is a North Korean two-stage solid-fueled submarine-launched ballistic missile (SLBM) that had a complete, successful test on 24 August 2016.
North Korea has never announced the actual operational range and payload, as this technical information is probably considered classified.
