The most fearsome nuclear missile launched from a submarine in North Korea is called the Pukguksong-3, and it was successfully tested in 2019.

The Pukguksong-3 is the most dreaded of North Korea’s missiles that are launched from submarines. Pukguksong-3 was initially made public by North Korea in a photograph of its leader, Kim Jong-un, visiting the nation’s missile facility in August 2017. It was successfully test-launched in 2019. According to Pyongyang, the Pukguksong-3 missile’s successful development is crucial for thwarting external threats and enhancing domestic defense capabilities.
North Korea claimed that the successful test contributed to the precise definition of the Pukguksong-3’s tactical and technical indications. North Korea also made sure to underline that the Pukguksong-3 missile’s successful development has no negative effects on the security of its neighbors. The Pukguksong-3 missile, according to analysts, is the most recent model in the Pukguksong family.
Solid fuel is used in the 1,200 km range SLBM Pukguksong-1. The ground-based Pukguksong-2 model, which can strike targets approximately 2,000 kilometers away, also burns solid fuel. Nuclear warheads can be carried by either missile. The Pukguksong-3 missile has a 2,000 km maximum range. The Pukguksong-3 missile’s range will cause the US and South Korea great concern.
North Korea will strengthen its position of power both at the negotiating table and on the battlefield in the event of a confrontation if it continues to possess submarine-launched nuclear ballistic missiles.
