Satellite images are currently circulating the media and the net regarding the recent activities of North Korea's nuclear submarine. The pictures show the submarine advancing at North Korea's Sinpo South Shipyard as it prepares to set at sea.

The netting that has been enclosing the barrier was removed and provisions next to the submarine suggests that it could be ready for launch, according to the Daily Mail. The missiles that could be deployed from the vessel are estimated to be larger than the KN-11 ballistic missile which was launched by North Korea on August 24.

North Korean expert Joseph Bermudez the factors point to the submarine's capability to spring into action at any times, according to the Sun. "These two factors suggest that both craft may have recently been at sea or are preparing to go to sea in the near future," he said.

Dictator Kim Jong-un's current nuclear submarine is designed after the Golf-class submarines used by the Soviet Union. The North Korean leader is said to be empowering his military prowess to be ready for any imminent attack to his country.

South Korean Director General of the North's Nuclear Affairs Bureau Lee Sang-haw stated in a presentation regarding North Korea's threat to international nations that the ballistic missiles of the nuclear submarine are a direct danger to the US and stated that "Europe is also within range."

"I am not able to share everything I know because much of the intelligence is classified and I don't want to go into precise details. There are different assessments of North Korea's ballistic missile capabilities, but what is for sure is as they repeat tests, they learn something important," they said in an interview with Daily Star.

In line with the nuclear submarine preparation, Kim Jong-un also strengthens his military manpower by conducting an intense winter training for the soldiers which started on early December and will continue until April next year. The leader ordered the soldiers to train under actual war conditions.

Jong-un is also solidifying his airpower by carrying out fire practice of the Korean People's Army. He expressed satisfaction with the night flight combat drill as the pilots hit designated targets with precision, according to Express. South Korea fears for a possible North Korean invasion as the tyrannical leader continues to fortify his military's defense and offense.
