On Sunday, North Korea said that it has efficiently tested a ballistic missile from a submarine. It also boasted of its emerging ability to eliminate its enemies with a “dagger of destruction.”

However, South Korea was not able to confirm the claim of success immediately. This claim marks Pyongyang’s latest work on expanding its military might while facing pressure from its neighbors and Washington.

The announcement was made by North Korea’s state media on Sunday. The declaration was made after they had fired, what appeared to be, a ballistic missile from a submarine off its eastern coast, says South Korean officials.

Joint Chiefs of Staff of South Korea said that the projectile traveled about 30 kilometers (19 miles) Saturday evening. According to The ABC, the distance is much shorter than the basic distance of a submarine-launched ballistic missile, which can fly at least 300 kilometers (186 miles).

South Korean experts are not convinced that North Korea is currently owning an operational submarine that can fire multiple missiles. However, they agree to the fact that the North is eventually becoming progressive on such technology.

This latest development is quite horrific as successful operational submarine-missiles can be dangerous in the hands of North. If North Korea masters the ability to fire missiles from submerged vessels it would be quite hard for outsiders to detect what North Korea is upto before launching.

Simultaneously, it will also give North the potential to surprise its enemies, says Mashable.

The North’s Korean media said that leader Kim Jong Un had observed the act from the test facility while the ballistic missile was launched from a submarine.

The missile threw out a “massive stream of flames” as it penetrated into the sky and met all technical boundaries.
