North Korea has displayed the new Pukguksong-1 submarine-launched ballistic missiles for the first time on Saturday ahead of a massive military parade in the capital, Pyongyang.

The country’s hereditary leader Kim Jong-un, wearing a black suit and white shirt and a tie, welcomed his country’s bravest as he addressed thousands of soldiers who took part in the parade honoring his grandfather.

The military parade displayed submarine-launched ballistic missiles for the first time and what appeared to be a new intercontinental ballistic missile, in addition to others that have already been publicly unveiled, South Korea’s Yonhap News reported. In 2012, North Korea unveiled long-range missiles that some arms analysts dismissed as fake.

South Korean military officials said they regard it as a new type of ICBM.

“It’s presumed to be a new ICBM. It seems longer than the existing KN-08 or KN-14 ICBMs, an official said.

The North also showed off various other ballistic missiles including what it claims to be a submarine-launched ballistic missile (SLBM).
