On Saturday, state TV showed images of the Pukkuksong-2 SLBMs and several KN-08 and KN-14 missiles on trucks along with tanks and other heavy military hardware being paraded on Kim Il Sung Square in the capital, Pyongyang.
Leader Kim Jong-un oversaw the parade which was celebrating the 105th birthday of state founder Kim Il Sung, his grandfather. He also addressed thousands of soldiers and people taking part in the celebrations.
The event also paraded what appeared to be a new intercontinental ballistic missile (ICBM).
It is the first time North Korea publicly displays the ballistic missiles, which have a range of over 1,000 km (600 miles), at a military parade.
The parade comes as tensions have been simmering between North Korea and the US in recent weeks, raising fears of a potential military confrontation between the two sides.
Washington has voiced concerns over Pyongyang’s nuclear tests, but the North says such launches are an act as deterrence against a potential invasion by the US or South Korea.
Prior to the parade, Kim’s close aide Choe Ryong-hae also addressed the participants, voicing the country’s readiness to respond in kind to any attack by enemies.
“We’re prepared to respond to an all-out war with an all-out war and we are ready to hit back with nuclear attacks of our own style against any nuclear attacks,” Choe said.
Choe, who is believed to be the second-most powerful official in North Korea, further stated that the new US government under Donald Trump was “creating a war situation” on the Korean Peninsula by dispatching strategic military assets to the region.
