Fighter jets flying in formation during a military parade Thursday evening attended by North Korean leader Kim Jong-un in Pyeongyang's Kim Il-sung Square.
The event was held to mark the end of the eight-day Workers' Party congress.
Going by images released on Friday by the North's state-run Korean Central News Agency, the regime showcased its state-of-the-art weaponry, including a new type of submarine-launched ballistic missile which it presumably labels the Pukguksong-5.
The report called it the "world's most powerful weapon that will overpower the world with our strengthened military technology and underwater strategy."
Other weapons seen rolling through the streets were modified versions of Russia's Iskander-class short-range ballistic missiles one of the North's so-called "strategic weapons" that the regime claims can evade South Korea's missile defense systems.
But unlike the North's last military parade three months ago North Korea did not release images of inter-continental ballistic missiles, which could be aimed at sending Washington a message about its strong military might as denuclearization talks remain in limbo.
South Korea's Joint Chiefs of Staff says it's analyzing the military hardware displayed during the parade.
