North Korean leader Kim Jong Un has unveiled a new naval destroyer, claiming it as a significant advancement towards his goal of expanding the operational range and preemptive strike capabilities of his nuclear-armed military.

Reuters reported that North Korea's new class of warship was able to accommodate dozens of vertical launch cells to carry missiles its military has already developed.

Kim Jong-un and his daughter have launched a new warship armed with “the most powerful weapons”, North Korean state media said on Saturday.
