North Korea's official news agency said Friday that the country successfully tested a super-large multiple rocket launcher the previous day, adding that it verified the "perfection" of the weapons system.

On Thursday, South Korea's military said that the North fired two short-range projectiles from its western region toward the East Sea, saying both flew about 370 kilometers.

"The Academy of Defense Science of the Democratic People's Republic of Korea succeeded in another test-fire of super-large multiple rocket launchers on Thursday afternoon," the Korean Central News Agency said.

"The perfection of the continuous fire system was verified through the test-fire to totally destroy with super-power the group target of the enemy and designated target area by surprise strike of the weapon system of super-large multiple rocket launchers," the KCNA added.

North Korean leader Kim Jong-un expressed "satisfaction" over the test-firing and sent congratulations to the national defense scientists developing the "self-defensive military muscle of the country," it said.
