North Korea said Friday it successfully tested a super-large multiple rocket launcher's successive firing system under leader Kim Jong-un's guidance in the launch of two projectiles the previous day.

On Thursday, South Korea's military said the North fired two projectiles from what is presumed to be a super-large multiple rocket launcher from Yeonpo in the country's eastern South Hamgyong Province toward the East Sea.

The North's official Korean Central News Agency said the Academy of Defence Science conducted the drill to "finally examine the combat applicability" of the launcher. Kim expressed "great satisfaction" over the test results.

The test-fire "proved the military and technical superiority of the weapon system and its firm reliability," the report said.

The commanders of the North's military expressed gratitude to the leader "who saw to it that lots of arms and equipment of powerful performance were developed and perfected this year for the military and technical strengthening of the Korean People's Army," it said.
