Pyongyang television has aired footage of a reported test of an anti-aircraft defense system, including a rocket launch filmed from several positions, and a view of government officials watching the scene.

The test was followed by an order to start mass production of the system, according to state news agency KCNA.

“This weapon system, whose operation capability has been thoroughly verified, should be mass-produced to deploy all over the country… so as to completely spoil the enemy’s wild dream to command the air, boasting of air supremacy and weapon almighty,” the agency said.

The demonstration was the latest in a series of moves by Pyongyang meant to prove its military prowess. Earlier, it test-launched the intermediate-range Pukguksong-2 ballistic missile.

Rocket tests by Pyongyang unnerve its regional rivals, including South Korea and Japan, which say they need better protection from a possible missile attack by North Korea. Pyongyang insists that it needs a robust arsenal to deter potential aggression by the US and its regional allies.
