North Korean state media have been quick to release images of the country’s missile tests, the latest of which occurred today

North Korea test-fired what appeared to be cruise missiles yesterday morning, fuelling concerns that it is developing “carrier killer” weapons that could menace the navies of South Korea and the United States.

The fifth missile launch so far this year came on the eve of the birthday of the country’s founder, the late Kim Il-sung, often the occasion for displays of military strength.

Known in North Korea as the Kumsong-3 and to foreign analysts as the KN-19, the missile was last seen in June 2017 when Kim Jong-un witnessed its first test-firing. It
