The Jerusalem Post reports: “North Korean leader Kim Jong Un observed construction of a submarine with his daughter, a potential heir, and oversaw the test-firing of long-range surface-to-air missiles, state media reported on Thursday.

Wednesday’s missile test near the east coast, aimed at assessing the nuclear-armed country’s strategic technology for developing a new type of high-altitude missile, destroyed targets in the air from 200 km (120 miles) away, KCNA said.

South Korea’s Joint Chiefs of Staff confirmed the missile test occurred at 5 pm, Yonhap News Agency reported. The South Korean military had been aware of launch preparations and was ready for it, Yonhap said, citing a Joint Chiefs official.

Kim observed construction at another site on an 8,700-ton nuclear-powered submarine capable of launching surface-to-air missiles, KCNA said. It did not identify the location or date of his visit.

The submarine project is part of the ruling party’s effort to modernize North Korea’s navy, one of five key policies the party is pushing to develop the nation’s military capabilities, KCNA said…”
